Masonry drill bit DeWalt DT8922 — 8 mm, for rotary hammer, 1 pc

DeWalt DT8922 masonry drill bit, 8 mm diameter, is designed for use with rotary hammers to drill into concrete, brick and other masonry materials. This single-piece drill bit combines a carbide tip and robust flute geometry to deliver reliable drilling performance on renovation, installation and general construction tasks. The shank is made to fit SDS-plus/percussion chucks so it can be used with a wide range of hammer drills and rotary hammers.

Advantages

The DeWalt DT8922 offers consistent drilling accuracy and long service life due to its wear-resistant carbide tip and reinforced body. Its flute design efficiently removes dust and debris from the hole, reducing friction and heat build-up during extended use. Compatibility with SDS-plus/percussion chucks ensures quick, secure fitting and stable operation in hammer drilling mode.

How to use

Select a rotary hammer with an SDS-plus or compatible percussion chuck and fit the 8 mm DeWalt masonry drill bit securely. Mark the drilling point, set the drill to hammer mode and start at low speed to create a guide point, then increase speed and apply steady pressure without excessive force. Periodically withdraw the bit to clear dust from the hole and prevent clogging. For deeper holes or continuous work, pause occasionally to allow cooling and inspect the bit for wear.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling. For best performance in reinforced concrete, verify drill bit condition before use and replace when the carbide tip shows significant wear. Match drill speed and hammer settings to the material being drilled to prolong bit life and ensure clean holes.
