## Summary description

DeWalt DT9543-QZ is a 310 mm drill bit supplied as a single piece for drilling applications. Designed for use with compatible drills, it provides the length needed for deeper holes and reach in construction, carpentry, and renovation tasks. Supplied individually, it is suitable for professionals and DIY users requiring a long-reach drilling solution.

## Long description

DeWalt DT9543-QZ is a single-piece 310 mm masonry drill bit designed to create deep, accurate holes in concrete, brick and stone. The extended length provides reach for anchor, plug and clearance drilling in construction, renovation and installation tasks. The bit features a solid two-cutter head with two individual cutting tips and a hardened steel body to deliver consistent drilling performance and improved resistance to breakage when used with compatible rotary or percussion drills.
Advantages
The optimized mounting shank ensures a secure grip and efficient power transfer from the drill to the bit, reducing slippage during use. The two-cutter head combined with twin cutting tips produces fast material removal and stable drilling, while the hardened steel body increases durability and lowers the risk of fracture under heavy loads. Supplied as a single piece, this 310 mm bit offers a straightforward long-reach solution for tasks that require deeper holes.
Suitable for
 Drilling anchor and plug holes in concrete and masonry
 Creating clearance holes for through-fixings in brick or blockwork
 Deeper drilling in renovation, carpentry fittings and HVAC or electrical installations
 Use with rotary or hammer drills where extended reach is needed
Key specifications
 Overall length: 310 mm
 Design: single-piece masonry drill bit with two-cutter head
 Tip configuration: two individual cutting tips for efficient drilling
 Shank: optimized mounting shank for secure grip and power transmission
 Material: hardened steel body for enhanced strength and reduced breakage
 Application materials: masonry, concrete, stone, brick and block
How to use
Install the drill bit into a compatible rotary or hammer drill, ensuring the shank is securely clamped in the chuck. Select the appropriate drill mode (rotary with hammer action for masonry) and start at low speed to position the bit, then increase to the recommended operating speed for your drill while applying steady axial pressure. Withdraw the bit periodically to clear dust from the hole and avoid overheating. For anchor or plug holes, check the required diameter and depth before drilling and verify hole cleanliness prior to inserting fixings.
Usage recommendations
Use protective eyewear and dust extraction where possible. Match drill speed and hammer action to the material; for harder concrete reduce speed and allow the bit to cool. Replace the bit when cutting performance declines or tip damage is visible to maintain hole quality and safe operation.
