Q: How to Change Bandsaw Blades

If you need to change your bandsaw blade, it can be challenging to determine where to start. Our guide will walk you through the removal and installation processes, so you can change your blade efficiently and get back to using your bandsaw. READ MORE

Q: Top 11 Benefits of Circular Saw Blades

Are you still trying to find that blade that gives you fast and accurate cuts with outstanding blade life and surface finish?

Then you’ll need the right tools for the job.

Introducing DoALL circular saw blades. Cermet and coated carbide circular saw blades are steel saw bodies with tungsten carbide or cermet brazed to them.  DoALL’s blades are the top choice of professionals in manufacturing and fabrication. Offering a wide variety of blades for every high production application, DoALL is the brand of blades you can always depend on. READ MORE

Q: What kinds of band saw blades are available?

Toothed blades are most widely used, but there are other types. Knife edge blades slit soft, low density materials with little or no mess. Grit edge blades cut very hard, brittle, or abrasive materials.

Q: How do I choose between Carbon Steel, Bi-Metal, and Tungsten Carbide blades?

  • Carbon steel blades are usually the best choice for sawing wood, plastic, aluminum, and similar easy-to-cut materials.
  • Bi-Metal blades have the best balance of heat resistance, wear resistance, and chip resistance to productively saw most steels and other metals.
  • Tungsten Carbide blades provide superior heat and wear resistance for sawing extremely tough metals or very abrasive metals and non-metals.

Q: What exactly is a Bi-Metal blade?

These blades begin as a bi-metal strip produced by electron- or laser-beam welding a narrow strip of high speed steel to a wider strip of alloy steel. Teeth are cut into the high speed steel edge. The resulting blade has highly heat and wear resistant teeth and a tough, durable backing.

Q: Why are there so many different Bi-Metal blades?

DoALL Bi-Metal blades include three different high speed steel edge materials and six different tooth forms.  Each style was designed for a specific application.  For help in making a selection, contact us.

Q: What blade pitch should I use?

In most cases, the blade should engage somewhere between six and 24 teeth in the work. Engaging fewer than three teeth can cause tooth shock and stripping. Engaging too many teeth reduces cutting rates and may lead to tooth stripping due to overfilled gullets.

The DoALL blade catalog includes a pitch selector. To request a catalog, call (888)362-5572 x 12009.

Q: How and why do I break in a saw blade?

Breaking in a new band saw blade hones and strengthens ultra-sharp cutting edges and significantly increases band life.

To break in a bi-metal saw blade, run at the recommended band speed, but reduce the normal cutting rate by about half. (Make sure the band keeps pulling chips. If necessary, increase the feed force until the band does pull chips.) Cut at this reduced rate for about 20 minutes, and then increase the feed force in steps until you attain the normal cutting rate.

To break in a carbide blade, reduce both the band speed and cutting rate by 50% and begin sawing. Increase the band speed and feed force in small steps, but never allow the band to squeal or shriek.

Q: I keep stripping teeth in my saw blade. Why?

Check the blade pitch. If the blade engages fewer than six teeth, those teeth are subject to overloading and stripping, especially under heavy feed force. If the blade engages more than 24 teeth, the chips formed may pack the relatively small gullets and strip teeth.

Any chips drawn back into the cut contribute to gullet packing and stripping. Cutting fluid must prevent chip welding, and the chip brush must clean the gullets as the blade exits the cut.

A workpiece that spins or moves in the saw vise will destroy a blade abruptly.

Revolutionizing the Sawing Industry

DoALL® Sawing Products is the original manufacturer of metal-cutting industrial bandsaws and continues to be an industry leader after more than 97 years. Our company was started by Leighton A. Wilkie in Minneapolis, Minnesota, in 1927. He invented and manufactured the first metal-cutting bandsaw only six years later.

We have continued to preserve the legacy since then, producing industrial saws that raise the bar for innovation and quality. We're proud of our history as top-of-the-line industrial bandsaw manufacturers. We have accomplished many milestones since DoALL's establishment, such as creating the first:

  • Invented the original metal cutting band saw blade
  • High-friction sawing bandsaw blades.
  • Microprocessor-controlled automatic sawing system.
  • Automatic cold saw.
