Band Saw Blades

Through the last 13 years that Bi-Metal Industrial Products Inc. has been in business, we have had a lot of questions about band saw blades and how to run this particular tool on the machines they are designed for. We sell a wide range of blades from small ¼” carbon band saw blades to the large 3” Carbide.

We have found that operator, machine and material in this order have a direct correlation to the success of how a cutting job is going to be.

A lot of shops we have found, never really pay too much attention to the cutting process until something goes hay wire. That’s when we get calls.

The BAND SAW operation is one of the most crucial operations in a machine, fabrication or mill shop because it is the first, operation. If material doesn’t get cut no work can continue on a particular part.

Some planning is required:

1. Type and Size of Material to be cut

2. How many pieces

3. Type of machine

4. Who is cutting material

Today we will look some of the above items.

1. Check and make sure your machine can handle the job. Some machines have a large capacity but not the horse power. Eg. 7” x 12”machine running a 1HP motor with a 3/4” x .035 x --- x 7’9” blade is not capable of cutting a 7” round bar.

2. You need to know the grade, shape, hardness, size and is material to be bundled.

3. Determine the proper number of teeth per inch and tooth form. Here is a simple rule to consider. 3 to 24 teeth on the largest cross section of your work piece and the harder more brittle materials and smaller cross-sections the tooth form raker tooth or skip tooth is more favorable, eg. Mild steel materials.

4. Tooth forms with positive rake are useful for long–chipping and ductile material, eg. Stainless materials.

5. Look at your Cooling lubricant also, is water soluble sufficient or do you need to go to semi or fully synthetic or even a wax.
