10-piece carbide router bit set

This set supplies ten solid-carbide two-flute straight bits sized 3.175X3.175X22X45 for CNC routing. They are intended for engraving and cutting acrylic, PVC, nylon, resin, wood and plywood. The tungsten steel construction suits light industrial workshops and serious hobbyists who need repeatable cuts. Buyers who need larger diameters or different flute geometries should look elsewhere.

Sustained cutting performance

Tungsten steel holds its edge through extended passes in abrasive materials such as plywood and resin. The two-flute design clears chips continuously, reducing heat build-up during long runs. Cutting fine detail in acrylic or PVC remains consistent without frequent tool changes. The bits are not rated for hazardous or non-listed materials.

Installation and common issues

Each bit has a 3.175 mm shank that fits standard collets of that size; no adapters are included. Secure the collet firmly to prevent run-out, which is the main cause of premature wear. The blades are sharp and the product is restricted to users aged 18 and over. Improper feed rates or cutting unsupported materials often lead to chipping or breakage.

Questions about this item

How much heat or noise does the 3.175 mm shank generate during long CNC runs?

The solid carbide bits run cool and quiet in wood, acrylic, PVC, nylon, resin and plywood because the two-flute design clears chips efficiently, reducing friction and motor load.

What collet or chuck must I already have to hold the 3.175 mm shank?

You need a collet or chuck that accepts a 3.175 mm shank; the 10-piece set fits standard CNC routers and engraving spindles with that bore size.

Will these 22 mm cutting-length bits work on the same materials as my older high-speed steel router bits?

Yes, they cut the same materials — wood, plywood, acrylic, PVC, nylon and resin — but the tungsten steel stays sharp longer, giving cleaner edges on fine engraving jobs.
