## Description

Titanium Nitride Coating resists heat and friction, extending the cutting edge life up to 6 times that of other high-speed step drill bits. Made from premium high-speed steel for increased durability. 135-degree split-point tip starts drilling immediately with less force and eliminates "walking" across the work surface.

Review: Well made. Works great - Cut hole in metal bracket on fence. No problem
Review: Pleasantly surprised ! - I wasnt sure if these would be the same quality as store bought ones, or some knock offs, but they seem great! I have used them on steel, and they seem the same good quality as the irwin ones Ive bought at the store. So a good deal on a assortment. I will purchase another one. Maybe a couple more :)

## Customer Reviews

### ⭐⭐⭐⭐⭐ Well made. Works great
*by B***Y on October 19, 2024*

Cut hole in metal bracket on fence. No problem

### ⭐⭐⭐⭐⭐ Pleasantly surprised !
*by C***D on September 8, 2023*

I wasnt sure if these would be the same quality as store bought ones, or some knock offs, but they seem great! I have used them on steel, and they seem the same good quality as the irwin ones Ive bought at the store. So a good deal on a assortment. I will purchase another one. Maybe a couple more :)

### ⭐⭐⭐⭐⭐ Best drill bits I've ever owned - they last forever. Duplicate small common bits is great.
*by D***R on August 17, 2016*

I got a set of these years back. I have never had to sharpen them (and I built theater sets and props, and did a lot of drilling). They are the best drill bits I have ever owned (and, word to the wise: don't buy DeWalt bits). The common (but small) 1/16, 3/32, and 1/8 sizes are often lost or damaged - this set has an extra of these sizes.
