Know The Types of Hacksaw Blades and Its Various Applications A hacksaw blade is a handy cutting tool which should be user friendly and cut objects quickly and precisely. The hacksaw is used to cut steel and other metals. It can also be used to cut plastics, although it is not normally used to cut woods. It is sometimes called an adjustable hacksaw because the length of the frame can be altered to hold blades of different sizes. Blades are supplied in two lengths, 250mm and 300mm. If the adjusting screw is unscrewed, the frame can be pushed into the handle so that the smaller blades fit the hacksaw. Choosing a correct hacksaw blade with the right tooth per inch (TPI) and sturdy build is important to provide easy, straight and precise cutting. Given below are typical Hacksaw Blade Tooth/Inch (TPI) and their general usage.

Teeth Per Inch (25mm) 14TPI 18TPI 24TPI 32TPI

Suitable For Cutting Large Sizes, Aluminum And Other Sof Metals.

Suitable For General Workshop Cutting.

For Cutting Steel Plate Up To 5/6mm.

For Cutting Hallow Sections And Tubing.

Two types of hacksaw blade are generally available.

1. High Carbon Steel blades: Carbon is the hardest element and knife blades made from high carbon steel is no exception. The strength and hardness of the blade makes it ideal for edge retention which means less time required for edge maintaining the blade but since it does not have a drop of chromium, it has a very poor rust resistance capability. This means that you need to thoroughly clean the knife afer use and make sure that you guard it against moisture before you store it. There are a lot of professional chefs and survivalist that swears to the quality of high carbon steel blades but here is a short list of the advantages of having a high carbon blade.

Know The Types of Hacksaw Blades and Its Various Applications Sharpness: There is simply no matching the sharpness that high carbon steel blades have.

With skill and a lot of time, you can get a stainless steel knife sharp but not to the level that high carbon steel blades. That added level of sharpness allows you better precision in cutting and requires a lot less effort thus making the knife a lot safer.

Affordable: Of course, the price of a knife generally depends on various factors, but high carbon steel knives tend to be a lot more affordable than their stainless steel counterparts. I didn’t use the word cheaper because you might get the wrong idea. High carbon steel blades are cheaper in price, not in quality.

2. High Speed Steel: The main use of high-speed steels continues to be in the manufacture of various cutting tools: drills, taps, milling cutters, tool bits, gear cutters, saw blades, planer and jointer blades, router bits, etc., although usage for punches and dies is increasing.

High speed steels also found a market in fine hand tools where their relatively good toughness at high hardness, coupled with high abrasion resistance, made them suitable for low speed applications requiring a durable keen (sharp) edge, such as files, chisels, hand plane blades, and damascus kitchen knives and pocket knives.

High speed steel tools are the most popular for use in woodturning, as the speed of movement of the work past the edge is relatively high for handheld tools, and HSS holds its edge far longer than high carbon steel tools can.
