Hammer drill bit Bosch SDS Plus-5, 20 mm diameter, single piece

Bosch SDS Plus-5 hammer drill bit, 20 mm diameter, single piece, is designed for impact drilling in masonry and concrete using an SDS Plus chuck. The bit features an ActiveTec centring tip for precise starts, AWB brazing and hardening technology to reduce vibration and extend service life, and a visible wear mark that indicates when hole diameter tolerance for metal anchors is no longer met. The bit is PGM-certified and manufactured in Germany, and is intended as a single replacement or spare for drilling anchors, through-holes and utility mounting tasks with compatible SDS Plus rotary hammers.

Advantages

The ActiveTec centring tip guides the drill for stable and accurate starts, minimizing wandering and chipping. AWB brazing and hardening improves tip strength and reduces vibration transmitted to the user, helping to maintain drilling performance under load. A wear mark provides a clear visual indicator of remaining usable diameter for reliable anchor seating. PGM certification ensures conformity to tight tolerances and consistent drilling behaviour.

Suitable for

• Impact drilling in concrete and masonry
• Drilling holes for metal anchors and fixings
• Creating through-holes for pipes and conduits
• Replacement or spare bit for SDS Plus rotary hammers

How to use

Fit the 20 mm SDS Plus-5 bit into an SDS Plus rotary hammer according to the tool manufacturer's instructions and ensure the bit is securely locked in the chuck. Mark the drilling position and start at low speed to engage the ActiveTec centring tip, then apply steady pressure and the appropriate hammer function for masonry or concrete. Withdraw the bit periodically to clear dust and reduce heat build-up. Monitor the wear mark to confirm the hole diameter remains within the tolerance required for the intended anchor or fixing.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves and hearing protection. Match drill depth to anchor specifications and allow the bit to cool between long runs. Replace the bit when the wear mark indicates the diameter is no longer within tolerance to ensure reliable anchor performance.
