Borr Cimco 20 8308

The Cimco 20 8308 PROFI SDS-Plus hammer drill is a 6 mm diameter, 110 mm length, single-piece drill bit designed for use with rotary hammers that accept SDS-plus holders. Made in Germany, it features hard-metal cutting tips and a wide Twinmax helix for high drilling speed and consistent performance. The bit has vibration-optimised drilling behaviour and is certified by the German Masonry Drill Bit Testing Association (PGM) in accordance with DIBt requirements.

Advantages

The hard-metal blades maintain sharpness and durability when drilling into masonry and concrete, while the Twinmax helix increases drilling speed and efficient removal of debris. Vibration-optimised geometry reduces user fatigue and improves control during prolonged use. Certification by PGM (per DIBt requirements) confirms reliable quality and safety for professional applications.

How to use

Insert the drill bit into an SDS-plus rotary hammer until it locks in place. Select the hammer or rotary-hammer mode appropriate for the material. Start drilling with steady pressure, allowing the drill bit’s carbide tip and Twinmax helix to remove debris efficiently. Withdraw occasionally to clear dust from the hole and to avoid overheating. For precise small-diameter holes keep the drill perpendicular to the work surface and maintain controlled pressure.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and gloves). Match drill speed and hammer force to the material; increase cooling breaks when drilling dense concrete. Replace the bit when cutting performance or tip integrity deteriorates.
