EFFICIENT: The Bosch SDS-max carbide-tipped rotary hammer core bit features an effective wave design to transfer energy for up to 40 percent speedier drilling versus other bit designs

POWER: With an integral shank, the HC8575 offers better power transmission and is designed to allow smaller hammers to drill larger holes

VERSATILE: This core bit is versatile in application with materials including concrete, brick, and block

INNOVATIVE: Bosch’s unique, optimized flute design reduces bit stress when drilling, keep the bit running cooler, and for fast dust removal.

PRECISION: Featuring a harder diamond ground carbide tip that’s tougher, more resistant, and durable under heavy loads. This drill bit set allows for precise starts in materials such as tile and hard stone. The centric tip’s optimal hole geometry provides rounder holes.

LONGEVITY: With optimized braze and a specialized hardening process, these bits provide a long life. The robust head is ideal for high impact applications.
