Drill Bit SDS‑Max double twist drill Hikoki 754361

The Hikoki SDS‑Max double twist drill 754361 is a rotary hammer accessory engineered for use with SDS‑Max chucks. Its double twist flute geometry facilitates faster removal of dust and chips when drilling into concrete and masonry, supporting steady drilling progress and reduced clogging. The bit is designed for professional and construction environments where reliable performance and compatibility with SDS‑Max rotary hammers are required for creating anchor holes, clearing rebar paths and making openings for building installations.

Advantages

The double twist flute design improves chip evacuation and dust extraction compared with standard single‑flute bits, which helps maintain cutting efficiency and reduces the risk of bit binding in deep holes. The SDS‑Max shank provides secure coupling to compatible rotary hammers for effective hammering action and torque transfer. The drill geometry balances drilling speed and hole quality in concrete and masonry, offering consistent performance across repeated operations.

Suitable for

• Drilling anchor holes in concrete and reinforced concrete
• Creating passage for building installations such as conduits and pipes
• Clearing or enlarging holes around rebar locations
• Contractor and construction site drilling tasks requiring SDS‑Max tooling

Key specifications

• Shank type: SDS‑Max compatible shank for rotary hammers
• Flute design: double twist flutes for improved chip and dust removal
• Intended materials: concrete and masonry
• Application: percussion drilling with rotary hammers
• Typical use environment: professional construction and contracting work

How to use

Install the bit into the SDS‑Max chuck of a compatible rotary hammer following the tool manufacturer’s instructions until it locks securely. Select the hammer or hammer‑drill mode appropriate for concrete or masonry. Start drilling with light axial pressure to allow the bit to establish the hole, then apply steady, even pressure while allowing the hammer action to do the work. Withdraw the bit periodically from deeper holes to clear accumulated dust and chips and to avoid overheating or binding. Replace the bit when wear degrades drilling efficiency or hole quality.

Usage recommendations

Use personal protective equipment including safety glasses, hearing protection and dust mask when drilling concrete or masonry. For effective dust control, combine the double twist drill with a compatible extraction system or intermittent withdrawal technique. Match the drill diameter and length to the intended anchor, conduit or clearance requirement and ensure the rotary hammer is rated for SDS‑Max tooling and the intended drilling depth.
