## Long description

DeWalt DT9401-QZ is a single 12 mm diameter drill bit designed for use with rotary hammers. With a solid 540 mm working length, this SDS Max shank bit provides extended reach for drilling deep holes in concrete and masonry. The tool is intended for professional and DIY tasks where hammer action and durable construction are required, offering a balance of penetration and stability for reinforced concrete, natural and artificial stone.
Advantages
The drill bit features a solid two-cutter head with two individual cutting tips to maintain drilling speed and efficiency. A four-flute helix and maximised flute entry enable faster debris evacuation while the reinforced core improves impact resistance and reduces the risk of breakage. Constructed from stainless steel, the bit is designed to withstand repeated hammering and abrasive conditions commonly encountered in masonry drilling.
Suitable for
Drilling deep anchor or through holes in reinforced concrete
Creating routes for plumbing or electrical conduits in masonry walls
Installing fixings in natural and artificial stone
General heavy-duty masonry drilling with a rotary hammer

How to use
Fit the SDS Max shank securely into a compatible rotary hammer according to the tool manufacturer's instructions. Mark the drilling position, use appropriate personal protective equipment, and start drilling at low speed to establish the hole before applying full hammer action. Withdraw the bit periodically to clear debris and prevent overheating; maintain steady axial pressure without forcing the bit to preserve cutting tip integrity. For deep holes, remove accumulated dust with compressed air or a brush during pauses.
Usage recommendations
Use the DeWalt DT9401-QZ with a rotary hammer rated for SDS Max bits and appropriate power for masonry work. Match drill diameter and length to the anchor or fixing specifications, and replace the bit when wear reduces cutting performance. For extended tool life, avoid lateral forces and ensure regular clearing of debris while drilling.
