## Long description

DeWalt DT9641-QZ 8 mm x 160 mm drill bit for rotary hammers is a single-piece SDS Plus accessory intended for light-to-medium drilling tasks in masonry materials. The bit is designed to work with compatible rotary hammers, offering an 8 mm cutting diameter and a 160 mm overall length. Weighing approximately 60 g, this compact drill bit is supplied as one piece and serves as a replacement or spare for routine drilling jobs in brick, concrete and similar substrates.
Advantages
The SDS Plus shank provides secure, quick coupling with rotary hammer chucks and reduces wobble during impact drilling. A flute profile helps evacuate dust and debris from the hole for more efficient cutting and longer service life under repeated use. Its compact length and narrow diameter make it suitable where access is limited or when precise small-diameter holes are required.
Suitable for
Drilling holes in brick for anchors and dowels
Creating pilot holes in concrete and masonry
Installing fixtures into stone or block walls
Replacement of worn or broken 8 mm masonry drill bits
Key specifications
Drill diameter: 8 mm
Overall length: 160 mm

How to use
Fit the DeWalt DT9641-QZ into the rotary hammer’s SDS Plus chuck according to the tool manufacturer’s instructions and ensure it locks securely. Select the hammer or rotary mode recommended for masonry, position the tip at the marked drilling point, and apply steady pressure while allowing the tool’s impact action to advance the hole. Withdraw periodically to clear dust if drilling deep holes. Replace the bit if the cutting performance declines or if the tip is damaged.
Usage recommendations
Use appropriate personal protective equipment such as safety goggles, hearing protection and a dust mask when drilling. Match drilling speed and hammer settings to the material hardness and avoid excessive lateral force to prolong bit life.
