Craftsman 10 Band Saw Blade: TPI, Material, and Cut Compatibility
You own a Craftsman 10-inch band saw and you need to order replacement blades. The 10-inch saw uses a 70-1/2 inch blade, but you see multiple width, TPI, and material options. You want to know which blade produces the best results for your work. You need a guide that covers the blade options and helps you choose the right one.
The Craftsman 10-inch band saw uses a 70-1/2 inch blade. This is a standard length available from Olson Saw, Timber Wolf, and other manufacturers. The blade width, TPI, and material you choose affect cut quality, blade life, and the types of cuts you can make.
Blade Length and Fit
The Craftsman 10-inch band saw uses a 70-1/2 inch blade. This is the correct length for the 21400 series and similar 10-inch Craftsman models.
Important: Always verify the blade length with your saw’s manual or by measuring the old blade. Some 10-inch saws use 62 or 72 inch blades.
How to Verify Blade Length
- Check the manual for the specified blade length.
- Look for the blade length printed on a label inside the wheel cover.
- Remove the old blade and measure it.
- Look up the model number on Sears Parts Direct.
Cross-Brand Compatibility
The 70-1/2 inch blade is used by other 10-inch saws that share this length. Blades from Olson Saw, Timber Wolf, and other manufacturers will fit the Craftsman 10-inch saw.
Blade Width Options
The Craftsman 10-inch band saw can accommodate blades from 1/8 to 1/2 inch width.
1/8 Inch (14 TPI)
Best for: Tight curves and scroll work. Minimum turning radius about 2 inches. Not for: Straight ripping, resawing, or thick stock.
1/4 Inch (6 TPI)
Best for: General curve cutting. Minimum turning radius about 4 inches.
3/8 Inch (4 TPI)
Best for: The best all-around width. Tracks straight for ripping and crosscutting. Still handles curves with a 5 inch radius or larger. If you only buy one blade, make it 3/8 inch with 4 TPI.
1/2 Inch (3 TPI)
Best for: Straight ripping and light resawing. Will not cut curves tighter than about 12 inch radius.
TPI Selection
| TPI | Best For | Stock Thickness |
|---|---|---|
| 3 TPI (hook) | Resawing | 3+ inches |
| 4 TPI (skip) | General woodworking | 3/4 to 2 inches |
| 6 TPI | Smoother cuts | 1/2 to 1 inch |
| 10 TPI | Thin stock | 1/4 inch and under |
| 14 TPI | Scroll work | 1/4 inch and under |
Rule of thumb: At least 3 teeth should be in the material at all times.
