Fully Ground Craftsmanship: Unlike cheaper milled bits, our fully ground manufacturing process ensures ultra-precise dimensions, a sharper cutting edge, and a significantly smoother surface for flawless chip ejection.
Optimized Straight Flute: The classic straight twin-flute design provides excellent control and is exceptionally easy to resharpen, extending the overall lifecycle of the tool in busy workshops.
Premium HSS Material: Forged from high-quality High-Speed Steel, offering a perfect balance of toughness and wear resistance for continuous drilling in thin metals and tubes.
Multi-Step Efficiency (4-20mm): Features 9 clearly laser-etched steps (4, 6, 8, 10, 12, 14, 16, 18, 20mm), allowing operators to drill a wide variety of hole sizes with a single, quick-change tool.
Self-Starting Tip: The precision-engineered split point prevents walking and skating on smooth pipes and sheet metal, enabling instant, accurate starts.
