Carbide End Mill Set
This set contains five carbide end mill bits designed for compression cutting in wood, plywood, density board, solid wood and particleboard. The up-and-down spiral geometry reduces tear-out on both faces of the workpiece. They are intended for CNC machinery users who need clean edges on double-sided materials. Not suited for metalworking or general-purpose twist drilling.
Shank Fit and Toolholding
Each bit has a 4 mm shank that must match your collet or tool holder exactly; an undersized collet will cause run-out and premature wear. The 25 mm cutting length requires sufficient Z-axis travel and rigid clamping to prevent vibration. Over-tightening the collet nut can fracture the tungsten steel shank, so apply firm, even pressure only. Bits are supplied in single independent packages for protection.
Machine Compatibility Check
Verify that your CNC spindle accepts 4 mm shanks and provides enough clearance for the 45 mm overall length. Confirm the machine’s feed and speed range suits carbide tooling in wood composites to avoid burning or chipping. Ensure your dust extraction can handle fine composite dust, which is a health hazard. The product is restricted to users aged 18 and over for industrial cutting only.

Questions about this item
How can I verify the up/down cut action is performing correctly on my CNC after installing these 4 mm shank bits?
Run a test cut in scrap plywood or density board; a clean top and bottom edge with no tear-out confirms the compression geometry is working as intended.
What exactly ships in the package and what must I obtain separately?
The box holds five individually wrapped 4x25x45 mm two-flute tungsten-steel compression cutters; collets, tool holders or dust extraction are not included.
With only the 4x25x45 mm size offered, how do I decide if this set suits my job?
Choose this set when you need a 4 mm shank, 25 mm cutting length and 45 mm overall length for compression cuts in wood, plywood, density board, solid wood or particleboard.
