Diamond Saw Works 125" Bandsaw Blades

Innovators Since 1890   

American Made Sterling Saw Blades by Diamond Saw Works.

Diamond Saw Works, Inc. got its start in Buffalo (my hometown), New York in the 1890s making hacksaw blades and saw machines.  Today Diamond Saw Works is an industrial supplier of high-quality metal and wood cutting saw blades.  Band saw blades account for 85% of their business and manufacturing effort.  The latest technology goes into the production of every Sterling® blade to ensure precise and consistent quality.

BLADE BASICS

• 1. Gage - The thickness of the blade.
• 2. Blade Width - The distance from the tip of the tooth to the back edge of the blade.
• 3. Set - The bending of teeth right or left to allow clearance of the back through the cut.
• 4. Tooth Back - The surface of the tooth opposite the tooth face.
• 5. Tooth Tip - The cutting edge of the tooth.
• 6. Tooth Face - The surface of the tooth on which the chip is formed.
• 7. Tooth - The cutting portion of the saw blade.
• 8. Tooth Rake Angle - The angle of the tooth face measured to a line perpendicular to the cutting direction of the saw.
• 9. T.P.I. - The number of teeth per inch.
• 10. Gullet - The curved area at the base of the tooth.
• 11. Gullet Depth - The distance from the tooth tip to the bottom of the gullet.
• 12. Blade Back - The body of the blade not including the tooth portion.
• 13. Tooth Pitch - The distance from the tip of one tooth to the tip of the next tooth.

Correct Tooth Selection

When the time comes to select the right number of teeth, try the following rule of thumb:

3 - 6 - 9 - 20

You should have a minimum of 3 teeth in the work at all times; having 6 to 9 teeth in the work is the optimum number; but more than 20 is too many teeth in the work.

There have been advances in blade design and manufacture, plus some testing results which tell us the following:

• A) When cutting mild materials on a bandsaw you should use the 3 - 6 - 9 - 20 formula.
• B) When cutting hard materials on a bandsaw, a few more teeth in the work piece will produce better blade life. This will not reduce the cutting time appreciably but will increase blade life.

Constant Pitch

The constant pitch tooth design is widely used for both cutoff and contour work and may be used for ferrous and non-ferrous materials. All constant pitch tooth configurations have a fixed number of teeth per inch.

Skip Tooth

The skip tooth design has greater gullet capacity for better chip clearance on softer metals, woods, plastics or composition materials. As the name implies, every other tooth is removed or skipped, without weakening the overall blade.

Hook Tooth

The hook tooth is similar to the skip tooth except the tooth face has a 10° rake angle which "hooks" or bites into the material more efficiently, and penetrates the material better, even at reduced feed pressures.

Blades in this common length other than what we stock can be ordered from the table below showing a stock number in the grid.  Numbers across the top header row indicate TPI of tooth count.

Proper Set Selection

Raker Set

Widely used on all types of blades and teeth. Its pattern is one tooth set left, one tooth set right with the third tooth straight or unset. This pattern allows for fast, efficient cutting and uniform saw kerf. Generally used on solids and thicker sections.

Wavy Set

Groupings of teeth are alternately set to the left and to the right, forming a wave pattern. Used for cutting thin or interrupted sections where tooth breakage or stripping is experienced. Because a group of teeth are set left, then right, the strain on each individual tooth is reduced.

E.T.S. (Every Tooth Set)

Each tooth is set alternately left, then right. Used generally in woodworking or for nonferrous metals. Also known as alternate set.

NOTE: Broach tooth and posi tooth blades are specially set to suit each tooth design. Their sets do not necessarily conform to any of the above descriptions.
