Changeable-Size SDS-Max-Shank Masonry Core Drill Bits for Rotary Hammers
These bits allow you to switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling large holes. The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers. They cannot be used with SDS-Plus-drive rotary hammers.
Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also known as percussion or impact bits. To achieve maximum drilling depth, break up and remove the core every 4” before drilling deeper.
Drill bits include a pilot drill to make starting holes easier.

Changeable-Size Spline-Shank Masonry Core Drill Bits for Rotary Hammers
These bits allow you to switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling large holes. The shank has 12 splines for use with a spline-drive rotary hammer. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.
Drill bits include a pilot drill to make starting holes easier.

Chip-Clearing Drill Bits for Wood
An open spiral-flute design clears chips quickly, so these bits can bore smooth, deep holes through construction lumber, railroad ties, and utility poles. Also known as pole or ship auger bits.
Black-oxide and nonstick-coated steel drill bits produce less friction than uncoated steel drill bits.
