YINGHUA 5pc 3.175x22 DLC Compression End Mill Bits

SKU CH-E45B-EPQK6

Set of five 3.175 mm carbide compression bits with DLC coating for clean cuts in wood and composites

  • Product typeRight-Angle Drills
  • Five-piece set covers multiple routing jobs
  • 175 mm shank fits standard collets
  • 22 mm cutting length handles thick stock
  • DLC coating reduces friction on wood composites
  • Up-down spiral geometry prevents tear-out on both faces

Five-piece carbide compression set

This five-piece set delivers 3.175 mm diameter compression end mills with 22 mm cutting length. Tungsten steel construction and DLC coating resist wear when routing wood, plywood, density board, solid wood and particleboard. The one-flute up-down spiral geometry shears fibres cleanly on both faces.

Tungsten steel with DLC coating

Each cutter is ground from solid tungsten steel and finished with a diamond-like carbon layer that reduces friction and extends edge life. The right-angle shank fits standard collets on CNC routers, so tool changes stay quick and repeatable. Industrial-grade build tolerates continuous production runs without premature dulling.

Check shank fit and age restriction

Verify that your machine accepts 3.175 mm shanks before ordering. The supplier specifies that bladed products are not for anyone under 18 years old and are intended only for industrial cutting applications. Confirm your collet size and safety compliance to avoid delays.

Questions about this item

What does the 3.175 mm shank diameter limit in terms of collet compatibility?

The 3.175 mm shank requires a matching 3.175 mm collet or an ER collet that closes to that exact diameter; larger collets will not grip the tool securely.

What physical clearance does the 22 mm cutting length demand from the workpiece and machine?

The 22 mm cutting length needs at least 22 mm of unobstructed Z-travel below the collet face and a workpiece thick enough to accommodate the full flute engagement without bottoming out.

How should the up-down compression flutes be oriented during installation to avoid tear-out?

Install the bit so the up-cut section enters the material first and the down-cut section follows, compressing chips toward the centre; reversing this pulls fibres up on both faces.
