Description

Twist drills open the small precise holes that bench work depends on, in gold, silver, copper and brass. These are High Speed Steel (HSS) drills in wire-gauge sizes #80 to #50, sold in packs of 10 of one size. The shank diameter matches the drill diameter across the range, so they hold in adjustable chuck handpieces, drill presses and adapter chucks for collet-style quick-change handpieces.

The range runs from the finest #80 (0.343 mm / 0.0135") up to #50 (1.778 mm / 0.0700"), covering 31 individual wire-gauge sizes.

Features

  • High Speed Steel (HSS) construction for durability in non-ferrous metals
  • Straight shank, shank diameter matches drill diameter throughout the range
  • Holds in adjustable chuck handpieces, drill presses and adapter chucks for collet-style quick-change handpieces
  • 31 individual sizes from #80 to #50
  • Sold in packs of 10 drills per size

We do not have that exactly and we do not offer it. We have something close https://www.ottofrei.com/products/hss-twist-drill-kit-220pc-75-58-0-53mm-1-07mm-plastic-box?_pos=3&_sid=5742978fa&_ss=r&_fid=c91f7a813 see part # 128.507. You can buy the missing sizes individually and buy a the same plastic box to have the other sizes not included to complete your set.
