Drill Bit Makita SDS‑MAX 28 x 200 x 340 mm, 6‑cut Maxi, B-05315

Makita SDS‑MAX 28 x 200 x 340 mm, 6‑cut Maxi, B-05315 is a carbide‑tipped SDS‑MAX drill bit designed for rotary hammers. With a 28 mm diameter, 200 mm working length and 340 mm overall length, this bit is made for drilling anchor holes, through‑holes and rebar‑free borework in concrete and masonry. The six‑cut Maxi tip improves material removal and drilling stability when used with compatible SDS‑MAX rotary hammers.

Advantages

The six‑cut Maxi tip geometry facilitates faster dust evacuation and balanced cutting forces for cleaner, more consistent holes. Its SDS‑MAX shank provides secure tool engagement and efficient impact transfer. The combination of working length and overall length gives access to deeper anchoring points while maintaining shaft rigidity. The bit is suitable for repeated use in construction and renovation where reliable concrete drilling is required.

Suitable for

• Drilling anchor holes in concrete and masonry
• Creating through‑holes for pipes and conduits (where no rebar is present)
• General light to medium construction demolition and renovation drilling tasks

Key specifications

• Diameter: 28 mm
• Working length: 200 mm
• Overall length: 340 mm
• Tip type: 6‑cut Maxi carbide tip
• Shank type: SDS‑MAX
• Intended materials: concrete, masonry (rebar‑free)

How to use

Install the bit into an SDS‑MAX rotary hammer following the tool manufacturer's instructions until it locks securely. Select the rotary hammer mode appropriate for drilling in concrete and start drilling at low RPM to position the hole, then apply steady pressure while allowing the tool's impact action to advance the bit. Withdraw the bit periodically to clear dust and prevent overheating. Avoid using the bit to drill into reinforced concrete containing rebar; for such work, use a dedicated rebar‑cutting system or bit rated for reinforcement.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask, hearing protection and gloves). For consistent results, ensure the rotary hammer is rated for SDS‑MAX accessories and matches the bit diameter and length for the intended anchoring depth. For prolonged bit life, maintain moderate feed pressure, clear dust from the hole regularly, and store the bit dry when not in use.
