Drill Bit Cimco 20 8330

The Cimco 20 8330 is a PROFI SDS-Plus hammer drill bit designed for rotary hammers. With a 10 mm diameter and overall length of 160 mm, this single-piece drill bit is manufactured in Germany and suitable for all machines with SDS‑Plus holders. It features hard-metal cutting edges and a wide Twinmax helix for high drilling speed, while vibration-optimised drilling behaviour increases comfort and control. The bit is certified by the German Masonry Drill Bit Testing Association (PGM) in accordance with requirements set out by the German Institute for Building Technology (DIBt).

Advantages

Hard-metal blades provide wear resistance and a long service life; the Twinmax helix design improves dust removal and enables faster drilling. Vibration-optimised geometry reduces hand-arm vibration transmission during operation, enhancing drilling stability. Compatibility with all SDS‑Plus holders ensures easy mounting and broad usability across common rotary hammer models.

Suitable for

• Drilling into masonry, concrete and brick
• Professional construction and renovation work with SDS‑Plus rotary hammers
• DIY projects requiring reliable and durable hammer drill bits

How to use

Fit the drill bit securely into the SDS‑Plus chuck of a compatible rotary hammer. Select the hammer or rotary-hammer mode appropriate for the material, start drilling at low speed to position the bit, then apply steady pressure and allow the tool and bit to do the work. Periodically withdraw the bit to clear dust and prevent clogging, and avoid overheating by using controlled feed force and short pauses when drilling deep holes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, hearing protection). For best results in reinforced concrete or very hard masonry, use a suitable hammer setting and replace worn bits to maintain drilling performance. Store the bit dry to prevent corrosion.
