HSS Step Drill ø 6-30 mm, Stroke 2 mm, Handle ø 10 mm (5904012136052)

The HSS step drill is a very useful product. It is suitable for professional use in industry, metalworking, and construction. It allows for drilling holes of selected diameters, enlarging existing ones, creating preliminary points for further processing, and even milling edges. It is equipped with a cylindrical holder that can be attached to the chuck of a drill, screwdriver, or even some milling machines. The STALCO PERFECT HSS step drill is made of HSS high-speed steel. The ground spiral flute reduces vibration, resulting in precise work. It also facilitates rapid chip removal. Thanks to the axial grinding of the workpiece, the drill leaves very smooth edges. STALCO offers step drills in three variants, which differ in the drill diameter range, pitch, and shank diameter.
FEATURES AND ADVANTAGES
Ground, sharp edges speed up work and reduce the time needed to complete it.
Fast removal of drilling dust speeds up work and reduces the time needed to complete it.
Long product life reduces costs

Step drills, as the name suggests, have different steps that cut the desired diameter, and this is what distinguishes them from other types of drills.
They enable the economical production of holes of various diameters with a single tool.
For HSS step drills, grinding oil, drilling and cutting oil, or compressed air should be used as a coolant or lubricant. For uncoated HSS drills, the use of a coolant is required.
