Milwaukee 48-20-8845 3/4" x 4" x 6" L. Carbide 3-Flat Masonry Drill Bit Germany
3-Flat Secure-Grip hammer/drill bits provide superiority in regards to quality, performance, and longevity of life.
The 3-Flat Secure-Grip shank is designed to fit in all 1/2" 3-jaw hammer/drill chucks and reduces the possibility of the bit spinning in the chuck during heavy torsional loads.
The bits drill faster and last longer than other hammer/drill bits on the market due to their reinforced flute geometry and carbide tip design.
