Set of 3 HSS Step Drill Bits (5904012136069)

HSS step drills are a very useful product. They are used in professional applications in industry, metalworking, and construction. They allow you to drill holes of selected diameters, enlarge existing ones, create preliminary points for further processing, and even mill edges. They are equipped with a cylindrical shank that can be attached to the chuck of a drill, screwdriver, or even some milling machines. STALCO PERFECT HSS step drills are 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 element, the drills leave very smooth edges. The set includes three drills made of HSS high-speed steel. The drills vary in diameter range and pitch. All three drills are supplied in a durable plastic case for safe storage.

PROPERTIES
The HSS step drill is a strong, high-performance
A tool for burr-free drilling and deburring of sheet metal, pipes, and profiles, etc.
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 economic 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.
