Bosch PRO M4 SDS Max Masonry Drill Bit

The Bosch PRO SDS max-4 Masonry Drill Bit is built for drilling reinforced concrete in infrastructure, commercial and domestic construction. Its hardy 4-cutter head is designed to keep going when you hit rebar, resisting jamming and breaking. Bosch states it lasts up to 1.5x longer than a Bosch SDS max-2 drill bit.

The head is made from high-quality tungsten carbide, so it can cut accurate holes in tough materials while keeping its strength and durability. Deep-channel fluting clears the dust and chips produced by large-diameter SDS max drilling, helping the bit keep performing for longer.

Available in a wide range of diameters, from 12mm to 40mm, and in lengths from 320mm to 940mm. Each bit is supplied as a pack of 1 and fits all SDS max rotary hammers. Select your size above to see the details for that variant.
