Masonry drill bit Makita B-49127 10 pcs 5/6mm 6/8/10mm 10/12mm

The Makita B-49127 masonry drill bit set contains 10 carbide-tipped bits in a range of diameters and lengths designed for drilling in masonry materials. The set includes sizes 5/6 mm × 110 mm, two 6/8/10 mm × 160 mm, and 10/12 mm × 210 mm and is supplied in a compact hanging storage box for neat organization. These bits are intended for use with rotary hammers and other hammer-drill tools compatible with the included shank types, providing reliable penetration in concrete, brick and block work.

Advantages

The bits feature carbide tips engineered for impact drilling, improving wear resistance and maintaining cutting performance over repeated use. Multiple diameters and lengths in one set reduce the need to change tools between tasks, and the dedicated storage case protects the bits while keeping them accessible on a jobsite. The geometry of the tips and flute design aid efficient dust removal during drilling, which helps maintain drilling speed and reduces overheating.

Suitable for (tasks / use cases)

• Drilling holes in concrete for anchors and dowels
• Forming pilot holes in brick and masonry for fastener installation
• Creating passages through blockwork for wiring and conduit
• General construction and renovation tasks requiring hammer-drill masonry bits

How to use

Select the appropriate diameter and length for the required hole depth and anchor size. Secure the bit in your rotary hammer or hammer-drill according to the tool manufacturer’s instructions. When drilling masonry, use the hammer function and apply firm, steady pressure while allowing the tool and bit to do the work; avoid excessive lateral force. Periodically withdraw the bit to clear dust and debris from the hole to maintain drilling efficiency and reduce overheating. Replace worn bits when cutting performance or hole accuracy declines.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, dust mask, hearing protection and gloves) and follow safe working practices. Match bit diameter and length to anchor or fixture specifications, and ensure your rotary hammer is set to the correct mode for masonry drilling. Store bits in the provided hanging box to prevent damage and loss.
