“A” Taper drill bits are designed for use in a rotary hammer equipped with an “A” Taper type chuck. The bits meet ANSI standards and can be used to drill in concrete, block, brick and soft stone. “A” Taper drill bits are manufactured from high grade tool steel. The bit is formed with a Turbo flute which quickly removes dust to provide faster drilling into a variety of masonry materials. The carbide insert is copper brazed to provide longer bit life. “A” Taper drill bits can be used in most models of rotary hammer drills with an “A” Taper shank adapter.
