10-piece carbide router bit set

This set contains ten two-flute straight bits made from tungsten steel for CNC machining. Each bit has a 3.175 mm shank, 1.5 mm cutting diameter, 12 mm flute length and 38 mm overall length. They are supplied new in a single box.

For engraving acrylic, PVC, nylon, resin.

The fine cutting geometry suits detailed engraving and light profiling in softer materials. The 1.5 mm diameter limits material removal rate, so the set is not intended for heavy stock removal or large-diameter profiling. Users needing wider cuts or deeper passes should choose larger tooling.

1.5 mm cutting diameter decides suitability

This dimension determines the minimum feature size and the maximum step-over for a given finish. If the project requires finer detail or wider cuts, a different diameter is required.

Questions about this item

How deep can the 12 mm flute cut before heat becomes the limiting factor?

The 12 mm flute length sets the maximum depth per pass; sustained cutting at full depth in dense material will raise temperature until the tungsten-steel edge dulls.

Does the solid-carbide body stay cool and quiet during continuous CNC routing?

Solid carbide conducts heat well but has no internal cooling; expect noticeable warmth and standard high-speed routing noise after prolonged sessions.

What shank size must my collet accept for these 3.175 mm bits?

The 3.175 mm shank requires a matching 3.175 mm (1/8 inch) collet or chuck; verify your spindle or router accepts that diameter.
