FAQ

What collet size do these bits need?

All 27 bits share a uniform 1/8" shank, so they fit standard rotary-tool collets without changing holders.

Which shape should I use for fine engraving?

Needle and cone points are best for detail lines; cylinders and flame shapes remove stock faster for carving and shaping.

Can this set be private-labeled?

Yes — custom branding, case colors and tray layouts are part of our OEM program.
