US PRO 7136 5pc HSS-G+ Step Drill Set 4 to 35mm in Case

The US PRO 7136 5pc HSS-G+ Step Drill Set is made for the kind of work where neat, accurate holes matter and time is tight. Instead of swapping drill bits every time the hole size changes, step drills let you open out the diameter gradually, keeping control in thin materials and helping you achieve a cleaner finish.

Each drill in this set is manufactured from quality HSS-G+ high speed steel and heat treated for increased hardness, making it a dependable choice for regular workshop and site use. The set is particularly well suited to drilling in non-ferrous metals, sheet metal and PVC, where controlled cutting and reduced snagging are essential.

Supplied in a protective case, the drills stay secure, easy to find, and ready to grab when you’re moving between jobs.
