Drill bit DeWalt DT60812-QZ, SDS‑plus, 540 mm, for concrete, 1 pc

DeWalt DT60812-QZ is a 540 mm SDS‑plus drill bit engineered for drilling in concrete, masonry and natural or artificial stone. Supplied as a single piece, this long rotary‑hammer bit is intended for use with SDS‑plus chucks and is suitable for through‑holes, anchoring and reinforcement work where extended reach and consistent performance are required. The bit features a solid carbide tip with four cutting faces and a long helix designed to maintain drilling speed and improve debris evacuation.

Advantages

The solid carbide tip with four cutting faces reduces the risk of jamming when encountering rebar and produces cleaner, more concentric holes while maintaining a steady drilling speed. The long helix profile and optimized free space accelerate removal of debris, reducing clogging and heat build‑up. An optimized heat treatment increases overall bit strength and durability, extending service life under heavy‑duty use.

Suitable for

• Drilling holes in reinforced concrete for anchors and through‑fixings
• Masonry drilling in brick, block and similar substrates
• Work in natural and engineered stone requiring a long‑reach bit
• Rotary hammer applications with SDS‑plus chucks

Key specifications

• Shank type: SDS‑plus
• Overall length: 540 mm
• Tip: solid carbide with four cutting faces
• Helix: long helix design with optimized free space for debris removal
• Material treatment: optimized heat treatment for increased strength
• Package quantity: 1 piece

How to use

Install the DeWalt SDS‑plus bit into the rotary hammer's SDS‑plus chuck according to the drill manufacturer's instructions. Use the hammer mode appropriate for concrete and masonry; start drilling at low speed to locate the position, then apply steady pressure and allow the tool to do the work. Periodically withdraw the bit to clear debris and reduce heat, especially when drilling deep holes. When encountering reinforcement, proceed with controlled feed to let the carbide tip cut through and avoid excessive lateral force.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and secure workpieces. Match drill speed and hammer settings to material hardness and hole depth. For best performance, periodically remove the bit to clear dust and allow cooling; replace worn bits to maintain hole quality and safe operation.
