Precision CNC Router Bit for Composite Materials
The YINGHUA 3.175X28X50mm carbide mill cutter is designed for CNC machinery operators who need clean edges on layered boards. Its up-down spiral geometry compresses the top and bottom surfaces during the cut to reduce tear-out on materials such as acrylic, PVC, density board and wood board. The single-flute design evacuates chips efficiently while the tungsten steel body maintains sharpness over extended production runs.
Upgrade from Standard Straight Flute Bits
This cutter replaces conventional straight-flute or single-direction spiral bits when delamination on double-sided laminates becomes unacceptable. The compound up-down action is worth the change when finish quality on both faces of the workpiece matters more than maximum feed speed. It is not suited for heavy hogging in thick solid timber where a multi-flute roughing tool would clear material faster.
Limits of the 3.175 mm Shank Interface
The 3.175 mm shank diameter restricts use to collets or chucks that accept this exact size; it will not fit standard 6 mm or 1/4 inch holders without an adapter. The 28 mm cutting length and 50 mm overall length define the maximum depth of cut and tool reach, so deep pockets or tall workpieces may require a longer tool. The tool is rated for industrial cutting only and must not be used by anyone under 18 years of age.

Questions about this item
What shank diameter does the 3.175 mm carbide cutter need in the collet?
The cutter has a 3.175 mm shank, so the collet or chuck must accept that exact diameter.
How should the up-down single-flute bit be oriented when installing it in a CNC router?
Insert the bit fully into the collet, tighten securely, and ensure the up-cut and down-cut flutes are aligned with the spindle rotation direction for proper chip evacuation.
When will the tungsten-steel cutting edges need replacement during acrylic or wood board work?
Replace the cutter when the carbide edges show visible dulling, chipping, or when cut quality on acrylic, PVC, density board or wood board degrades noticeably.
