SDS Max Masonry Drill Bit 25mm x 520mm

Description

SDS Max Masonry Drill Bit 25mm x 520mm is a heavy-duty hammer-drill bit for drilling deep, 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, even over its 520mm reach. 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 25mm diameter and 520mm long, contractors and tradies handling heavy fixing and anchor work reach for this size wherever large, deep fixing holes are needed in artificial stone, masonry, natural stone or reinforced concrete.
