The Singer 14HD854 combines a heavy-duty metal internal frame, high-output motor, enlarged cutting system, adjustable differential feed and versatile 2, 3 and 4-thread stitching for garments, stretch fabrics, home décor and regular sewing. 2, 3 or 4 thread operation 6 stitch configurations 1,300 SPM maximum sewing speed 60% larger Singer cutting knife View Official Singer Product Page Find the Official Manual A powerful domestic overlocker for high-speed seam construction, professional edge finishing, rolled hems and flatlocking. Professional-looking seams at home The fast way to construct and finish garments The Singer 14HD854 complements your ordinary sewing machine by sewing a seam, trimming the excess seam allowance and enclosing the raw edge with thread in one continuous operation. This creates the neat, flexible and durable finish commonly seen inside professionally manufactured garments. Use it for knitwear, activewear, children’s clothing, woven garments, sweatshirt fabrics, alterations, home décor and decorative edge finishes. Its 2, 3 and 4-thread capability allows the machine to move between secure construction seams, lightweight edge finishing, rolled hems and decorative flatlocking. Singer Heavy Duty performance More cutting capacity and greater sewing stability The 14HD854 is built around a metal internal frame that supports the sewing mechanism and helps keep the machine stable at higher speeds. Singer also equips it with a cutting knife that is 60% larger than the knife used on its standard overlocker models. This provides additional cutting capacity through thicker seam allowances, fleece, sweatshirt fabrics and layered garment intersections. Heavy-duty advantages Metal internal frame High-performance motor Enlarged cutting knife Up to 1,300 stitches per minute Extra-high presser-foot lift Stable high-speed operation Why the Singer 14HD854 stands out Powerful overlocking with practical fabric control 01 60% larger cutting knife Additional cutting capacity helps trim thicker fabrics and layered seam allowances more confidently. 02 2, 3 and 4-thread capability Configure the machine for garment construction, lightweight finishing, rolled hems and flatlocking. 03 Adjustable differential feed Control fabric movement to help prevent stretch seams from waving and fine fabrics from puckering. 04 Built-in rolled hem Move the stitch-finger lever to create narrow rolled edges without changing the stitch plate. 05 Adjustable stitch length Change stitch density for standard overlocking, gathering, rolled hems and decorative techniques. 06 Adjustable cutting width Control how much fabric is removed so the thread wraps neatly around the newly cut edge. 07 Movable upper knife Disengage the upper knife for flatlocking and techniques where the fabric should not be trimmed. 08 Convertible free arm Remove the flat-bed section to overlock cuffs, sleeves and other narrow tubular areas. 6 Versatile stitch configurations Move from strong garment seams to lightweight edge finishing, decorative flatlocking and narrow rolled hems. Choose the right finish for the project 2, 3 and 4-thread overlocking The number of threads and needles used affects seam strength, edge coverage, flexibility and thread consumption. The supplied 2-thread spreader expands the available stitch range without requiring another attachment. Four-thread safety overlock Three-thread wide overlock Three-thread narrow overlock Three-thread rolled hem Two-thread overlock Two-thread rolled edge Professional finishing options What each overlock configuration is designed to do Four-thread overlock The strongest standard configuration for simultaneously constructing and finishing stretch or woven seams. Three-thread wide overlock Provides broad edge coverage for medium-weight materials and decorative finishing. Three-thread narrow overlock Creates a lighter and narrower edge finish while using less thread. Rolled hem Rolls and encloses the raw edge for scarves, napkins, ruffles and fine decorative finishes. Flatlock stitch Opens into a flat decorative seam for sportswear, joining, craft projects and embellishment. Two-thread finishing Uses one needle and one looper thread for lightweight edge finishing and decoration. Control stretching, waving and puckering Fully adjustable differential feed An overlocker uses separate front and rear feed-dog sections. Differential feed changes how quickly those sections move in relation to each other. Increase the setting when knit or bias-cut fabric stretches and becomes wavy as it passes beneath the presser foot. Reduce the setting when lightweight woven fabric puckers or when a deliberately stretched decorative effect is required. Stretch seams Help control rippling on jersey, ribbing, leggings and activewear. Fine fabrics Reduce unwanted puckering on lightweight and silky materials. Gathering Create controlled gathers by increasing differential feed and stitch length. Decorative effects Create stretched lettuce edges where the project requires them. A defining Heavy Duty feature 60% larger cutting knife The cutting system trims the seam allowance immediately before the loopers wrap thread around the edge. Singer’s enlarged knife provides more cutting surface and capacity through thicker fabric combinations. This is particularly useful around fleece seams, sweatshirt fabrics, multiple garment layers and bulky intersections. Suitable applications Fleece Sweatshirt fabrics Garment-weight denim Layered seam allowances Home décor fabrics Regular garment production Balance the fabric edge and thread coverage Adjustable cutting width Cutting width determines how much fabric remains between the newly trimmed edge and the needle stitching. Increase the width when the thread loops pull the edge underneath or cause it to curl. Reduce the width when the loops extend beyond the fabric edge and appear loose or unsupported. Cleaner thread wrapping Improved edge coverage Adaptable to different fabric weights Useful for rolled hems Helps control edge curling Works with adjustable stitch length Overlock without trimming when required Movable upper knife The upper knife can be disengaged when a technique should form stitching without removing fabric. This is useful for flatlocking, selected decorative applications and sewing along a previously prepared edge. Always keep the project clear of the stationary lower knife and follow the instruction manual when disengaging or re-engaging the upper knife. Fast narrow-edge finishing Built-in rolled-hem conversion Move the stitch-finger lever to change from standard overlocking to a narrow rolled-edge configuration. The fabric edge rolls as the machine trims and encloses it with thread, producing a compact decorative finish. Adjust the stitch length, cutting width and tension to suit the fabric and amount of thread coverage required. No separate stitch plate Scarves Napkins Ruffles Sheer fabrics Decorative edges 1,300 Stitches per minute High-speed overlocking completes long seams, repeated garment construction and edge finishing efficiently. Clearly marked threading paths Colour-coded threading system Each needle and looper thread follows its own colour-coded path from the spool stand through the tension dial and internal guides. The threading chart inside the front cover provides a reference while the machine is open. Correct threading order is essential. Thread the upper looper, lower looper and needles in the sequence shown in the manual whenever the machine is fully rethreaded. Colour-coded tension dials Colour-matched thread paths Internal threading chart Lay-in tension guides Tweezers included Four-spool telescopic thread stand Bright visibility around the sewing area Dual LED lighting Two LED lights illuminate the needle, presser-foot and cutting area while remaining cool during use. Improved visibility helps when aligning fabric edges, checking seam allowances and monitoring stitch formation. Additional clearance for layered projects Extra-high presser-foot lift Raise the presser-foot lever beyond its normal lifted position to create extra room beneath the foot. This makes it easier to position fleece, thicker garment seams and bulky intersections before beginning to overlock. Extra-high lift provides more positioning clearance. It does not convert the 14HD854 into an industrial overlocker or increase the maximum stitch formation thickness. Reach smaller tubular areas Convertible free arm Remove the flat-bed storage section to reveal the narrower free-arm area. Sleeves, cuffs and trouser openings can pass around the arm instead of being folded or compressed across the full machine bed. Sleeves Cuffs Trouser hems Children’s garments Leggings Narrow circular seams Keep the sewing table tidier Attachable scrap bag included Overlocking naturally creates small strips of trimmed fabric and loose thread. The supplied scrap bag attaches near the cutting area and collects much of this waste before it falls onto the table or floor. Empty it regularly when sewing fleece, lint-producing knits or larger projects. What can you make with the Singer 14HD854? Fast finishing for stretch garments and everyday sewing T-shirts Activewear Leggings Sweatshirts Children’s clothing Woven garments Fleece projects Rolled hems Flatlocking Curtains Alterations Decorative edging Important information before purchasing The Singer 14HD854 is a domestic overlocker. It sews overlock seams, trims seam allowances and finishes raw edges. It does not replace a conventional sewing machine and cannot sew ordinary lockstitches, standard straight stitching, zigzags, buttonholes or zip applications in the same way. It is not a coverstitch machine and does not create parallel twin-needle cover hems like those commonly seen on T-shirt sleeves and lower hems. The machine uses conventional colour-coded threading. It does not have air threading or automatic tension. Thread tension, stitch length, cutting width and differential feed are adjusted manually. Although marketed as Heavy Duty, it remains a domestic overlocker and is not designed for continuous industrial production.

It uses colour-coded threading and includes a threading diagram inside the front cover. Overlockers require the correct threading sequence, so reading the manual and practising with four different thread colours is recommended. Why is the 14HD854 described as Heavy Duty? It has a metal internal frame, high-output motor, enlarged cutting knife, extra-high presser-foot lift and high-speed operation. It remains a domestic machine rather than an industrial overlocker. Can it sew with two, three and four threads? Yes. It supports 2, 3 and 4-thread configurations, with the supplied spreader used for two-thread stitches. What is the benefit of the larger cutting knife? The larger knife provides additional cutting capacity through thicker fabrics, layered seam allowances and bulky garment intersections. Does it sew rolled hems? Yes. The built-in stitch-finger lever converts the machine for rolled hems without requiring a different stitch plate. Does it have differential feed? Yes. Differential feed helps control waving in stretch fabrics, puckering in lightweight fabrics and can also create gathering or decorative stretching. Can it sew stretch fabric? Yes. Four-thread overlocking and differential feed make it particularly useful for jersey, ribbing, leggings, activewear and other stretch garments. Can it sew fleece and denim? It can overlock fleece, sweatshirt fabrics and ordinary garment-weight denim when correctly threaded and fitted with suitable needles. It is not intended for continuous industrial production or extremely heavy materials. Does it cut the fabric while sewing? Yes. The upper and lower knives trim the seam allowance immediately before the loopers wrap thread around the edge. Can the upper knife be switched off? Yes. The upper knife can be moved out of the cutting position for flatlocking and techniques where trimming is not required. Does it have a free arm? Yes. Remove the storage compartment to overlock cuffs, sleeves, trouser hems and smaller tubular projects. Does it have air threading? No. It uses conventional colour-coded threading through the tension dials, guides, loopers and needles. Does it replace a normal sewing machine? No. A conventional sewing machine is still required for standard straight stitching, buttonholes, zips, top stitching and many construction techniques. Does it sew coverstitch hems? No. A dedicated coverstitch machine is required for the parallel cover hems commonly seen on T-shirts and activewear. How fast does the Singer 14HD854 sew? It sews at up to approximately 1,300 stitches per minute, with operating speed controlled through the foot pedal. What is the difference between the 14HD854 and SE017? Both offer 2, 3 and 4-thread stitching, differential feed and speeds up to 1,300 stitches per minute. The 14HD854 highlights its 60% larger cutting knife and dual sewing lights, while the SE017 adds a dedicated Easy View LED inside the lower-looper threading area.
