Twist drill bit Bosch Expert SDS plus-7X

The Bosch Expert SDS plus-7X twist drill bit (model 2608900121, EAN 4059952531946) is a carbide-head SDS‑plus bit designed for rotary hammer drills. With a diameter of 1.4 cm and a single-piece Full Carbide Head, it is engineered to drill reinforced and very hard materials while delivering extended tool life and reliable performance for professional applications.

Advantages

The Full Carbide Head uses a 4‑cutter design manufactured from a single piece of carbide to reduce jamming in rebar and resist impact damage. A Bosch Carbide Technology tip and Bosch welding technology at the tip connection increase durability and ensure a highly resistant bond between the tip and the shank. The bit is optimized for use in SDS‑plus rotary hammer drills and provides longer service life compared with standard two‑cutter bits.

Suitable for

• Drilling holes in cured concrete
• Drilling hardened reinforced concrete
• Drilling hard natural stone such as granite and gneiss
• Fixings and installations for construction professionals using rotary hammer drills

How to use

Fit the Bosch Expert SDS plus‑7X bit into an SDS‑plus rotary hammer according to the tool manufacturer's instructions until it locks securely. Select the hammer drilling mode and a suitable rotational speed for the material. Apply steady axial pressure, let the tool do the cutting, and withdraw periodically to clear debris when drilling deeper holes. For rebar encounters, maintain control and avoid excessive lateral loading to reduce bit wear.

Usage recommendations

Use personal protective equipment (eye and ear protection, dust mask) and follow site safety rules. For best life and performance, use the bit with compatible SDS‑plus rotary hammers, select correct drill speed and feed, and replace the bit when tip wear visibly reduces drilling performance.
