Preventing Weld Breaks

There are ways to prolong bandsaw blade life and avoid weld breakage. All bandsaw blades are welded or soldered. A strip of teeth are cut to length and welded to make a loop. Sometimes, the saw blade will break at this weld. A break is the result of an improper weld, or that there is too much tension on the bandsaw wheel, or even that a bad quality blade predisposed to such a break was purchased. Weld breakage is common, and questions a vendor may ask include whether or not proper blade tension was applied, what size and type of material was being cut, and had …

Exotic Metals

The term exotic metals is used to describe any metal that has special qualities, a degree of rarity, or an unusual type of material use in manufacturing. Exotic metals are typically nonferrous and include things like Aluminium, Nickel, Chromium, Cobalt, Copper, Hastelloy, Inconel, Mercury, Molybdenum, Monel, Platinum, Stainless, Tantalum, Titanium, Tungsten or Wolframite, and Waspaloy. Exotic Materials can also include plastics, superalloys, semiconductors, superconductors, and ceramics. Because of their unique properties, exotic metals are used in specific engineering applications like industrial and marine applications, casting, chemical processing industries, pulp and paper, aerospace, nuclear engineering, heat treating industries, aerospace, and for electronic components, chemical equipment, missile technology, and nuclear reactors. Exotic material …

Carbide Bandsaws and Blades

Carbide Bandsaw Blades are derived from the carbide saw, a name that originated from a circular saw blade with silver soldered carbide tips. Other names include cold cut, cold circular, cold cut-off, and circular cold saws. The carbide blade nearly replaced solid or segmented high-speed steel (HSS) blades since carbide is much harder than HSS. HSS blades use coolant to keep the surface from over-heating, but the carbide circular saw has a unique geometry of teeth that allows for heat developed during the cutting process to be transferred to and then carried away with the chips. The most common type of carbide …

Variable Pitch Bandsaw Blades

The variable pitch bandsaw blades, their unique qualities and applications, are designed for a particular reason. In this case, it is pitch. Saw blade pitch is defined as the number of teeth per inch — TPI — the number of teeth that come in contact with the material being worked. TPI has the ability to affect both the bandsaw blade’s performance and it durability. Too few teeth in the cut can lead to early stripping of the teeth. Conversely, too many teeth in a cut will greatly reduce the cutting rate and ultimately make the material impossible to cut. The choice of correct …

All About TPI (teeth per inch)

Here at Sawblade.com, questions arise with regard to perceived saw blade problems. After a few inquiries, it can be determined if the machine operator made any miscalculations with speed and feed, the materials being cut, TPI, and any other variable that ends up impacting the cutting process. In most cases, the customer already knows exactly what is needed. The operator knows the blade size, length and width, the thickness of the blade being ordered, and they know the materials to be cut so there is often no need to ask about carbon, bi-metal, or carbide blades or the proper tooth pitch required for that particular job. There …

Measuring Saw Blades Without Cutting

Measuring Saw Blades Without Cutting — Like many items that may have been procured second-hand or a long time ago, the chances of having the owner’s manual that came with the piece is usually slim. If that is the case, then today’s post should offer a bit of help meant to help explain how measuring a bandsaw blade without the need for cutting. For bandsaws that have been in use for awhile, the actual length of that blade can be a tricky number to determine. However, with a little bit of measuring, the number is easier to find than one might think. Here are the steps …
