Maximum-Precision Deep Holes - The Long HSS Twist Drill Bit Ground is for drilling deep holes through metal with maximum precision. Its extended length makes this long bit capable of drilling deeply. more→The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling deep holes in alloyed and non-alloyed …

Very Robust for Formwork - The Installation Drill Bit is very robust for formwork. Its drill bit and shank end are screw-connected, which ensures a low risk of breakage and improves smooth-running ope more→rations. Furthermore, its tapered flute, offset drill bit and shank ends prevent jamming even in moist wood, while maintaining enough power to cut through embedded nails. Equipped with an extra-long shank, the bit delivers versatile drilling in multilayer building materials or sandwich materials, e.g. for building trade (formwork) and for interior fitting work, plumbing, heating and electrical installation. It is suitable for use on formwork, boards, planks, beams, plasterboard, light building materials,…

The Irwin SDS Speedhammer Plus Drill Bits are designed for SDS drilling. They drill exceptionally fast into brick, block, masonry, concrete and granite. The patented, unique single flute design ensure more→s efficient, speedy removal of dust and lower vibrations and 28% greater capacity meaning more efficient waste removal. They have a patented extra short drill bit head which means the head takes 80% of the workload, ensuring higher durability and speed. Clears drilling dust directly into the flute, reducing the risk of clogging. The bits have 25% more tungsten carbide for extra strength and they drill 25% faster than competitive drill bits with the same high durability. In addition, they have more …
