Owner’s manual
How do I know the size of my bandsaw blade?
For your Craftsman 113247410 12-inch electric band saw, blade size means length, width, and TPI (teeth per inch). The manual confirms the saw comes with a 1/4-inch wide blade and accepts 1/8-inch to 1/2-inch blade widths; you can measure length directly from your existing blade. See the owner's manual for blade installation and alignment details.
What to measure (the 3 blade specs)
- Blade length: the total loop length of the blade.
- Blade width: measure from the tooth tip to the back edge of the blade.
- TPI (teeth per inch): count how many teeth fall in 1 inch; this affects cut speed and smoothness.
How to measure blade length safely and accurately
- Unplug the saw and remove the switch key before touching the blade.
- Remove the blade and coil it carefully.
- Lay the coiled blade flat on the floor.
- Pick a reference point (the weld is easiest), mark it with tape.
- Use a tape measure and roll the blade along its edge until the mark returns to the start; that distance is the blade length.
Safety notes that matter on this model
The manual’s safety guidance is specific: do not wear gloves around the blade (gloves can get caught). Wear eye protection and keep the saw unplugged during blade changes and adjustments. Refer to the owner's manual for the full blade-change procedure and guide/bearing adjustments.
Blade width guidance for Craftsman 113247410
The manual confirms these width limits and common uses:
| What you’re doing | Typical blade width to use | Why it helps |
|---|---|---|
| Curve cutting | 1/8 in to 1/4 in | Turns tighter without binding |
| General cutting (crosscut, miter, bevel) | 1/4 in to 1/2 in | Balanced control and stability |
| Resawing | 1/2 in | Straighter cuts in thicker stock |
Why it matters
Using the correct blade size helps the blade track on the rubber tires, keeps the guides and thrust bearings adjustable in the right range, and reduces blade breakage. It also improves cut quality in wood, wood-like materials, and plastic.

What is the 3-tooth rule for bandsaws?
The 3-tooth rule means choosing a band saw blade tooth pitch (TPI) so at least 3 teeth are in the cut at all times. On the Craftsman 113247410 12-inch electric band saw, this reduces tooth snagging, improves chip clearance, and helps the blade cut smoother; see the 113247410 owner's manual.
How to apply the 3-tooth rule
- Measure the material thickness in the direction the teeth travel through.
- Choose a TPI that keeps 3 or more teeth engaged.
- For thin stock, use a finer TPI; for thick stock or resawing, use a coarser TPI.
- If the cut chatters or grabs, increase TPI; if the kerf packs with sawdust, decrease TPI.
TPI starting points (common shop guide)
| Material thickness | Typical TPI range |
|---|---|
| 1/8 to 1/4 inch | 14 to 24 |
| 1/4 to 1/2 inch | 10 to 14 |
| 1/2 to 1 inch | 6 to 10 |
| Over 1 inch | 3 to 6 |
Setup checks that protect the blade
Your manual emphasizes adjustments that directly affect blade life and cut quality:
- Set upper and lower blade guides so they sit about 1/32 inch behind the deepest part of the teeth (the gullet) so teeth do not hit the guides.
- Confirm the blade tracks near the center of the upper wheel tire when turning the wheel by hand.
- Use correct blade tension; too much tension contributes to blade breakage.
- Match blade speed to the work; this saw uses 3000 FPM for basic wood cutting and 1500 FPM when more control is needed.
Why it matters
With fewer than 3 teeth engaged, each tooth takes too much load and can strip or break. With the right engagement, cutting forces spread across multiple teeth and gullets clear sawdust efficiently.

What is the specs of the Craftsman 12 inch bandsaw 113247410?
The Craftsman 113247410 is a 12-inch electronic band saw. It has a 12-inch throat capacity, 6-inch maximum cutting height, a 23 x 27 inch table with 0 to 45 degree tilt, and a 120V single-phase motor rated 5/8 HP (1-1/8 max developed) at 1725 RPM; see the 113247410 owner's manual for the full spec list and setup details.
Key specifications (model 113247410)
- Throat capacity: 12 inches
- Maximum cutting height (resaw capacity): 6 inches
- Table size: 23 x 27 inches
- Table tilt: 0 to 45 degrees
- Electrical: 120V, single phase
- Motor: 5/8 rated HP (1-1/8 max developed), 1725 RPM
Quick spec table
| Spec | What it affects | Why it matters |
|---|---|---|
| 12-inch throat | Max workpiece width | Helps you plan cuts on wider stock |
| 6-inch cutting height | Resaw thickness | Determines the thickest material you can cut |
| 23 x 27 inch table | Work support | Improves stability and accuracy |
| 0 to 45 degree tilt | Bevel cuts | Enables angled cuts without jigs |
| 120V, 1-phase | Power requirements | Confirms standard household circuit use |
How we recommend using these specs
- Match blade selection to the cut type (straight vs. curves) and your material.
- Set blade tension and tracking before cutting; correct setup reduces drift.
- Use the table tilt scale for rough angles, then fine-tune with a square or gauge.
- Confirm your outlet and circuit match 120V single-phase before installation.
Why it matters
These specs determine what the saw can physically cut (capacity), how accurately it can cut (table size and tilt), and how it should be powered and set up (motor and electrical ratings). For diagrams and part identification, you can also search by model number on Sears PartsDirect.
