Carbide Tipped Drill Bits

Mechanical and Adhesive masonry anchors require a pre-drilled hole. Our Masonry Drills are an excellent choice for preparing the anchoring hole.

Specifically for use in masonry drilling, these drills are made of high grade heat treated alloy tool steel for maximum life. They feature a slotted drive shaft (SDS) type chuck, a copper brazed carbide tip, TurboT flute design, and meet ANSI standards. Cutting heads available in standard and the QuartoT head which has four cutting faces which reduce vibration up to 60% and noise up to 30%. The QuatroT head also increases the bit's life by 30% while drilling speed is improved by 15%. It 'spots' holes more accurately and produces rounder holes than the standard cutting head. These bits can be used with most other manufacturers drills. A cross reference table is available. See the correct table below for available sizes of drills with a Standard Cutting Head and the QuatroT Cutting Head.
