How to use

Insert the SDS‑Plus shank into a compatible rotary hammer according to the tool manufacturer’s instructions. Secure the drill bit in the chuck, select the appropriate drilling mode for concrete or masonry, and apply steady pressure while allowing the tool to do the work. Withdraw occasionally to clear dust and chips for efficient drilling and to reduce heat buildup.

Usage recommendations

Use personal protective equipment (eye and ear protection, dust mask) and ensure the rotary hammer is suitable for SDS‑Plus bits. For extended or deep drilling, periodically remove the bit to clear debris and inspect for wear to maintain drilling performance.
