Drill Bit Smart SDS-plus Duo 10 x 310/250 mm

The Drill Bit Smart SDS-plus Duo 10 x 310/250 mm is a rotary and hammer drill accessory designed for use with SDS-plus chucks. It features a 10 mm cutting diameter, a total length of 310 mm and a working length of 250 mm, making it suitable for drilling through concrete, masonry and natural stone. The bit's SDS-plus shank ensures secure retention in compatible drills and efficient transfer of percussive energy for reliable hole-making in construction and installation tasks.

Advantages

This SDS-plus drill bit combines a compact 10 mm diameter with an extended reach provided by its 310 mm overall length and 250 mm effective working length. The geometry of the cutting tip and flute design is tailored for percussion drilling into hard mineral substrates, enabling effective removal of chips and steady progress when drilling. The SDS-plus shank offers quick and secure insertion and removal in drills with compatible chucks, maintaining stable alignment during high-impact operation.

Suitable for

• Drilling anchor, dowel and through holes in concrete and reinforced concrete
• Making holes for electrical and plumbing installations in masonry walls
• Repair and renovation tasks requiring percussion drilling into stone
• Construction site work where SDS-plus rotary-hammer drills are used

Key specifications

• Cutting diameter: 10 mm
• Overall length: 310 mm
• Working (effective) length: 250 mm
• Shank type: SDS-plus
• Compatible materials: concrete, masonry, natural stone

How to use

Insert the SDS-plus shank into the compatible drill chuck until it locks. Select the hammer or rotary-hammer mode on the drill if percussion drilling is required. Position the drill perpendicular to the work surface and start at low speed to establish the pilot position, then apply steady pressure while allowing the drill's percussion action to do the cutting. Withdraw the bit periodically to clear accumulated dust and debris from the hole, especially when drilling deep holes close to the 250 mm working length.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For reinforced concrete or heavily reinforced sections, use controlled drilling pressure and consider a pilot or smaller diameter bit if rebar is encountered. Store the drill bit dry and protect the cutting tip from impacts to preserve drilling performance.
