Rotary SDS-plus drill bit DeWalt DT8930 10 x 260/200 mm

DeWalt DT8930 is an SDS-plus rotary drill bit with a 10 mm diameter and total length of 260 mm, featuring a 200 mm working length. Engineered for use with SDS-plus rotary hammers, this drill bit is intended for drilling accurate holes in concrete, masonry and natural stone. The carbide tip and optimized flute geometry deliver consistent drilling progress and stable hole sizing for construction and renovation applications.

Advantages

The SDS-plus shank enables secure, vibration-resistant bit retention in compatible rotary hammers for efficient impact drilling. A precision-ground carbide tip improves wear resistance and cutting performance in abrasive materials, while the long 200 mm working length provides extended reach without sacrificing stability. The flute design evacuates dust and debris effectively to maintain chip removal and reduce bit binding during prolonged use.

Suitable for

• Drilling anchor and fixing holes in concrete and reinforced concrete
• Creating service holes in masonry and brickwork
• Installing through-fittings and dowels in stone and block materials

Key specifications

• Shank type: SDS-plus
• Diameter: 10 mm
• Total length: 260 mm
• Working length: 200 mm
• Tip material: carbide
• Applicable materials: concrete, masonry, natural stone

How to use

Fit the SDS-plus shank into a compatible rotary hammer according to the tool manufacturer's instructions and ensure it is locked in place. Mark the drilling point, start drilling at low speed to centre the bit, then apply steady pressure while using the hammer function for impact drilling in concrete or masonry. Withdraw the bit occasionally to clear dust and maintain cooling; for deeper holes, periodically retract the bit to improve debris evacuation.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and dust mask. Match drill diameter to anchor or dowel specifications, and use correct hammer settings for the substrate to avoid overloading the tool or bit. For reinforced concrete, take care to avoid prolonged contact with rebar and consider using a rebar-detecting device before drilling.
