Product Features
- Hard material: Metal hole openers are generally made of high-speed steel, cemented carbide and other materials. These materials are hard and wear-resistant, can withstand large cutting forces, ensure that the cutting edge is not easily damaged during the hole opening process, and can be used for a long time.
- Multiple blade designs: There are multiple blade types such as serrated blades and twisted blades. The serrated blade can effectively cut metal sheets and remove chips smoothly when opening holes; the twisted blade hole opener is more suitable for drilling holes in thicker metal materials, and the drilling process is relatively stable.
- High precision: After precision processing during the manufacturing process, the dimensional accuracy is high. This makes the hole diameter accurate and the hole wall smooth, which can meet the needs of operations with high precision requirements.
- Diverse specifications: There are different diameter specifications, from smaller diameters for opening small holes to larger diameters for opening large holes, which can meet various metal hole opening needs, such as opening small installation holes on thin metal plates, or opening large holes for pipes on thick metal plates.
Uses
- Industrial manufacturing: used to make holes in metal parts, equipment housings, etc. in mechanical manufacturing, such as holes in machine tool housings for installing wire ducts, and holes in metal brackets for connecting other parts.
- Construction industry: used to make holes in metal structural building materials, such as holes in beams and columns of steel structures for installing bolts, threading wires, etc.; also used to make holes in metal frames when installing metal doors and windows.
- Electrical installation: holes are made in metal plates of electrical control cabinets and distribution boxes for installing switches, sockets, wire connectors and other electrical components.
- Automobile repair and modification: holes are made in metal parts such as automobile bodies and engine parts (where permitted), such as installing car audio, additional heat dissipation devices, etc.
