Drill Bit Makita SDS‑MAX 25 x 200 x 340 mm 6‑cut (B-05290)

SDS‑MAX rotary drill bit by Makita with a 25 mm diameter, 200 mm working length and 340 mm overall length. The bit features a 6‑cut tip geometry designed for hammer drilling in concrete and masonry with compatible SDS‑MAX rotary hammers. Its defined cutting edges and flute design promote efficient removal of debris and stable drilling performance in heavy‑duty construction and installation tasks.

Advantages

The 6‑cut tip provides precise cutting edges that reduce wandering at the start of the hole and maintain consistent progression through hard materials. The long working length allows deeper drilling without tool extensions, while the overall length gives improved reach in confined or recessed work areas. The SDS‑MAX shank enables secure tool engagement and fast bit changes on compatible rotary hammers. The flute and tip geometry help evacuate dust and rubble, supporting steady drilling speed and reduced clogging.

Suitable for

• Hammer drilling holes in reinforced and non‑reinforced concrete
• Drilling openings for anchors, dowels and through‑fixings
• Installing electrical conduit and plumbing in masonry walls
• Construction and renovation tasks requiring deep or recessed holes

How to use

Install the bit into an SDS‑MAX compatible rotary hammer until it locks in place. Select the hammer drilling mode on the tool and position the bit perpendicular to the work surface. Apply steady pressure and allow the tool's hammering action to advance the bit; avoid excessive force which can accelerate wear. Periodically withdraw the bit to clear dust from the hole and check progress. For reinforced concrete, slow the feed when encountering rebar and use appropriate drilling techniques or bits for metal if persistent.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection and a dust mask. For prolonged or heavy drilling, ensure the rotary hammer is within the manufacturer’s recommended power range for SDS‑MAX bits and allow the bit to cool between extended runs. Replace the bit when cutting edges show visible wear or reduced drilling speed to maintain safe and efficient operation.
