Cutting Fluids

Excessive heat, entry shock, and high-speed abrasion are the top three blade destroyers, causing bandsaw blades to prematurely wear and fail. Shortened blade life causes expense by having to spend more money purchasing new blades. To help protect bandsaw blades from early fail, and to help save time and money, it is recommended that bandsaw operators use cutting fluid. Cutting fluid can mean coolant or lubricant. The terms are indiscriminate now and used to describe either coolant or lubricant. They are used to dissipate heat on a saw blade as it works its way through the material, providing a coating or lubricant to the blade — increasing blade life, protecting the …

Bandsaw Vise / Vise Clamp Use

Vises or vise clamps are used in every bandsaw operation:  woodworking, metalworking, and for cutting various objects. Both vise and clamp are used to describe the same thing, but technically, a vise clamp refers to a portable or hand-held clamping tool and a vise refers to a bench-mounted clamp. Both serve the same significant role in the cutting process: to hold materials in place, allowing work to be performed. They are particularly useful in cutting irregular or curved shapes but can also be used to produce straight cuts. They perform better at steady hold than flesh & bone hands, making it a safer bet as well. Vises are versatile enough …

Bandsaw Blade Speed Rates

Bandsaw blade speed is describe as the travel of the bandsaw blade across the material face being worked. This is expressed in surface feet per minute (SFPM). Bandsaw blade speeds range from 40 feet per minute to 5,000. It is important to remember that different materials require different blade speeds. For metal, typical blade speeds range from 60- to 300sfm. There are specialized bandsaws built to cut harder metals and require a speed greater than 300sfm. Woodworking bandsaws run at speeds between 1,00o- to 8,000 feet per minute. 3,000sfpm is the general speed. The blade speed rate depends on the …

Saw Blade Stripping and Breakage

Stripped bandsaw blade teeth is a common problem, and there are several causes to consider. A big factor includes use of the incorrect tooth pitch. Too small teeth for the size of the material fills gullets halfway through the cut. Pressure builds on a single tooth until it breaks and becomes lodged in the cut. Now the other teeth come in contact with the broken tooth, resulting in more broken teeth. Follow the m.o.m. rule: Minimum, Optimum, Maximum, which requires a minimum of 3- and a maximum of 24 teeth engaged in a cut in order to achieve the best …

Bandsaw Blade Tracking

Knowing how to properly track a bandsaw blade is important and something every bandsaw operator should have basic knowledge in performing. A blade needs to be properly tracked in order to ensure a smooth operation, secure operator safety, and to keep the bandsaw running optimally and smooth. It would be a waste of time and money to cut materials without first tracking the saw blade. Without it, crooked cuts result, equating to wasted materials. Damage to the machine or the blade after it pops from the wheels is likely to occur. There is also the risk of personal injury to …

D2 Steel and the Bi-Metal Bandsaw Blade

D2 steel is a type of vacuum heat treated steel that is raised to a high temperature and then rapidly cooled by vacuum process. An air-hardened steel composed of a large amount of carbon and chromium, with a high chromium content that gives D2 its mild corrosion resistance properties. Typical applications include forming dies and rolls, punches, knives, shear blades, scrap choppers, and tire shredders. D2, Inconel, and other exotic materials are considered very hard steels and require the use of a saw blade designed exclusively for these materials. Bi-metal blades work best. The 601 Series Haltbar M42 bandsaw blade is widely …

Carbon Bandsaw Blades

Choosing the right bandsaw blade for the job depends on the materials to be cut, and understanding the reasons why one blade is best over another will help to assure prolonged blade life. It will depend on the type of bandsaw, its current condition, the materials to be cut, and how they will be cut. Relying on one blade for every purpose won’t work and isn’t a good idea, especially if cost factors are an issue and quality is a goal. It is impossible for one blade to serve every purpose, so to assure that the perfect blade is being utilized, and to achieve optimum …
