Description of Speedbor 1866051 Irwin Tools Drilling
Three cutting spurs for faster, cleaner holes, less breakout and extended drilling life. Full screw-point tip allows bit to self-feed for ease of drilling. Tapered tri-flute design for faster chip ejection and less binding. 1/4" quick-change shank reduces slipping in standard chucks and is compatible with all 1/4" quick-change chucks, including impact drills.
The promotional image has a blue powder coating on the inside of the drill but as you can see in this image this is not the case. trade in goods. I can't say it really makes a difference but not only am I not a fan if the product advertised doesn't match the product received hence -1 star. When it comes to the actual work, I've used this to drill through a wall for an ethernet cable and damn it was efficient. Very pure, very strong, amazing product.
Pros
Three cutting edges for a faster, cleaner hole, less chipping and longer life
