Drill bit DeWalt DT9531 SDS-Plus 8 x 260/200 mm

SDS-Plus drill bit DeWalt DT9531 8 x 260/200 mm is a rotary-hammer accessory intended for drilling through concrete, brick and other mineral-based building materials. The bit has an 8 mm working diameter and a total length of 260 mm with a 200 mm effective drilling length, a cylindrical SDS-Plus shank and a reinforced tip designed to improve chip removal and sustain impact loads. It is compatible with SDS-Plus chucks and is suitable for both professional tradespeople and home users performing drilling and fixing tasks in masonry.

Advantages

The reinforced carbide tip and flute geometry provide faster drilling progress and more efficient removal of dust and debris from the hole. The SDS-Plus cylindrical shank ensures secure retention in compatible rotary hammers and quick bit changes. The overall length combined with the working length allows deeper anchor and through-hole drilling while maintaining good rigidity for an 8 mm diameter bit.

Suitable for

• Drilling holes in reinforced and non-reinforced concrete
• Installing anchors, wall plugs and fasteners in masonry
• Through-holes for pipes, conduits and cable entries (small diameter)
• General renovation and construction work involving mineral substrates

Key specifications

• Drilling diameter: 8 mm
• Overall length: 260 mm
• Working/drill length: 200 mm
• Shank type: SDS-Plus cylindrical shank for rotary hammers
• Tip: reinforced carbide tip with optimized flute geometry for chip evacuation
• Material application: concrete, masonry and other mineral materials

How to use

Insert the SDS-Plus shank firmly into the rotary hammer chuck and ensure the bit locks into place before operation. Use the hammer mode of the tool when drilling into concrete and masonry; apply steady axial pressure without forcing the bit to avoid premature wear. For deeper holes, periodically withdraw the bit to clear dust and improve cooling. Wear appropriate personal protective equipment such as safety glasses, hearing protection and a dust mask when drilling mineral materials.

Usage recommendations

Use the drill bit with a rotary hammer that supports SDS-Plus shanks, select appropriate hammer speed and impact settings for an 8 mm bit, and avoid excessive lateral force. For reinforced concrete, use a slower feed rate and retract occasionally to remove debris. Store the bit in a dry place and inspect the tip for wear before reuse; replace the bit when the tip is visibly blunted or chipping reduces drilling efficiency.
