A medium grit diamond sintered burr with a tapered profile and a flat 0.75mm end, designed for precise engraving, shaping and smoothing in glass, stone, hard metals, ceramics and other hard materials. The 3mm widest point gives you useful surface coverage, while the narrow flat tip offers more control than a larger cone burr.

Best for: 

• Glass engraving and carving
• Shaping and refining hard metals
• Smoothing narrow grooves and channels
• Stone, ceramic and lapidary work
• Controlled material removal where a broader cone burr is too large

Key features:

• Medium grit (170#)
• 3mm at the widest point
• Tapers down to a 0.75mm flat end
• 2.35mm shank (3/32")
• Suitable for use with rotary tools, pendant drills and micromotors

If you need a broader, more general-purpose flat end taper burr, see our Diamond Sintered Burrs Flat End Taper. If you want a larger cone shape for more aggressive shaping, see our Diamond Sintered Burrs Cone. This 3mm version is better suited to finer, more controlled work where accuracy matters.
