Carbide-tipped rotary hammer. Wave design transmits energy faster. Integral shank provides better power transmissions and lets smaller hammers make larger holes. Dust and debris filter out the bottom, away from hands.
Generates a bit of debris, so be sure to have a water supply nearby.
Carbide-tipped centering bit. Asymmetrical teeth will cut faster and last longer. All-in-one core transmits power directly to the end of the bit. 2-5/8" maximum core size. Drill through concrete effortlessly. Cuts smoothly and quickly. Choice of size.
May take a while to drill through, but it makes very precise cuts.
Tungsten carbide teeth. Integrated pilot bit and mandrel. Ejector hole. Works with Bosch Speedcore SDS-pls pilot bits and extensions. Quality construction. Quick and easy to use.
Can be challenging to remove from the center drill bit assembly.
Hollow core bit is suited for modern rotary hammers. Roof-shaped guide teeth improve tool alignment and stability. Flat hammer teeth are efficient in base. Long lasting. Choice of sizes.
You stick the drill bit in place rather than screwing in securely, so it can drop out inconveniently.
Wave design effectively transfers energy to bit. Integral shank for better transmission. 1-piece design to maximize durability and working life. Intended for drilling masonry and concrete. Works either wet or dry.
Designed only for use with spline drives. Cannot use with standard 3-jaw chuck drives.

Rotary hammers are indispensable tools for making holes in tough materials. Unlike regular drills, rotary hammers use a rotating bit that hammers in and out of concrete using a piston. This allows the tool to make a much larger hole more quickly. Because of the greater stresses involved, a good core bit is required to keep the tool working. The design and durability of the bit are important. A carbide-tipped core bit, for example, will stand up to the abuse concrete can dish out. Pay attention to the design of the shank to make sure it is compatible with your rotary hammer chuck.
