Bosch Professional SDS Plus-5X Hammer Drill Bit - 5.5mm x 400mm x 460mm

This drill bit is specifically designed for drilling into masonry, concrete, and reinforced concrete.

You need a rotary hammer with an SDS plus chuck to use this drill bit. It is not compatible with standard drill chucks.

The 4-cutter head is designed to prevent jamming and breakage, especially when drilling into reinforced concrete, ensuring more efficient and reliable drilling.

It features large, short dust removal channels and a 'turn-angle' head that efficiently extract dust, reducing heat build-up and allowing for faster drilling.

The PGM Masonry Drill Bit Association Board test mark indicates that the bit meets strict quality standards for drilling accuracy, tight tolerances, and the reliable hold of fixings.

The SDS plus-5X drill bit lasts up to 1.5x longer than a standard Bosch SDS plus-1 Drill Bit.

No, this bit is specifically engineered for hard masonry materials and is not suitable for drilling wood or metal.

Ensure the rotary hammer is set to the correct mode (hammer drill mode). Verify the bit is fully seated in the SDS plus chuck.

Check if the bit is dull or damaged. Ensure dust removal channels are clear. Verify the rotary hammer has sufficient power and is operating correctly.

This is less common with the 4-cutter head. Ensure you are using appropriate pressure and not forcing the bit. If encountering dense rebar, proceed with caution and ensure adequate dust removal.

Ensure the centring tip is properly engaged with the surface. Mark your drilling point clearly. For very hard surfaces, consider a small pilot divot.
