Product Overview
The Richard JRP-18 masonry drill bit is designed for professional use in 3-jaw chuck drills, ideal for creating holes in hard materials such as brick, concrete, cinder block, and stone. This straight shank drill bit features a diamond ground tungsten carbide tip, which is copper brazed for durability and heat resistant up to 1,800 degrees Fahrenheit. Manufactured according to ANSI standards, it incorporates a 15-degree negative grind to minimize carbide chipping during use. It has a 5/16 inch cutting diameter, a 4-3/4 inch overall length, and a 5/16 inch straight shank diameter.
