BOSCHHAR7947 BITS/DRILL HEX SHANK 3/16

Bosch Hex Shank Hammer Drill Masonry Bits deliver 4X life vs. standard masonry bits, and have been redesigned with hex shanks for use in hammer drills and impact drivers. These bits feature asymmetric diamond-ground carbide tips, which deliver fast drilling and longer bit life in hammer drills and impact drivers. The tips are designed for precise starts and less bit walking. The bit heads are manufactured with exclusive Bosch-made carbide. They have milled U-flutes with deep-cut spirals for fast drilling in block, masonry and concrete. The hex shank provides aggressive gripping power.
