This Compression Bit combines both up-cut and down-cut flutes to deliver chip-free edges on the top and bottom surfaces of your workpiece. With a cutting size of 8mm × 25mm, it’s engineered for CNC routing, joinery, and furniture production. By pulling and pushing chips toward the centre, it leaves crisp edges on plywood, MDF, solid timber, and laminates. Key benefits Chip-free edges — up-cut and down-cut sections protect both faces for cleaner results. DLC or nano coating improves lubricity and heat resistance for longer tool life. 3-flute finish & accuracy — stable cutting and smoother walls where finish matters. Ideal for CNC routing of wood, MDF, plywood, laminates and non-abrasive composites. Built for tougher applications in hardwoods, plywood and plastics where ordinary bits dull quickly. .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 8mm Cut Length 25mm Shank (Collet Size) 8mm Overall Length 38mm Flutes 3 Coating Nano (NaCO) Nano coating for higher feed rates An advanced nano coating enhances heat resistance and lubricity, allowing higher feed rates while prolonging tool life. This keeps the cut cleaner and more consistent, especially in longer production runs and tougher materials. Reduced friction means lower heat build-up and slower edge wear, so the bit stays sharp longer. Versatility and benefits Thanks to its 3-flute geometry, this bit excels at dados, grooves, slots, mortises, and edge trimming. It’s a favourite among cabinetmakers, sign makers, and CNC hobbyists for cutting hardwoods, laminates, veneers and sheet goods, and can be used on thin aluminium where suitable. Whether you’re creating pockets, trimming laminates, or nesting parts, this compression bit improves productivity and finish quality.
