Product Details

Recommended for Pave Work on Hard Metals

These Busch Fig 4205S short carbide twist drills are made for just one application: Drilling precise holes in hard metals for pave diamond setting. Short drills make sense because the holes drilled are relatively shallow and long drills have a tendency to break due to torsional stress.

These short carbide burs are used by the world’s finest micro-diamond setters who set stones for the world’s greatest jewelry brand names. Developed by a partnership between those parties and Busch of Germany, these drills are the perfect solution for once was a drill breaking nightmare. Use these drills on hard metals such as platinum, high karat white alloys, titanium, steel as well as gold, silver and other alloys. The 2-groove design helps expel material from the hole extending drill life.

Recommend speed for use: 3,000-5,000 rpm. Not for use with glass, ceramics or gemstones. These carbide twist drills are sold by the piece or in a kit of 4.

Kit of 4 includes:
  • BAU128.407  0.70mm
  • BAU128.408  0.80mm
  • BAU128.409  0.90mm
  • BAU128.410  1.00mm

"Shortie" carbide drills

I love these drills, they cut fast and resharpen easily with the diamond Aglio disks. I do wish they were a little longer but then they are more likely to break.
