Drill Bit Bosch SDS plus-7X 5.5mm 265mm

The Bosch SDS plus-7X 5.5mm 265mm drill bit is designed for use with SDS plus rotary hammers. With a 5.5 mm diameter and a 265 mm overall length, this single carbide-tipped hammer bit is intended for drilling in concrete, reinforced concrete and other hard masonry materials. The SDS plus shank enables fast bit changes and secure retention in compatible rotary hammer drills, while Bosch carbide and welding technologies are used at the tip to increase wear resistance and strength.

Advantages

The 4‑cutter full carbide head reduces the risk of jamming on rebar and improves impact resistance compared with standard two‑cutter designs. Reinforced tip welding and Bosch Carbide Technology extend service life, with manufacturer's claims of significantly longer life under demanding conditions. The SDS plus shank provides quick tool changes and stable connection to the drill, and the 265 mm length offers reach for through‑work and medium‑depth anchoring tasks.

Suitable for

• Drilling holes in cured concrete and hardened reinforced concrete
• Creating fixings and anchor points in masonry
• Drilling into hard natural stone such as granite and gneiss

Key specifications

• Shank type: SDS plus
• Tip type: Full carbide 4‑cutter head
• Diameter: 5.5 mm
• Overall length: 265 mm
• Suitable material: concrete, reinforced concrete, hard stone, masonry

How to use

Insert the SDS plus shank into the chuck of a compatible rotary hammer until it locks. Select the hammer drilling mode on the tool and align the bit with the marked drilling point. Apply steady forward pressure without forcing; allow the rotary hammer and the carbide head to do the cutting. Withdraw the bit occasionally to clear dust from the hole when drilling deep or through dense material. Replace the bit if excessive wear or damage to the carbide head is observed.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a mask when drilling. For best results in reinforced concrete, use progressive drilling: start with a pilot hole if necessary and use a correct drill speed and hammer setting for the material. Store the bit in a dry place to avoid corrosion at non‑carbide surfaces.
