CNC Router Cutter Set
This five-piece set supplies DLC-coated carbide spiral cutters built for CNC routers. Each cutter measures 4 by 17 millimetres and uses an up-and-down compression geometry. The tools target woodworkers and fabricators who need clean edges on plywood, density board, solid wood and particleboard.
Upgrade From Single-Flute Bits
The two-flute compression design replaces single-flute or straight-flute cutters that tend to tear the top or bottom surface of laminated sheet stock. The jump is worth it when finish quality on both faces matters more than maximum material-removal rate.
ER-Collet Installation
The shank fits standard ER collets used on most hobby and light-industrial CNC spindles. Tighten the collet nut to the manufacturer’s torque spec and verify run-out before cutting. The main risk is excessive feed speed, which can chip the DLC coating or snap the carbide at the flute intersection.

Questions about this item
What shank diameter fits the 4×17 mm cutters?
The cutters have a 4 mm shank, so the collet or chuck must accept a 4 mm shank for a secure hold.
How should the DLC up/down compression flutes be oriented during installation?
Insert the tool fully into the collet, tighten evenly, and ensure the up-cut and down-cut flutes engage the workpiece simultaneously to prevent tear-out on both faces.
When do the tungsten-steel cutters need replacement?
Replace them when the DLC coating shows visible wear, cutting edges become dull, or cut quality drops on wood, plywood, density board, solid wood or particleboard.
