How to Choose the Correct Number of Teeth Per Inch (TPI)
The number of teeth per inch (TPI) is important in obtaining the finish desired and the proper feed rate. A coarse tooth blade (1, 2 or 3 TPI) should be used for re-sawing wood and cutting thicker stock. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4". For general cutting of 3/4" plywood 4 or 6 TPI will provide a fast cut and 14 TPI will cut much slower but leave a smooth finish on the cut. As a general rule, try to have 3 to 12 teeth in the work for general cutting. Bandsaws designed to cut wood runs at 2700 to 3200 band feet per minute (BFPM), while bandsaws that cut metal are designed to normally run between 75 and 350 BFPM. If using a wood cutting machine to cut metal, it is recommended to use blades made of bi-metal Diemaster 2 stock for longer life of the blade, as carbon steel blades (NT & FB) will have a very short life. If your intent is to do a lot of metal cutting or the major use of the saw is for cutting metal, it is recommended that a metal cutting saw be used.
When Selecting TPI Remember:
When you want to cut metal, it is suggested you use bi-metal Diemaster 2 blades for longer blade life.
More TPI gives a smoother but slower cut. Fewer TPI allows for a faster cut with a slightly rougher cut surface. Should have at least 3 teeth and less than 12 teeth in the work piece.

Type of Blade Materials
NT = NEO_TYPE
The body of this blade is heat treated for extra stability while cutting Recommended for use at band speeds less than 4,000 feet (1,200 meters) per minute.
FB = FLEX BACK
Excellent Fatigue Life - Designed to cut a wide variety of materials Flexible carbon steel is very durable even at high band speeds—up to15,000 feet (4,500 meters) per minute
DM= DIEMASTER 2
Runs at twice the speed of carbon blades for faster, easier cutting, longer blade life - Lasts 6 times longer than carbon blades. M-42 high speed steel edge for excellent heat and wear resistance.
C = CLASSIC Designed for long life in general cutting applications. M-42 high speed steel edge for excellent heat and wear resistance
WMB = WOODMASTER B Designed for
extended life and speed when cutting exotic or difficult to cut woods
,
M-42 high speed steel edge for excellent heat and wear resistance.
TM = TRI-MASTER PRECISION TRIPLE CHIP GRIND Smooth cuts, excellent finish, Excellent fatigue life.
WMCT = WOODMASTER CT Precision ground carbide tips provide smooth, precise finish. Provides extended life and speed when cutting exotic or difficult to cut woods.
