Borr Cimco 20 8302

The Cimco 20 8302 drill bit is a PROFI SDS-Plus hammer drill made in Germany, designed for rotary hammers with SDS‑Plus holders. It has a 5 mm diameter and a total length of 110 mm. The bit features hard metal cutting edges and a Twinmax wide helix for high drilling speed while offering vibration‑optimised drilling behaviour certified by the German Masonry Drill Bit Testing Association (PGM) according to DIBt requirements.

Advantages

The hardened metal tip provides wear resistance and long service life, while the Twinmax helix design increases chip removal and drilling speed. Vibration‑optimised geometry reduces user fatigue and improves control during hammer drilling. The bit is certified by PGM and produced under German manufacturing standards, ensuring consistent quality and compatibility with all SDS‑Plus machines.

How to use

Insert the Cimco 20 8302 SDS‑Plus shank into a compatible rotary hammer with an SDS‑Plus holder and secure it according to the tool manufacturer's instructions. Select the hammer drilling mode for concrete or masonry, apply steady pressure, and let the drill perform the work—avoid excessive force. Retract periodically to remove dust and prevent clogging; use appropriate drill speeds and percussion settings recommended for a 5 mm masonry bit.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) when hammer drilling. For best results in reinforced concrete or very hard materials, use a new or sharpened carbide tip and check that the rotary hammer is set to the correct power and percussion settings for a 5 mm SDS‑Plus bit.
