10-piece Tungsten steel router bit set
This set contains ten solid carbide router bits with two flutes each. The shank diameter is 4 mm, the cutting length is 42 mm and the overall length is 70 mm. They are manufactured from Tungsten steel for CNC milling and engraving work.
For CNC operators cutting wood, acrylic, PVC.
The bits suit users who need a multi-piece replacement set for precision engraving and fine cutting on softer materials. Buyers who require larger diameters, different flute geometries or tooling rated for ferrous metals should look elsewhere.
Supplied in a single box of ten pieces
The pack delivers a ready-to-use quantity that reduces downtime when a cutter wears out. No additional software, collets or mounting hardware are included, so the operator must provide compatible tool holders and safety equipment.

Questions about this item
What collet size do I need for the 4 mm shank on these router bits?
These bits have a 4 mm shank, so you need a 4 mm collet or an adapter that accepts 4 mm shanks in your CNC router or spindle.
Can I run these tungsten-steel bits in the same CNC machine I use for high-speed steel cutters?
Yes, they fit any machine that takes a 4 mm shank; just lower the feed rate and spindle speed compared with high-speed steel to avoid overheating the carbide.
How do I know the bits are cutting correctly after I install them?
You should see clean edges with no burning or tear-out on wood, plywood, acrylic, PVC, nylon or resin, and the 42 mm cutting length should engage fully without vibration.
