US PRO 2645 3pc HSS Step Drill Set Titanium Coated 4 to 30mm

The US PRO 2645 3pc HSS Step Drill Set is built for those jobs where you need multiple hole sizes in thin materials without stopping to swap bits. Whether you’re working on panels, brackets, enclosures, or plastic sheet, these step drills let you open out holes gradually with better control and a cleaner finish.

Manufactured from quality HSS high speed steel and heat treated for increased hardness, each drill is titanium coated to help reduce friction and improve wear resistance during regular use. The 118 degree split point helps the drill start more confidently, reducing wandering and making it easier to keep holes accurate, especially on smoother surfaces.

This set includes three step drills with overlapping ranges, so you can handle small pilot sizes through to larger clearance holes up to 30mm using the right tool for the job.
