HACKSAW BLADE
1. By tooth pitch
Can be divided into coarse tooth saw blade, medium tooth saw blade, fine tooth saw blade three, tooth pitch is to 1 inch length contains the number of teeth, the more teeth, the finer the tooth pitch, coarse tooth saw blade generally 14-16 teeth, medium tooth saw blade generally 18-22 teeth, fine tooth saw blade generally 24-32 teeth.
2. According to the material
( 1 ) bimetal saw blade: the saw blade welded by two metals, specifically by the carbon steel body and high-speed steel saw teeth. Used for cutting pipe, solid body, wood, plastic and all machinable metal. Higher resistance to heat and abrasion and longer life than monometallic saw blades. High flexibility to avoid breakage and breakage in the cutting process.
(2) Carbide saw blade: used for cutting glass, hardened steel, stranded fiber and tile. It is super resistant to heat and abrasion and can cut all the substances that other saw blades or saw blades cannot cut. Its cutting carbide up to 300mm / min, cutting marble up to 100mm / min, cutting diamond up to 40mm / min, is the traditional reciprocating saw or line cutting efficiency of dozens of times, its narrow kerf (only 1.2mm ~ 2mm), compared with the traditional reciprocating saw and circular saw can save raw materials 6 ~ 10 times.
(3) high-speed steel saw blade(HSS saw blade): for cutting pipe, solid body, wood, plastic and all machinable metal. The hardness of the saw blade is higher than other high-speed steel. Flexibility, very suitable for use with a small tension saw frame. The center of the back of the band is not hardened to avoid breakage during the cutting process.
(4) Carbon steel saw blade: used for cutting pipe, solid body, wood, plastic and all machinable metal. Low cost, more general.
