The tool has a cutting diameter of 82 mm and is supplied as a single-piece hollow core drill for use with compatible SDS Plus rotary hammer drills.

Advantages

The drill features tungsten carbide tips and heat-resistant brazed plates for increased wear resistance and long life when cutting hard materials. The SDS Plus shank ensures secure, vibration-resistant mounting in rotary hammer drills, while the 8 mm centring drill improves accuracy and prevents wandering during start-up. Impact-resistant construction and special hardening provide reliable performance in masonry and concrete.

How to use

Fit the hollow core drill into a compatible SDS Plus rotary hammer drill and ensure the centring drill is correctly seated. Mark the drilling position and start drilling at low speed to engage the centring drill, then apply steady pressure and increase to the recommended operating speed for your tool. Withdraw periodically to clear debris and avoid overheating; keep the drill perpendicular to the work surface for a clean hole. Use appropriate personal protective equipment and follow the rotary hammer manufacturer's guidance.

Usage recommendations

Use this KWB SDS Plus hollow core drill with a rotary hammer that supports SDS Plus shanks and adjustable impact settings. For best results in reinforced concrete or very hard stone, use cooling pauses and remove debris frequently. Replace the drill if carbide tips show significant wear or damage to maintain hole quality and safety.
