The New SaburrTooth Mini Flame Bur Set comes with 1 each of the Coarse, Fine, and Extra Fine Whisper burrs. These carbide cutters are a little over 1/8" in diameter and about 1/4" long. They have a 1/8" shank to fit most rotary tools. They would work great for getting into areas where other burs might be too large.

Saburr-Tooth burs feature a fast cutting patented carbide coating that is designed to cut cleanly on most materials. They will not load on most materials and are extremely sharp and are very controllable. They are designed for use in tools with speeds of 4000 RPM to 25000 RPM.
