10-Piece Tungsten Steel CNC Router Bit Set

This 10-piece set supplies tungsten steel two-flute straight bits sized 3.175X1.5X6X38 for CNC routing work. The solid carbide cutters handle engraving and cutting in acrylic, PVC, nylon, resin, wood and plywood. They are intended as direct replacements for existing CNC tooling. Each bit is new and delivered in a single box.

Makers Cutting Soft Materials Not Metal

Hobbyists and small-shop operators working with plastics, wood or composites will find these bits match the listed materials. Buyers who need to machine aluminium, steel or other metals should look elsewhere because the specification only covers softer substrates. The age restriction of 18 years also excludes younger users from purchasing or operating the cutters.

Two-Flute Geometry for Chip Clearance

The double-flute design is the critical feature that governs chip evacuation and cut quality in the target materials. With two cutting edges, the bit balances material removal rate and surface finish for the listed plastics and woods. Selecting a different flute count would change both feed behaviour and edge finish.

Questions about this item

Do I need a CNC router with a 3.175 mm collet to run these 10 two-flute bits?

Yes, the 3.175 mm shank diameter requires a matching collet or chuck on your CNC router for secure clamping.

Can I keep using my existing 6 mm shank tooling alongside these 3.175 mm shank bits without changing collets?

No, the 3.175 mm shank size differs from a 6 mm collet, so you must swap to the correct collet when switching between them.

How can I confirm the tungsten-steel cutters are performing correctly after the first test cut in wood or acrylic?

Check for clean edges without tear-out, consistent 1.5 mm cutting width, and no excessive vibration during the pass.
