Drillco U Slow Helix 135 Degree Drill (720A521)
Drillco 720A521 U Slow Helix 135° Drill is engineered for precision, strength, and reliable performance in demanding drilling operations. Its slow helix design with a 135° split point ensures easy penetration, enhanced edge strength, and reduced walking when starting holes. The heavy-duty web, short flute, and overall length provide superior rigidity and stability, making it ideal for drilling hard materials up to Rc 60. Constructed from solid carbide, this drill delivers long-lasting cutting performance and durability for professional machining tasks. The formulation uses inert, non-carbonizing, and nonhazardous ingredients, making it safe and highly resistant to water, seawater, benzene, and most acids and alkalis. It performs reliably across a wide temperature range from -30°C (-22°F) up to 1400°C (2500°F).
