Drill bit DeWalt DT9509-QZ, 160 mm length, single pack

DeWalt DT9509-QZ drill bit, 160 mm length, single pack is a carbide-tipped masonry bit designed for creating plug, anchor and clearance holes in solid masonry materials. The 160 mm overall length gives sufficient reach for standard anchoring and through-hole work, while the optimized mounting shank ensures secure fit in compatible drill chucks. The solid two-cutter head with individual cutting tips provides steady progress and controlled chip removal when working with concrete, brick, stone and block.

Advantages

The hardened steel body increases resistance to breakage and wear during repetitive drilling in masonry. The optimized mounting shank provides a positive grip and efficient power transmission from the drill to the bit, reducing slippage and improving drilling accuracy. The two cutter head design and carbide cutting tips deliver faster penetration and consistent hole quality in tough substrates.

Suitable for

• Drilling anchor and plug holes in concrete and masonry
• Making clearance holes for bolts and services in brickwork and blockwork
• General renovation and construction drilling where a 160 mm length is required

Key specifications

• Overall length: 160 mm
• Tip geometry: two-cutter head with individual carbide cutting tips
• Body material: hardened steel for increased strength
• Shank type: optimized mounting shank for improved grip and power transfer
• Primary materials for use: masonry, concrete, brick, stone, block

How to use

Insert the drill bit into a compatible chuck and tighten according to the drill manufacturer's guidance. For best results when drilling masonry, use a hammer drill mode and apply steady, moderate pressure; allow the bit to advance under its own cutting action rather than forcing it. Periodically withdraw the bit to clear dust and debris from the hole. For through-holes or deeper holes, drill in stages if necessary and ensure adequate cooling and cleaning between passes.

Usage recommendations

For prolonged bit life, match drill speed and feed to the substrate: use lower speeds with higher impact for dense concrete and moderate speeds for softer brick or block. Always use appropriate eye protection and dust extraction or respiratory protection when drilling masonry materials.
