Circle cutter drill bit, Wolfcraft 5459000 — 1 piece, for rotary hammer, right-hand rotation

Wolfcraft 5459000 is a single-piece circle cutter drill bit designed for rotary hammer use with right-hand rotation. The annular bit is fitted with heat-resistant tungsten carbide cutting plates soldered to a durable body and includes a mandrel with a specially hardened 110 mm SDS‑Plus shank. With a maximum cutting depth of 46 mm and a pre-assembled centring drill (Ø 8 mm, length 70 mm), this tool is prepared for immediate use in demanding masonry applications such as concrete, brick and hard stone.

Advantages

The tungsten carbide tipped plates and hardened SDS‑Plus shank deliver long service life and high wear resistance under hammering action. The pre-assembled design with a centring drill simplifies accurate positioning and reduces setup time. A user-friendly pin removal system allows the annular bit to be detached and changed without additional tools. TÜV testing confirms consistent manufacturing quality and safety for use with compatible rotary hammers.

Suitable for

• Drilling circular holes in concrete slabs and reinforced concrete (up to the specified depth).
• Creating openings in brick walls and masonry for installations and pipework.
• Cutting holes in kerbstones and other hard natural stone elements.
• Construction, extension and renovation projects requiring precise circular holes.

How to use

Fit the SDS‑Plus shank into a compatible rotary hammer chuck and ensure the tool is set for right-hand rotation and hammering mode if required by the material. Mark the hole centre, then use the pre-assembled centring drill (Ø 8 mm) to stabilise the bit and start the cut at low speed to establish the pilot position. Apply steady pressure without forcing the tool; allow the carbide cutting plates and hammer action to remove material. When the required depth is reached, withdraw the bit while running the tool briefly to clear debris, then use the pin release to remove the annular cutter from the mandrel if necessary.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling masonry. Select a rotary hammer with compatible SDS‑Plus interface and sufficient power for the chosen diameter and material. For extended cutting life, avoid excessive lateral force and allow the bit to cool periodically when performing multiple holes in hard stone or reinforced concrete.
