The Innovative EXTREME 2 SDS-Plus drill bit is suitable for fast drilling of plug, anchor, or clearance holes in masonry, stone, concrete and brick/block work. Superior carbide grade ensures a tip wit more→h outstanding durability which gives a constant drilling life. Optimised 4 flute spiral design allows efficient debris removal and incorporates a maximised central core for increased durability and energy transmission. Hardened Steel body for extra strength and reduced breakage. the 140 tip design ensures better bit penetration, longer life, faster drilling and greater durability.

It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers. The HSS Twist Drill Bit Ground is for drilling through metal with maxim more→um precision. 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 holes in alloyed and non-alloyed …
