Drill bit DeWalt DT60815 SDS‑Max XLR 19 x 550/670 mm

DeWalt SDS‑Max XLR 19 x 550/670 mm drill bit DT60815 is a purpose-built masonry bit for SDS‑Max rotary hammers. With a 19 mm cutting diameter and dual usable lengths (550 mm working length, 670 mm overall length), this bit is intended for drilling clean holes in concrete, reinforced concrete and other masonry materials. The XLR connection ensures a secure fit in compatible SDS‑Max chucks and aims to transfer impact energy efficiently for consistent drilling performance on construction and renovation sites.

Advantages

The XLR connection provides an improved coupling between the bit and the rotary hammer, reducing play and improving impact transfer for steady drilling in dense materials. The 19 mm diameter offers a balance between hole size and bit durability, suitable for anchor installation and through-holes. The length options give reach for deeper holes or overhead work while maintaining control and alignment. The geometry and carbide tip are designed to resist wear and preserve cutting performance in abrasive masonry.

Suitable for

• Drilling anchor and dowel holes in concrete and reinforced concrete
• Making passage holes for pipes and conduits in masonry
• Renovation and construction tasks requiring deep or long-reach drilling
• Professional trade use with SDS‑Max rotary hammers

Key specifications

• Shank type: SDS‑Max XLR connection for secure engagement
• Cutting diameter: 19 mm
• Working length: 550 mm; overall length: 670 mm
• Material: carbide‑tipped cutting head suitable for masonry and concrete
• Intended use: rotary hammer drilling for concrete, reinforced concrete and masonry

How to use

Install the DeWalt DT60815 into an SDS‑Max compatible rotary hammer according to the tool manufacturer’s instructions, ensuring the XLR connection locks in place. Select the hammer or rotary mode appropriate for concrete drilling and start at low speed to position the bit, then apply steady pressure and maintain alignment with the hole axis. Clear dust regularly from the hole to maintain drilling efficiency and prevent overheating. For reinforced concrete, use controlled feed rates and allow the tool and bit to do the work rather than excessive force.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask. Match the bit diameter and length to the anchor or sleeve size specified for the installation. Replace the bit when the carbide tip shows significant wear or produces reduced drilling speed to maintain hole quality and reduce stress on the rotary hammer.
