Drill Bit KWB 261512 1.2 cm for Concrete Aerated Concrete

The KWB 261512 drill bit with a 1.2 cm diameter and SDS Plus shank is designed for use with rotary hammers to drill holes in aerated concrete, concrete, sandstone and stone. Packaged in a polybag with a hanging hole, it is convenient for storage and display. The bit features a CROSS-TIP 4-way cutting tip and a multi-phase spiral for efficient chip removal, enabling low-vibration, smooth running and high drilling efficiency.

Advantages

The CROSS-TIP 4-way cutting tip reduces snagging and improves centring on the drilling surface. High-temperature brazing increases tip durability under heavy load. The multi-phase spiral efficiently evacuates dust and debris, which supports steady drilling performance and reduces vibration during use. The SDS Plus shank ensures secure tool engagement and quick bit changes.

Suitable for

• Drilling wall plug and anchor fixing holes in concrete
• Drilling into aerated concrete (porous concrete blocks)
• Work on sandstone and natural stone
• Use with rotary hammers that accept SDS Plus shanks

How to use

Insert the drill bit into an SDS Plus compatible rotary hammer until it locks. Select the hammer or rotary mode as appropriate for the material (use hammer mode for concrete and stone). Start drilling at low speed to establish the hole, then apply steady pressure and maintain a consistent drilling speed. Periodically withdraw the bit to clear accumulated dust and allow the multi-phase spiral to evacuate debris effectively. Replace the bit if signs of excessive wear or damage appear.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, dust mask and hearing protection) and clean the work area of loose debris before drilling. For reinforced concrete or when drilling large-diameter holes, use the correct drill size and a suitable rotary hammer with sufficient power.
