LENOX ® Band Saw Blade Construction

Terminology

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

Bi-Metal
The tooth tips are made of high speed steel that is electron beam welded to a high strength spring steel alloy backing material. The result is a durable, fatigue resistant blade able to withstand the heat generated when cutting steel and other alloys.

• Most metalworking applications
• Carbon steels
• Alloy and tool steels
• Stainless steels
• Nickel brass alloys
• Woodworking

Carbide Tipped
Solid carbide tooth tips are welded to a high strength spring steel alloy backing material. The result is a fatigue resistant blade which performs well cutting abrasive materials, tough to cut steels, nickel and titanium base alloys.

• Stainless steels
• Nickel base alloys
• Titanium alloys
• Abrasive materials
• Tropical Hardwoods

Carbide Grit
A tungsten carbide particle grit is metallurgically bonded to a spring steel alloy backing steel. This blade performs well cutting abrasive and difficult to cut materials that cannot be cut with ordinary band saw blades.

• Fiberglass
• Composite materials
• Formed glass
• Steel belted tires
• Chrome plated shafts

Carbon Flex Back
Constructed from one piece of carbon steel, with tooth hardness of Rc 64-66. Excellent fatigue life, even at high band speeds.

• Wood
• Plastics
• Abrasive materials
• Saws with band speeds in excess of 4,000 feet/min.

Carbon Hard Back
Constructed from one piece of carbon steel, with spring tempered back and tooth hardness of Rc 64-66. The stiffer backing material promotes straighter cutting and resists swaging and scoring of the band.

• Wood
• Plastics
• Abrasive materials
• Non-ferrous materials
• Saws with band speeds below 4,000 feet/min.
