(Summary description)Scope of application: wood, composite building board, plastic, synthetic resin, aluminum, cast iron less than 10mm, steel less than 5mm. The above materials generally have a hardness of less than 50 degrees, so it is recommended to use a bimetal hole opener. M42 bimetal has the characteristics of not easy fracture and high abrasion resistance. Therefore, it is recommended to use bimetal hole opener when encountering the above materials.

Information
1. Bimetal hole opener
Scope of application: wood, composite building board, plastic, synthetic resin, aluminum, cast iron less than 10mm, steel less than 5mm. The above materials generally have a hardness of less than 50 degrees, so it is recommended to use a bimetal hole opener. M42 bimetal has the characteristics of not easy fracture and high abrasion resistance. Therefore, it is recommended to use bimetal hole opener when encountering the above materials.
2.Special openings for pipes
Scope of application: fire-fighting pipes, water pipes, shipbuilding, steel structure bodies, cast iron over 10mm, steel over 5mm.
The above materials are generally more difficult to make holes than ordinary materials. Therefore, it is recommended to use imported saw blades with a hole depth of 35mm or 48mm for the above materials. In the process of use, the service life of the pipe-specific hole opener is significantly longer than that of ordinary bimetal hole openers.
3. High speed steel hole opener
Scope of application: sheet metal, iron plates, stainless steel plates or round pipes below 5mm.
The high-speed steel has good process performance, good strength and toughness. Common high-speed steel openers are mainly made of 42, 43, 93, 65 grade materials. High-speed steel is also divided into integral and welded. More stable than welded high speed steel. Because the alloy hole opener is easy to get stuck when operating with a pistol drill, it is recommended to use a high speed steel hole opener when encountering a round pipe.
4.Alloy opener
Scope of application: iron sheet, iron plate, stainless steel plate, etc.
