Bosch Masonry Drill Bit Set Hard Metal 4–10 mm, 5 pieces

The Bosch Masonry Drill Bit Set HM 4–10 mm is a 5-piece carbide (HM) masonry drill bit set. It is made for drilling into solid structural materials such as concrete, brick, blockwork, and stone. Operators use this assortment for standard masonry drilling without damaging the surrounding material. The bits cope with the heavy abrasion that comes with dense building materials. This practical accessory set is useful for anyone carrying out physical modifications to hard walls, floors, or external brickwork.

Rather than buying each diameter separately, this set offers a ready-to-use solution for a range of site requirements. It is intended for occasional home maintenance, domestic DIY, and small-scale construction work. The bits must be used with a suitable power drill or hammer drill to achieve the intended results. Applying the correct drilling technique ensures accurate hole sizes and extends the life of the equipment. Steady penetration rates are maintained when the bits are properly matched to the material being drilled.

• 4 mm, 5 mm, 6 mm, 8 mm, and 10 mm sizes provide an exact match for standard wall plugs and structural anchors.
• RS shank design ensures a reliable grip and rotational stability in compatible drill chucks.
• Total weight of 120 g keeps bulk to a minimum in tool bags or on tool belts.
• Smaller included diameters handle standard mounting work and tight fixture fittings.
• Larger bit options provide the clearance needed for heavy-duty wall anchors and full through-holes.
