Drill bit DeWalt DT8910 SDS-plus 5.5×110/50 mm

DeWalt DT8910 SDS-plus 5.5×110/50 mm is a drill bit designed for percussive drilling in masonry and concrete with SDS-plus hammer drills. The 5.5 mm diameter and 50 mm working length provide a compact solution for installation and light construction tasks where through-holes or depth-limited holes are required. The SDS-plus shank enables quick, secure bit changes and reliable retention in compatible rotary hammer chucks.

Advantages

The solid carbide tip and optimized flute geometry ensure efficient dust removal and consistent drilling performance in brick, block and concrete. The SDS-plus shank guarantees fast tool-to-bit coupling and reduced slippage during hammering. With a total length of 110 mm and a 50 mm effective drilling depth, the bit balances reach and control for routine installation work. The bit construction is intended to deliver repeatable hole quality and stable drilling speed in standard masonry applications.

Suitable for

• Drilling anchor and fixings holes in brick and concrete
• Creating through-holes and depth-limited holes for installations
• Electrical and plumbing mounting tasks in masonry walls
• Light construction and retrofit work requiring SDS-plus hammer drills

Key specifications

• Drill diameter: 5.5 mm
• Total length: 110 mm
• Working (effective) length: 50 mm
• Shank type: SDS-plus
• Intended material: masonry, concrete, brick, block

How to use

Insert the SDS-plus shank into a compatible rotary hammer chuck until it locks. Set the tool to hammer drilling mode and select appropriate speed and impact settings according to the rotary hammer's manual and the substrate. Start drilling with steady pressure, avoiding excessive force; periodically withdraw the bit to clear debris for deeper holes. For depth-limited holes, use the working length as a guide or fit a mechanical depth stop on the drill.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling masonry. Match drill speed and hammer settings to the substrate and use a proper vacuum or dust extraction method where required. Replace the bit if tip wear or breakage occurs to maintain hole accuracy and safe operation.
