 PB SERIES  - B TAPER MASONRY PERCUSSION
B & A Manufacturing's Taper drill bits are made to fit our high quality adapters. The smaller "A" taper shanks are intended for bit diameters from 3/16" to 7/8". "B" taper shanks are most effective in large capacity rotary percussion hammers. They are available in sizes from 7/16" to 1-1/8" diameters. B & A Taper drill bits are made from high grade steel that is heat treated and tempered for the longest drilling life possible. The asymmetrical spiral flute, B & As "Ultra Flute", allows for efficient dust removal and cooler operating temperatures.
