10-piece carbide router bit set
This set contains ten solid tungsten-steel router bits with a two-flute straight-slot design. Each bit has a 3.175 mm shank, a 2.5 mm cutting diameter and a 17 mm cutting length within a 38 mm overall length. The pack is intended for CNC machinery used in engraving and cutting acrylic, PVC, nylon, resin, wood and plywood.
Replaces worn or single-flute bits
The two-flute geometry clears chips more efficiently than single-flute cutters, reducing heat build-up and improving edge finish on soft plastics and wood. Upgrading is worthwhile when existing bits show chatter, burning or reduced dimensional accuracy on fine detail work.
Limited to 3.175 mm shank machines
The fixed shank diameter restricts use to collets or ER adapters that accept 3.175 mm. The 2.5 mm cutting diameter and 17 mm flute length limit depth of cut and material thickness in a single pass. Not suitable for heavy stock removal, metals or applications requiring larger diameters or longer reach.

Questions about this item
What shank diameter fits the 3.175 mm bits in this 10-piece set?
The shank measures 3.175 mm, so use a collet or chuck sized for that exact diameter.
How deep should the 17 mm flute length be seated in the collet for safe operation?
Insert the bit until the flute starts just beyond the collet face, leaving the full 17 mm cutting length exposed.
When should the tungsten-steel cutters be replaced during acrylic or wood routing?
Replace them when edges dull, chips appear on the workpiece, or feed resistance increases noticeably.
