Rotary drill bit Bosch SDS-plus-7X 20 mm diameter, 1000 mm length

Bosch SDS-plus-7X 20 mm diameter, 1000 mm length rotary drill bit is a long-format masonry bit engineered for use with SDS-plus rotary hammers. It is built to drill deep, accurate holes in concrete, reinforced concrete and masonry where extended reach is required. The bit's 20 mm cutting diameter and 1000 mm overall length provide the length and strength necessary for installations such as anchors, through-drilling and plumbing or electrical conduit runs that cannot be completed with standard-length bits.

Advantages

The SDS-plus-7X geometry offers improved hit rate and fast material removal while maintaining control during deep drilling. Hardened steel construction and a wear-resistant head design ensure consistent performance in abrasive concrete and masonry. The SDS-plus shank guarantees secure tool-to-bit connection, reducing wobble and enabling efficient power transfer from rotary hammers. Long length reduces the need for extensions or staged drilling, saving time on deep-hole tasks.

Suitable for

• Drilling deep anchor holes in concrete and reinforced concrete
• Through-drilling for pipes and electrical conduits
• Installation work requiring extended reach such as plumbing and HVAC
• Construction and renovation tasks in masonry structures

Key specifications

• Drill type: SDS-plus rotary hammer bit for percussion drilling
• Cutting diameter: 20 mm
• Overall length: 1000 mm
• Intended material: concrete, reinforced concrete, masonry
• Shank type: SDS-plus compatible

How to use

Install the bit into an SDS-plus rotary hammer according to the tool manufacturer's instructions until it locks securely. Select an appropriate drilling speed and percussion setting for concrete or masonry. Start drilling with firm, steady pressure and allow the tool to do the work; avoid excessive side loads that can bend long bits. Withdraw the bit periodically to clear dust and debris from the hole and to prevent clogging. For through-drilling, ensure access on the exit side or use controlled feed to maintain straightness over the full length.

Usage recommendations

Use appropriate personal protective equipment including eye and hearing protection and dust control measures. For reinforced concrete, use intermittent drilling and dust extraction to prolong bit life. Match the SDS-plus-7X 20 mm diameter to the anchor or pipe size required, and inspect the bit for wear or damage before each use.
