YINGHUA 4x22x45mm Blue Up-Down Carbide Router Bit

SKU CH-GQA2-09RCT

4 mm shank carbide router bit with up-cut and down-cut spiral for clean compression cuts in wood, acrylic and PVC

  • Product typeRight-Angle Drills
  • Up-down spiral gives clean edges on both faces
  • Single flute clears chips fast in wood and plastic
  • 4 mm shank fits standard CNC collets
  • 22 mm cutting length handles thick panels
  • Tungsten carbide stays sharp through abrasive materials

Application Scope

This carbide router bit is designed for CNC machining of acrylic, PVC, density board and wood board. The up-down spiral geometry compresses material fibres during cutting, reducing tear-out on both faces of the workpiece.

Target Users

Suitable for operators running desktop or benchtop CNC routers who need single-flute clearance in plastics and sheet goods. Not suitable for anyone requiring multi-flute finishes, heavy hogging in solid timber, or tools rated for non-ferrous metal cutting.

Critical Dimension

The cutting diameter is 4 mm, the flute length is 22 mm and the overall length is 45 mm. These three figures determine whether the bit reaches the required depth and clears the workpiece without bottoming out in the collet.

Questions about this item

Will the 4 mm shank generate noticeable heat during long CNC runs?

The solid tungsten-steel body dissipates heat efficiently, and the single-flute up-down geometry clears chips quickly to keep the 22 mm cutting length cool during extended sessions.

What collet or holder do I need for the 4 mm shank?

A standard 4 mm ER collet or shrink-fit holder matches the shank diameter so the bit seats securely in any compatible CNC spindle.

Can I keep using my older 6 mm collet set with this bit?

The 4 mm shank will not fit a 6 mm collet; you would need a 4 mm collet or a reducing sleeve to run it in your existing tooling.
