Are all table saw arbor nuts the same size?
No. Arbor nuts are not universal; the thread size and direction (right-hand or left-hand) depend on the saw’s arbor design. For a Craftsman 11327580 8" tilting arbor bench saw, you must match the nut to the arbor threads and the flange stack so the blade clamps securely.
Even when two saws use the same blade bore, the arbor nut can still be different.
- Thread diameter and pitch (for example, 5/8-inch arbors are common on many 10-inch saws, but not guaranteed)
- Thread direction (some saws use left-hand threads so rotation helps keep the nut tight)
- Nut style (hex nut vs. flange nut, thickness, washer face)
- Arbor length and washer/flange setup (changes how much thread engagement you get)
- Brand and model-specific hardware (Craftsman, Ridgid, Delta, etc. can vary)
Use these checks to avoid cross-threading or a blade that will not clamp flat.
- Unplug the saw and remove the throat plate.
- Remove the blade and inspect the arbor threads for damage or flattening.
- Thread the nut on by hand only for the first few turns.
- Confirm the nut seats fully and clamps the outer blade washer/flange evenly.
Typical patterns help, but the arbor threads are what matter.
| Saw/blade category | Typical blade bore | Arbor nut universality |
|---|---|---|
| Many 10-inch table saws | 5/8 in. | Not universal (threads and direction vary) |
| Many 12-inch saws | 1 in. | Not universal |
| Benchtop/compact saws | Varies | Not universal |
The arbor nut is what keeps the blade clamped to the arbor. If the nut is the wrong thread, wrong direction, or wrong thickness, the blade can wobble, slip, or fail to tighten correctly, which affects cut quality and safety.
- For ordering the correct hardware, confirm the full model number on the saw’s ID tag and use how to find your appliance model number (and what it means for parts).
- If you suspect electrical damage while troubleshooting the saw (switch, cord, motor leads), use how to use a multimeter to test electrical parts video for basic testing technique.

Can you use an 8 inch blade on a 10 inch table saw?
Yes, you can use an 8-inch blade on a 10-inch table saw, including the Craftsman 11327580 8-inch tilting arbor bench saw, as long as the blade’s arbor hole matches your saw and the blade is rated for the saw’s RPM. Expect reduced maximum cut depth compared with a larger blade.
- Arbor size (center hole): The blade bore must fit the saw’s arbor shaft.
- Blade speed rating: The blade’s max RPM rating must meet or exceed the saw’s no-load speed.
- Kerf and plate thickness: Make sure the blade clears the throat opening and doesn’t rub the insert.
- Blade type for the job: Rip, crosscut, combination, or dado (if your setup supports it).
- Guard and splitter/riving knife fit: Smaller blades can change how the guard aligns.
Using a smaller diameter blade mainly affects cutting capacity and sometimes dust collection and guarding alignment.
| Blade diameter | Typical max cut depth at 90° | Best use case |
|---|---|---|
| 10-inch | About 3-1/8 inches | General purpose, deeper cuts |
| 8-inch | About 2 inches | Thinner stock, finer control |
Many 8-inch dado sets are designed to be used on 10-inch saws because dado cuts are non-through cuts. If you plan to run a dado stack, confirm your arbor length, flange clearance, and that your setup supports dado use.
Blade diameter affects cut depth, and mismatched arbor size or an under-rated RPM blade can cause vibration, poor cut quality, or unsafe operation. Matching the arbor and speed rating keeps your Craftsman saw cutting smoothly and safely.

How to get rid of an old table saw?
If your Craftsman 11327580 table saw still runs and the arbor tilts and raises smoothly, the best way to get rid of it is to sell or donate it; if it is unsafe or incomplete, recycle it as scrap metal and dispose of sharp blades separately so nobody gets hurt.
- Sell it if it powers on and the blade height and tilt adjustments work.
- Donate it if it is complete (guard, fence, miter gauge) and reasonably safe.
- Give it away for parts if the motor runs but the saw is worn or missing accessories.
- Recycle as scrap metal if the frame is damaged, the arbor is bent, or it is not worth repairing.
- Dispose of blades safely (see below) instead of tossing them loose in the trash.
Before moving the saw out of your shop or garage:
- Unplug the cord and remove the blade.
- Lower the blade fully and lock adjustments (if possible).
- Remove loose accessories (fence, miter gauge, throat plate) and bundle them.
- Wrap sharp items (blades, dado sets) in heavy cardboard and tape the edges.
- Bag small hardware so it does not spill during transport.
| Condition of the saw | What we recommend | Why |
|---|---|---|
| Runs, cuts straight, complete | Sell or donate | Keeps a usable power tool in service |
| Runs but missing parts | Give away or sell as-is | Someone can rebuild it with parts |
| Does not run, damaged, unsafe | Scrap metal recycling | Safest end-of-life option |
Table saws are heavy and have exposed sharp components. Handling the blade and cord correctly reduces the risk of cuts, punctures, and accidental start-up while you are moving or disposing of the saw.

What are the common table saw mistakes?
Common table saw mistakes on the Craftsman 11327580 (8-inch tilting arbor bench saw) include skipping basic safety steps, using the wrong cutting setup, and forcing stock through the blade. These errors increase kickback risk, reduce cut accuracy, and can damage the blade, fence, or arbor.
- Not wearing proper PPE (eye protection and hearing protection)
- Cutting without a splitter or riving knife when the saw is designed to use one
- Standing directly behind the workpiece (puts you in the kickback line)
- Using the rip fence and miter gauge together for the same cut (can pinch the work)
- Using a dull, dirty, or incorrect blade for the material
- Setting the blade too high above the workpiece
- Cutting freehand instead of using the fence or miter gauge
- Not using push sticks or push blocks for narrow rips
Use this short checklist to reduce binding and kickback:
- Confirm the blade is sharp, clean, and tightened
- Verify the fence is parallel to the blade
- Make sure the miter gauge is used for crosscuts and the fence is used for rips
- Support long boards with outfeed support so the cut stays flat
- Keep the tabletop clear so offcuts cannot contact the spinning blade
| Item | Good practice | What goes wrong if ignored |
|---|---|---|
| Blade height | Keep blade just high enough to clear the stock | Higher blade exposure increases severity of contact and can worsen tear-out |
| Feed rate | Steady, controlled feed | Forcing the cut can stall the motor and increase burning or kickback |
| Hand position | Use push tools for narrow stock | Hands drift too close to the blade |
Most table saw incidents start with binding or loss of control. A correct cutting method (right guide, sharp blade, proper stance, and push tools) keeps the workpiece moving predictably and helps protect the saw’s arbor, bearings, and alignment.
