Borr Cimco 20 8304

Drill Bit Cimco 20 8304 is a PROFI SDS‑Plus hammer drill bit designed for rotary hammers with an SDS‑plus shank. With a diameter of 5 mm and overall length of 160 mm, this single‑piece bit features hard‑metal cutting edges and a wide Twinmax helix that produces high drilling speed while maintaining stable drilling behaviour. The bit is vibration‑optimised and certified by the German Masonry Drill Bit Testing Association (PGM) in accordance with the requirements of the German Institute for Building Technology (DIBt). Made in Germany and suitable for all machines with SDS‑plus holders.

Advantages

The Cimco 20 8304 combines hard metal blades and a Twinmax helix to deliver fast, precise drilling in masonry and concrete. Its vibration‑optimised design reduces user fatigue and improves drilling stability. Single‑piece construction increases durability and reliability, and the PGM/DIBt certification confirms compliance with recognized testing standards.

How to use

Insert the SDS‑plus shank of the Cimco 20 8304 into the rotary hammer according to the tool manufacturer’s instructions and ensure it is securely locked. Select the hammer‑drilling mode for concrete or masonry and apply steady pressure while keeping the drill perpendicular to the work surface. Clear dust from the hole periodically to maintain drilling efficiency. After use, remove the bit and store it in a dry place.

Recommendations

For optimal results, use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and select an SDS‑plus rotary hammer with power suitable for small‑diameter masonry drilling. Replace the bit when wear reduces cutting performance; inspect the hard‑metal tip regularly for chipping.
