The Gold Laser Spiral® core bit has been a Maxima exclusive since 2002, developed specifically for dry coring reinforced concrete. Since then it has been developed and restyled, and is absolutely the fastest and best performing tool on the market, and the best selling tool on both the national and international markets. Its unique characteristics include: the spiral on the steel body; its conical shape; the turbo segment with alternating concave/convex design: the reduced friction and upper discharge significantly larger than competitor tools, thus exceptionally improving the drilling speed. Useful core bit length: 150 mm.
