The Tru-Cut Manufacturing, Inc. PMQ125021 is a professional-grade hammer drill bit designed for high-performance drilling in concrete and reinforced concrete. It features the specialized Viper Head Quad Tip (4-cutter) geometry, which provides a cleaner, more symmetrical hole and reduces the risk of the bit jamming when encountering rebar.
This bit is engineered with rounded carbide 'fangs' or bullets that are designed to bounce off steel reinforcement rods, allowing the operator to maintain control and preventing catastrophic damage to the carbide tip. The ThunderTwist flute design works in tandem with a high-strength copper brazing alloy to ensure rapid dust evacuation and exceptional bonding. Each bit is vacuum heat-treated and shot-peened to provide maximum strength and longevity under extreme job site conditions.
