4 Way Spearpoint Drill Bit

Achieve perfectly clean, chip-free holes in brittle surfaces with our professional-grade 4 Way Spearpoint Drill Bit. Specifically engineered for glass, ceramic, mirrors, and tiles, this bit features a cross-flute/4-facet diamond spear point design that shaves away material rather than violently cutting it, drastically reducing the risk of cracking or blowout.

Equipped with an ultra-durable tungsten carbide tip, this drill bit delivers superior heat resistance, accurate penetration, and exceptional tool longevity even during extended trade use.
