Precision CNC Router Bit for Compression Cutting
The YINGHUA 3.175X17X38mm carbide mill cutter is a single-flute up-down spiral tool designed for CNC machinery. Its compound geometry performs compression cuts that reduce tear-out on both faces of the workpiece. It suits woodworkers and fabricators processing acrylic, PVC, density board and wood board. The tool is supplied new as a single piece for industrial cutting applications only.
Sustained Cutting Behaviour in Sheet Materials
The up-down flute configuration shears fibres in opposite directions during a continuous pass, which stabilises the cut through the full 17 mm cutting length. This geometry resists the deflection that can occur when a single-direction flute pulls or pushes material over a long engagement. Carbide construction maintains edge integrity through repeated contact with abrasive composites such as density board. The design targets consistent finish quality across the full depth of cut.
Diameter and Shank Constraints for Tool Holders
The 3.175 mm shank diameter determines collet or chuck compatibility and cannot be adapted to larger holder bores without a precision sleeve. Overall length of 38 mm limits reach inside deep pockets or fixtures, so the tool suits shallow profiling and through-cuts rather than deep cavity work. The single flute evacuates chips in a single channel, which demands adequate feed rates to prevent re-cutting. Users under 18 years must not handle this bladed product.

Questions about this item
How much heat does the 3.175 mm carbide cutter generate during continuous CNC routing?
The tungsten-steel body dissipates heat efficiently, but sustained cuts in dense board will warm the shank; use coolant or air blast for long runs.
What collet or holder does the 3.175 mm shank require to run in my machine?
A 3.175 mm ER collet or matching shrink-fit holder is needed; the shank is ground to that exact diameter.
Will this up-cut/down-cut bit work safely on my older CNC router running at lower spindle speeds?
Yes — the single-flute geometry reduces load, so it cuts cleanly at modest RPMs typical of older routers.
