DeWALT DT9450-QZ drill bit Masonry drill bit

DeWalt DT9450-QZ masonry drill bit for rotary hammers is designed for fast drilling in concrete, brick, stone and other masonry materials. The bit features an SDS‑Max shank and a solid carbide head with two main cutters plus two additional cutting tips; a four‑flute helix evacuates dust and debris to maintain drilling speed. Diameter: 52 mm, length: 570 mm.

Advantages

The solid two‑cutter carbide head combined with two individual cutting tips provides efficient, high‑speed drilling. The four‑flute helix design improves debris removal to keep the hole clean and reduce clogging. An optimized hardened steel shank ensures a secure fit in SDS‑Max rotary hammers and reliable power transmission, lowering the risk of breakage during heavy use.

Usage recommendations

Use appropriate personal protective equipment (eye protection, gloves, hearing protection) and follow the rotary hammer manufacturer’s safety and maintenance instructions. For reinforced concrete, use caution and inspect for rebar; reduce feed pressure when contacting reinforcing steel to avoid bit damage.
