Twist drill bit Bosch Expert SDS plus-7X

The Bosch Expert SDS plus-7X twist drill bit for rotary hammer drills is engineered for long-life drilling in reinforced concrete and other hard materials. With a 4-cutter Full Carbide Head and Bosch Carbide Technology, the bit resists jamming on rebar and maintains cutting performance under heavy use. Its robust tip-to-shank connection, produced with Bosch welding technology, improves durability for professional applications.

Advantages

The Full Carbide Head with a 4-cutter design reduces the risk of jamming and offers consistent cutting in cured and hardened concrete. Bosch Carbide Technology enhances tip hardness for extended life, while the reinforced tip connection increases resistance to impact and wear. Designed for SDS plus rotary hammer drills, the bit provides reliable performance and long service intervals for frequent drilling tasks.

Suitable for

• Drilling holes in cured concrete
• Drilling in hardened reinforced concrete and structures with rebar
• Working in hard natural stone such as granite and gneiss
• Professional construction tasks: fixings, installations and anchoring

How to use

Secure the SDS plus shank of the Bosch Expert SDS plus-7X into the rotary hammer according to the drill manufacturer’s instructions. Use the rotary hammer in hammer-drill mode for concrete and reinforced concrete. Apply steady axial pressure while allowing the tool to do the cutting; avoid excessive side load. When encountering rebar, maintain controlled feed to prevent sudden impacts. Withdraw the bit periodically to clear dust and debris and to cool the cutting head.

Usage recommendations

Use appropriate personal protective equipment (eye protection, hearing protection, gloves). Select the correct drill diameter and drilling speed for the application, and ensure the rotary hammer’s SDS plus chuck is compatible. For prolonged drilling in reinforced concrete, consider using drilling intervals to reduce heat buildup and prolong the carbide head life.
