Description

These burs trim and true the inside of a ring band, cutting fast and staying controlled as you clean up the interior after sizing or casting. The cylinder head is sized specifically for inside ring work and seats solidly in a 3/32" collet, so the cut feels stable and predictable on a flex shaft or micromotor. Four cutting aggressions, Fine through Extra Coarse, cover every stage of interior ring work, from light refining to heavy stock removal.

Features

  • Cylinder bur profile sized specifically for inside ring trimming and clean-up
  • Mounted on 3/32" shanks for use with standard flex shaft and micromotor handpieces
  • Single head size across all grits for consistent feel when switching cutting aggressions
  • Engineered for rapid metal removal while maintaining smooth, predictable control
  • Choice of four cutting aggressions: Fine, Medium, Coarse, and Extra Coarse
  • Durable carbide construction for extended service life in daily bench use
  • Manufactured in the USA

Otto Frei is by far the best company on the west coast. I got exactly what I needed, good quality as most of their inventory, good life support to set up a new acount, speedy delivery.
Draw back: 5% discount on my next order, but....... only within the next 72 hours. I send a reply to the AI message to take me of the text message routine, explained why, but that was too much for artificial intelligence to comprehend and deal with. So much for that.
Still the best jewelry supply company in the west with great live customer support and no endless waiting for life person to pick up the phone, unlike .... forgot their name , somewhere in the south west.
