SDS+ Concrete Drill Bit Expert+ 14 x 250 x 300 mm, 20 pcs

SDS+ Concrete Drill Bit Expert+ 14 x 250 x 300 mm, 20 pcs is a set of 20 carbide-tipped masonry bits designed for use with SDS+ rotary hammers. Each drill bit has a 14 mm diameter, 250 mm working length and 300 mm total length, intended for drilling clean, accurate holes in concrete, brick and other common masonry materials. The pack is suited to jobs that require multiple identical holes and allows quick replacement on compatible SDS+ chucks.

Advantages

The Expert+ SDS+ drill bits feature a tungsten carbide tip for improved wear resistance and maintained cutting performance during repeated use. Their standardized shank ensures fast, secure engagement in SDS+ rotary hammers and reduces bit wobble for straighter holes. The combination of working and total length provides extended reach while maintaining efficient debris evacuation for consistent drilling speed.

Suitable for

• Drilling anchor and dowel holes in reinforced and non-reinforced concrete
• Installing electrical conduit boxes and plumbing fixtures in masonry walls
• Repetitive hole-making on construction sites and renovation projects
• Professional and DIY tasks requiring stable, repeatable 14 mm boreholes

How to use

Fit the appropriate-sized SDS+ bit into the rotary hammer chuck according to the tool manufacturer’s instructions. Mark the drilling position, start at low speed to create a guide point, then apply steady pressure and operate the hammer function for concrete or masonry. Periodically withdraw the bit to clear dust and debris and to prevent overheating; adjust drilling speed and pressure according to material hardness. Replace bits from the pack as wear reduces cutting efficiency.

Usage recommendations

Use with a rotary hammer that supports SDS+ shanks and select the hammer mode for concrete. Wear appropriate personal protective equipment—safety goggles, hearing protection and a dust mask or extraction—to manage chips and silica dust. For longer service life, avoid excessive side loads and remove debris regularly while drilling.
