SKU CH-HASW-1ZE73

4 mm single-flute carbide cutter with up-down spiral for clean compression cuts in wood, acrylic, PVC and density board

  • Product typeRight-Angle Drills

  • Up-down compression cut prevents tear-out on both faces
  • 4 mm shank fits standard CNC collets
  • 22 mm cutting length handles thick panels
  • Tungsten steel carbide resists wear in abrasive boards

Purpose-built carbide cutter for CNC wood

This single-flute spiral mill is made from tungsten steel and sized at 4X22X45mm for use in CNC machinery. It targets operators who need a dedicated up-down compression tool for clean edges on wood board, density board, acrylic and PVC. The cutter is not suited for metalwork or for users requiring multi-flute geometry.

Sustained cutting behaviour in sheet goods

The up-down compound helix pushes chips both upward and downward to reduce tear-out on both faces during prolonged passes. Single-flute geometry provides large chip clearance so the tool runs cooler during extended routing sessions. Carbide construction maintains edge life when cutting abrasive composite boards continuously.

Tungsten steel build with standard shank fit

The blue-coated carbide body resists wear while the plain shank fits common collets without proprietary adapters. One piece per package means replacements are ordered individually rather than in sets. Safety note restricts use to persons aged 18 and over and to industrial cutting applications only.

Questions about this item

How much heat does the 4X22X45mm carbide mill cutter generate during continuous CNC routing?

The solid tungsten steel body dissipates heat efficiently during extended cutting of acrylic, PVC, density board and wood, reducing thermal buildup on the tool and workpiece.

What shank size must my CNC router collet accept to hold this 4 mm diameter cutter?

The cutter has a 4 mm shank, so your machine needs a 4 mm collet or an appropriate adapter for secure clamping.

Will the up-down spiral flute work cleanly on the older density board sheets I already have in stock?

Yes, the compound single flute design shears fibres in both directions, giving clean edges on existing density board, wood board, acrylic and PVC without tear-out.
