HSS step drills are high-speed steel step drills, and their main uses include the following aspects:

 

One-time processing of multiple apertures: The stepped drill has multiple steps with different diameters, which can drill holes of multiple size in one drilling operation, without requiring frequent replacement of the drill bit like traditional drill bits, which improves work efficiency and is suitable for drilling on thin metal plates, plastic, wood and other materials.

 

No need for pre-drilling and central punching: The split tip design of the stepped drill allows it to have good self-centering capabilities and can easily cut into the material. In most cases, there is no need to carry out central punching or drill pilot hole in advance, reducing operating steps and improving drilling accuracy and efficiency.

 

Metal material processing: It can be used to drill holes in metal materials such as steel, brass, aluminum, and copper. It can process metal plates with a thickness of up to 3.2mm. It is often used in electrical, automotive, piping, sheet metal and other industries, such as drilling holes for repair parts in automobile maintenance, or making holes of various specifications in sheet metal processing.

 

Plastic and wood processing: It is suitable for drilling holes in plastic and wood, such as making installation holes in plastic sheets, or making connection holes for furniture in wood processing, and can maintain good surface quality during the drilling process.

 

Reaming and deburring: It can be used to expand the existing hole diameter to meet specific size requirements. At the same time, the cutting edge design of the stepped drill can trim the hole wall during the reaming process, reducing the generation of burrs and obtaining a smoother hole wall surface.

 

Making countersunk holes and countersunk holes: Some stepped drills can use their specific stepped shapes to make countersunk holes or countersunk holes while drilling. They are used to install countersunk screws and other parts to ensure the flatness of the surface of the parts. It is often used in the manufacture of electrical junction boxes, mechanical equipment, etc.
