SDS Max Masonry Drill Bit 28mm x 370mm

Description

SDS Max Masonry Drill Bit 28mm x 370mm is a heavy-duty hammer-drill bit for drilling large-diameter plug and fixing holes in concrete, masonry and stone. Reinforced concrete, natural stone and dense masonry blunt an ordinary bit fast, and forward motion that drifts off-centre in armed concrete risks a hole that isn’t cylindrical or a bit that locks in the reinforcement steel. This bit uses the SDS-max W2 TURBOHEAD Xpro design: a W2 helix with asymmetrical shovel-shaped entry grooves and large-volume double hauling flutes clears drilling dust fast, while the depth-offset full carbide head and X-cutting, 2×2 cutting concept stop the bit locking in reinforcement and keep the hole exactly cylindrical even in armed concrete. Chrome-nickel-molybdenum steel construction is shot-peened and hardened to an intermediate level, with the carbide head high-temperature brazed at about 1,120°C for a bond that holds under heavy impact. It fits directly into SDS-max and HILTI TE-Y drive hammer drills and is made in Germany. At 28mm diameter and 370mm long, contractors and tradies handling heavy fixing and anchor work reach for this large-diameter size wherever bigger plugs, anchors or fixings need to go into artificial stone, masonry, natural stone or reinforced concrete.
