Carbide-Insert Drill Bits
 |
Shown with Carbide Inserts (Sold Separately) |
When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.
Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

Rebar-Cutting Core Drill Bits for Concrete
Threaded-Hub Shank for Rotary Only Drilling
 |
Bits are designed for wet drilling on a drilling rig. To avoid damage to bits and tools, do not use for dry drilling or with portable drills or grinders.
