## Summary description

DeWalt DT9440-QZ masonry drill bit designed for use with rotary hammers. Single-piece set with a drill diameter of 3.6 cm suitable for drilling into concrete, brick and masonry. Intended for heavy-duty rotary hammer applications where a large-diameter masonry bore is required. Useful for anchor installation, through-holes and service penetrations.

## Long description

DeWalt DT9440-QZ masonry drill bit is a single-piece SDS Max bit with a 3.6 cm diameter designed for rotary hammer use. Engineered for large-diameter holes in concrete, brick, stone and block work, this 570 mm-long drill bit supports heavy-duty drilling tasks such as anchor installation, through-holes and service penetrations. The tool combines a hardened steel body and a solid two-cutter head with individual cutting tips to maintain drilling speed and resist wear under demanding conditions.
Advantages
The optimised mounting shank ensures secure grip and efficient power transmission from the rotary hammer, reducing the risk of slipping. Hardened steel construction improves resistance to bending and breakage during high-torque applications. The solid two-cutter head, supported by two individual cutting tips, provides stable cutting action and fast material removal when drilling into masonry, concrete and stone. The long 570 mm length facilitates through-drilling and depth reach for anchor and service installations.
Suitable for
Drilling clearance and anchor holes in concrete and masonry
Creating through-holes for pipe and cable penetrations
Installing anchors and fixings in brick and block work
Fast removal of material in renovation and construction tasks
Key specifications

Overall length: 570 mm
Shank type: SDS Max
Body material: hardened steel
Tip configuration: solid two-cutter head with two individual cutting tips
Intended materials: concrete, brick, masonry, stone

How to use
Fit the DeWalt masonry drill bit into a compatible SDS Max rotary hammer according to the tool manufacturer’s instructions, ensuring the shank is fully engaged and locked. Select rotary hammer mode with rotation and impact enabled for masonry drilling. Start drilling at low speed to establish the hole, then increase pressure and speed to maintain efficient cutting while allowing the bit to remove debris. Withdraw periodically to clear dust and reduce heat buildup. For through-holes, mark required depth before drilling and use steady, controlled pressure throughout the operation.
Usage recommendations
Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. Match drill speed and feed pressure to the material: moderate steady pressure for concrete and masonry, avoiding excessive force that can overheat the bit. For prolonged jobs, allow the bit to cool and clear debris frequently to extend tool life. Ensure the rotary hammer and SDS Max chuck are in good condition to maintain secure mounting and optimal power transfer.
