How to use

Select the appropriate drill bit size for the required hole diameter, insert the SDS‑Plus shank into the rotary hammer according to the tool manufacturer’s instructions and secure it. Position the centring tip on the marked spot, apply steady pressure and start drilling at low speed to establish the hole, then continue with the recommended hammering/drilling setting. Withdraw the bit occasionally to clear debris and avoid overheating. Observe the wear mark to determine when the bit has reached its service limit in accordance with PGM.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection) and a suitable rotary hammer rated for SDS‑Plus bits. For reinforced concrete, start with a smaller diameter pilot hole if required and avoid excessive side pressure on the bit to reduce risk of breakage. Store the bits in the supplied plastic box to protect the carbide tips.
