Precision HSS & TiAlN Spiral Flute Drilling for Clean, Controlled Hole Sizing

When accuracy & speed matter, Sutton Tools Step Drills are built to perform. These HSS & TiAlN spiral-flute step drills deliver clean, chatter-free cuts through stainless, mild steel, aluminium & plastics. Designed for trade professionals who demand durability & precision, each bit provides smooth transitions between steps for consistent hole sizing & reduced rework.

Manufactured from High-Speed Steel (HSS) & enhanced with TiAlN coating, these step drills maintain sharpness under heat, cutting faster & lasting longer. Spiral flutes clear chips efficiently while minimizing vibration, ideal for electricians, fabricators & maintenance crews using cordless drills, drill presses, or CNC machines.

For the best performance, pair your step drills with Drill Accessories to ensure precise pilot drilling. Maintain edge life with Drive Lubrication Systems that reduce friction & heat during extended drilling. Verify measurements with Measuring & Layout Tools & rely on Same Day Dispatch from Industrial Shed to keep your projects moving.
