Drill bit set Makita B-49046 7 pcs SDS Plus for concrete

The Makita B-49046 drill bit set contains seven SDS Plus bits designed for drilling in concrete. The set covers a range of diameters and lengths — 5x110, 6x110, 6x160, 8x110, 8x160, 10x160 and 12x160 mm — to meet common on-site and renovation requirements. The SDS Plus shank provides secure retention in compatible rotary hammers, enabling efficient energy transfer for percussion drilling into masonry and reinforced concrete.

Advantages

The SDS Plus interface ensures quick bit changes and reliable clamping in rotary hammers. A selection of diameters and lengths in one set reduces downtime by matching drill size to the task without needing separate purchases. The bits are optimized for percussion drilling into concrete and masonry, offering consistent hole quality and predictable wear characteristics under normal use conditions.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Preparing holes for dowels and expansion bolts
• General construction and renovation tasks requiring varied hole sizes

How to use

Select the bit diameter appropriate for the hole and fixture. Insert the SDS Plus shank into a compatible rotary hammer until it locks. Use the hammer drilling mode with steady axial pressure, allowing the tool and bit to do the work; avoid excessive lateral force. Clear dust from the hole periodically to maintain drilling efficiency and inspect the bit for wear after repeated use.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust extraction where possible. Match bit length and diameter to anchor specifications and avoid applying side loads that can cause premature bit wear or tool damage. Store bits in a dry place to prevent corrosion.
