Precision CNC End Mill
This carbide milling cutter is designed for CNC machinery requiring precise compression cuts. The two-flute up-and-down spiral geometry reduces tear-out on both faces of the workpiece. It suits woodworkers and fabricators processing solid wood, plywood, particleboard and density board. Buyers needing high-volume production tooling or specialised metal-cutting profiles should look elsewhere.
DLC Coating and Shank Fit
A diamond-like carbon coating covers the tungsten steel body to resist wear and heat buildup during extended routing sessions. The 4 mm shank fits standard collets without adapters, allowing quick tool changes on compatible routers. The single-piece packaging protects the cutting edges from contact damage during storage. Shops using non-standard collet sizes will need separate holders.
Thermal Behaviour in Routing
The DLC surface lowers friction so the tool runs cooler when cutting dense panels at typical feed rates. Reduced heat means less resin buildup on the flutes and quieter operation through hard knots. Carbide construction maintains edge integrity through repeated plunges without excessive power draw from the spindle motor. Operators should still monitor chip evacuation to prevent localised overheating.

Questions about this item
What does the 17 mm flute length limit in a single pass?
The 17 mm flute length sets the maximum depth of cut per pass; deeper slots require multiple passes.
Will the 45 mm overall length fit my collet and clear the workpiece?
The 45 mm overall length needs a collet that grips the shank and enough Z-travel so the cutter clears the workpiece and fixture.
How do I install the up-down cutter without snapping the carbide?
Tighten the collet on the shank only — never on the flutes — and use a torque wrench to the holder’s spec.
