Irwin Drill Bit 5/16 In. x 4 In. x 6 In. Masonry
This IRWIN® 5/16-Inch x 4-Inch x 6-Inch Rotary Percussion-Straight Shank Masonry Drill Bit withstands high-speed drilling for efficient work in bricks and blocks. It fits three-jaw rotary hammer chucks and Jacobs chucks, so you can use it with many common tools. This Irwin masonry drill bit features a hardened steel shaft that resists warping from pressure. Its durable finish protects the shape of the spiral from heat, and it withstands ongoing friction without losing its shape. This double tempered finish also protects the straight shank drill bit from pressure, so it doesn’t shatter when the rotary hammer bit encounters resistance. A flute spiral goes up the entire shank and drives dust away from the tip while you drill; this increases the efficiency of your tool and creates holes in masonry as quickly as possible.
