This Compression Bit combines both up-cut and down-cut flute geometry to deliver continuous burr-free edges on the top and bottom surfaces of your workpiece, efficiently remove swa rf for easy clean-up and to run fast! Key benefits Burr-free Edges thanks to Up-cut and down-cut flutes Extended tool life with DLC coating. 1-flute design provides a smooth finish, stable cutting, and reliable chip extraction Ideal for CNC routing of ACM, wood, MDF, plywood, laminates and non-abrasive composites. Special geometry extracts chips for easy cleanup. Best suited for large panels and big shapes where vacuum hold-down is sufficient. Cuts panels with Pre-applied Vinyl beautifully, no furry edges. Small 4mm Diameter, perfect for tight corners Engineered for CNC routing of ACM panels, joinery and cabinet making when cutting plywood, MDF, solid timber, laminates and non-abrasive composites. .atlas-spec-table-wrap { padding: 5px; margin: 30px 0 0; border: 1px solid #000; border-radius: 16px; overflow: hidden; background: #161616; box-shadow: inset 0px 1px 2px rgba(255,255,255,0.5), inset 0px 1px 2px rgba(255,255,255,0.5), 5px 8px 10px rgba(0,0,0,0.5), 0 0px 1px rgba(0,0,0,0.5); } .atlas-spec-table { width: 100%; border-collapse: separate; border-spacing: 0; border: 0; margin: 0; background: transparent; } .atlas-spec-table th { background: #dca101; color: #000000; text-align: left; padding: 14px 16px; font-size: 14px; font-weight: 800; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; border-top-left-radius: 12px; border-right: 1px solid rgba(0,0,0,0.2); } .atlas-spec-table td { padding: 14px 16px; border-top: 1px solid rgba(255,255,255,0.08); } .atlas-spec-table td:first-child { width: 42%; border-right: 1px solid rgba(255,255,255,0.08); color: #f2f2f2; font-weight: bold; } .atlas-spec-table td:last-child { color: #d6d6d6; } .atlas-spec-table tbody tr:nth-child(odd) td { background: #1f1f1f; } .atlas-spec-table tbody tr:nth-child(even) td { background: #161616; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; } .atlas-spec-table th:last-child { border-top-right-radius: 12px; } Spec Result Diameter 4mm Cut Length 17mm Shank (Collet Size) 4mm Overall Length 38mm Flutes 1 Coating DLC (Diamond-Like Coating) DLC coating for low-friction cutting A diamond-like carbon (DLC) coating provides an exceptionally hard, low-friction surface that prevents aluminium chips from sticking to the tool. This anti-stick property improves chip removal and reduces heat build-up, making the bit ideal for machining ACM, Woods and composite materials. Reduced chip welding means cleaner edges, lower heat, and more consistent finishes over long runs. Versatility and benefits Thanks to its 1-flute compression geometry, this bit excels at dados, grooves, slots, mortises, edge trimming and cutting panels with Vinyl pre-applied. It’s a favourite among sign makers cabinetmakers, and CNC hobbyists for cutting ACM, laminates, veneers and MDF. Whether you’re creating pockets, trimming laminates or nesting parts, this compression bit improves productivity. Show more
