It’s engineered for plywood, MDF/HDF, hardwoods, softwoods, laminates and some plastics, thanks to its up- & down-cut (compression) geometry that prevents fiber tear-out.

Yes. The upper down-cut and lower up-cut flutes shear toward the panel’s core, stabilizing veneers and virtually eliminating top- or bottom-face splintering.

Absolutely—its ¼″ shank fits any trim, plunge or table router that accepts a ¼″ collet, as well as hobby or production CNC machines.

Community users report reliable cuts at 75-100 in/min (1900-2500 mm/min) with routers locked near 18 k RPM, taking 5 mm passes.

Use a high-quality ¼″ precision collet; keep total indicated run-out under 0.0015″ to preserve edge life and cut accuracy.

Solid-carbide bits can be professionally ground, but at this price most users simply replace them once the cut quality degrades. Forum members treat them as consumables.

SpeTool offers downloadable Fusion 360/VCarve tool libraries plus a feeds-and-speeds PDF on their site—import and tweak for your machine.

Keep chipload up: slow RPM or increase feed until you get chips, not dust; use 1-2 flute bits for wood, evacuate chips, and replace dull edges promptly. Experienced CNC users emphasize heat control over ultra-slow passes.

Many makers run ⅔–¾ of bit diameter (≈0.16-0.18 in/4-4.5 mm) per pass in plywood; reduce depth in dense hardwoods.
