10-piece carbide router bit set

This set contains ten two-flute solid carbide router bits sized 3.175X2.5X12X38 for CNC machining. They are intended for engraving and cutting acrylic, PVC, nylon, resin, wood and plywood. The tungsten steel construction supports precise cutting in a workshop environment. Industrial use only; not for anyone under 18 years old.

Replaces worn CNC cutters

The bits serve as direct replacements for dull or damaged two-flute carbide cutters in a CNC machine. The jump is worth it when existing bits no longer produce clean edges in the listed materials. A fresh set restores cutting accuracy without changing toolpaths or holder specifications.

Limited to compatible collets and materials

The 3.175 mm shank diameter requires a matching collet or chuck; other holder sizes will not secure the bit. The cutting geometry suits the specified plastics and woods but is not rated for metals, stone or hazardous materials. Operation must remain within the machine's rated speed and feed envelope.

Questions about this item

What shank diameter do the YINGHUA router bits need in a collet or chuck?

Each bit has a 3.175 mm shank, so the collet or chuck must accept that exact diameter for a secure grip.

How do I install these carbide bits without snapping the 12 mm cutting section?

Tighten the collet on the 3.175 mm shank only, keep the 12 mm flute length clear of the holder, and use light feed rates when starting the cut.

When should I replace a bit from this 10-piece tungsten-steel set?

Replace a bit when the two-flute edges show visible wear, chipping, or when cuts in wood, acrylic or PVC become rough or burnished.
