Description of πŸ”© Irwin Tools 4935607 Titanium High-Speed Drill Bit

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. Rubber over-molded case has automatic indexing for easy bit access and identification. Removable cartridges are easy to carry to and from worksite.

Slightly crooked until I sharpened them.

Good point, I found the bits surprising when opening the hole. I ended up sharpening them all with a dr. Start right away, maybe a little less aggressively than before.

Pros
  • Molded rubber case features automatic indexing for easy bit access and identification. Removable chucks are easy to carry to and from work
Cons
  • Something different

Great drill bits for power tool parts and accessories

I use these mostly every day (almost all wood actually) and they are great. They are and will remain sharp. Definitely an upgrade from the hardware store ACE drill bit set I used before.

Pros
  • 135 degree split tip bit starts drilling right away with less effort and eliminates "walking" on work surface
Cons
  • Can't remember

Best drills I've ever had - they last forever. Duplicating small shared bits is great.

I received a set of these drills a few years ago. I've never had to sharpen them (and I've built theater sets and props and drilled a lot). These are the best drill bits I've ever had (and a word to the wise: don't buy DeWalt bits). The common (but small) sizes 1/16, 3/32 and 1/8 are often lost or damaged. - This set has an extra size of these sizes.

Pros
  • The titanium nitride coating is heat and abrasion resistant and provides 6 times longer cutting edge life than other high speed step drills
Cons
  • Some faults
