Drill bit FISCHER Quattric II 8 x 165 mm for rotary hammer, 1 pc

FISCHER Quattric II 8 x 165 mm is a hammer drill bit with an SDS‑Plus adapter designed for use with rotary hammers. The 8 mm diameter and 165 mm overall length make it suitable for standard rotary‑hammer drilling tasks in construction and renovation. The bit features a carbide head and a two‑piece spiral design to increase drilling speed and service life, and its reinforcement chamfers reduce the risk of jamming when drilling near rebar. It is suitable for creating drill holes in accordance with PGM approvals where required.

Advantages

The carbide head and the new two‑piece spiral geometry provide faster progress and improved durability compared with conventional bits. Reinforcement chamfers prevent the bit from jamming against rebar and ensure more reliable drilling in reinforced concrete. The SDS‑Plus adapter allows quick, secure mounting in compatible rotary hammers.

Suitable for

• Drilling holes for anchors and fasteners in concrete, masonry and reinforced concrete
• Construction and renovation tasks requiring rotary‑hammer drilling
• Drilling where PGM‑compliant approval for hole quality is required

How to use

Insert the SDS‑Plus shank into a compatible rotary hammer and secure according to the tool manufacturer’s instructions. Start drilling at low speed to position the bit, then apply steady rotary‑hammer action with moderate axial pressure. Withdraw the bit periodically to clear dust and debris from the hole. When drilling near reinforcement, proceed slowly and let the reinforcement chamfers guide the bit to reduce the risk of jamming.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and follow the rotary hammer manufacturer's safety and maintenance instructions. Replace the bit when wear reduces drilling performance.
