Product Overview

The Milwaukee 48-89-9100 1/8 in. -1/2 in. x 1/32 in. 13 Hole Step Drill Bits far surpasses the competition. With our single cutting edge design, you will have more control and a cleaner finish. Made of high speed steel, these new step drill bits are durable and designed to drill through most metals. The black oxide finish prevents corrosion and has great capacity to work with drilling lubricants. The new speed start tip prevents bit walking and allows faster penetration. With laser etched markings you will always know your hole sizes. No guess work. Finally, the 1/4 in. hex shank allows for fast bit change in impact drivers and sure grip in chucks.

  • Single cutting edge provides true round holes every time
  • High speed steel make-up is ideal for cutting into stainless steel, aluminum, brass, copper, plastic and more
  • Black oxide finish resists corrosion for longer life
  • Speed start tip starts fast and reduces the risk of bit walking
  • Laser etched markings for fast, easy hole size identification

Customer Reviews

1/8 in. -1/2 in. x 1/32 in. 13-Hole Step Drill Bit is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Strong and sharp! This bit is super sharp and does not slip on chuck when drilling. If you have ever been in the middle of a job and had to stop to tighten your chuck, you know what a pain it can be. This bit along with the others I have purchased are worth every penny.
