Hacksaw Blade is used with fine tooth hand saw usually molded with as a metal arch handle, usually a Pistol grip, with screws for attaching a narrow disposable blade with it. Blade can be mounted on it with teeth facing towards or away from handle. Mostly hacksaw blade is used for cutting metals such as metal or plastics.
Hand-held hacksaws that cuts in pushing action, will result in increased tendency of blade to buckle and crack. While hack saw blade that cuts in pulling action will result in greater blade tension but higher controllability and longer blade life.
Various types of hack saw blades are such as all hard high speed steel blades, bi metal high speed steel blades, low alloy steel all hard hand hacksaw blades and junior saw blades and so on. Now Let us introduce you to each of these type of hack saw blades.
1. HSS ALL HARD
All hard high speed steel blade is most preferable when the subject is fully stable and is not subjected to extra blending and twisting stresses. The blade is uniformly hardened throughout. Due to its rigid and tough build, this kind of blade maintains hold on edges when dealing with alloys which are hard to cut, maintaining the straightness of cut. These are available in length of 10 and 12 inches.
2. Bi metal Flexible HSS
Bi metal flexible high speed steel blades deliver exceptional results for interrupted cuts and sawing in cramped places. As it is quite flexible, it can deal with situations in which blade has to face blending and twisting stresses. Due to tough and shock absorbing back and hardened high speed steel teeth they are shatter resistant also. Available sizes in this category are 10 and 12 inches.
3.LAS All Hard hand hacksaw blades and junior saw blades
Low alloy steel all hard blades are made with carbon steel. Mostly it is used to cut materials like aluminum, copper, brass, steel and so on. These are available in 6 inches, 10 inches and 12 inches size.
4.Vari tooth hacksaw blades
Vari tooth hacksaw have two blades in one and other benefits like less cutting cost. Large variety of applications, faster cutting, longer life, no lost in changing various TPI blades, reduced inventory of different TPI blade. Available sizes are 20 inches and 24 inches.
5.Power Hacksaw Blades
These are specially hardened and precise. It can be also produced specially for Kasto machines. They are designed to serve the highest requirements for power sawing bars, tubes, sections, etc.
6. Bimetal HSS
Bi metal high speed steel blade is made combining two different materials, body made with tough tool steel and tooth line with high alloy high speed steel. Due to this combination it has maximum wearing strength and cutting capability. And for the same, it is better than ordinary high speed steel blades. It can be specially produced for Kasto machines.
Selection of proper hack saw for whatever purpose depends on needs of your requirements in terms of size, application and charecteristics.
