Craftsman 137221940 table saw Parts

The Craftsman 137221940 table saw uses a 10-inch blade. This is the standard blade diameter specified for this model, and it determines what replacement blades (and compatible accessories) will fit and run safely; see the 137221940 owner's manual for details.

How to confirm you are buying the right blade

Use these quick checks before ordering a new table saw blade:

• Match the blade diameter: 10 inches
• Match the arbor (center hole) size to your current blade (most 10-inch saw blades are 5/8 inch, but confirm)
• Choose the right tooth count for the cut (rip vs. crosscut vs. combination)
• Verify the blade is rated for at least the saw’s speed (this model is listed at 5000 RPM)
• Inspect the blade guard and splitter alignment after installing a new blade

Common blade and accessory fit notes for this model

The manual also lists a dado limitation that matters when you are shopping for cutting accessories.

Item	What fits this saw	What to avoid
Standard saw blade	10-inch blade	Wrong diameter blades
Dado set	Up to 6-inch diameter, max 1/2-inch dado width	Adjustable (wobble) dadoes; dado sets larger than 6 inches

Why it matters

Using the correct blade size helps the blade guard, splitter, and rip fence work as intended. A mismatched blade can cause poor cut quality (burning, wandering cuts) and can interfere with height or bevel adjustments.

Yes. Craftsman table saws are a solid choice for many DIYers, and the Craftsman 137221940 is built as a practical, high-speed 10-inch saw (rated up to 5000 RPM) that handles common ripping and crosscutting tasks well when it is assembled, aligned, and used with the proper safety accessories listed in the owner's manual.

What “good” means for the Craftsman 137221940

A “good” table saw is one that stays accurate, cuts consistently, and is safe to operate. For this model, the manual highlights key basics that support that goal:

• 10-inch blade capacity (common size for general woodworking)
• Up to 5000 RPM for clean cuts when the blade is sharp
• Designed to be used with a rip fence or miter gauge (not freehand)
• Includes safety components like blade guard, splitter/spreader, and anti-kickback pawls
• Intended for typical home-shop use when maintained and kept aligned

How to get the best results (and avoid the common complaints)

Most “mixed reviews” on table saws come down to setup, alignment, and technique. These steps make the biggest difference:

• Wax the table surface to reduce friction so stock feeds smoothly
• Confirm the rip fence locks parallel to the blade (reduces burning and kickback risk)
• Use the miter gauge for crosscuts and the fence for ripping; never guide stock by hand alone
• Use a push stick for narrow rips
• Keep the blade clean and sharp; a dull blade makes any saw feel underpowered

If your cuts are not square or angles drift, use our guide on table saw bad angle cuts.

Quick comparison: who it fits best

User type	Fit for 137221940	Why
DIYer / homeowner	Good	10-inch blade, strong speed, practical features
Hobby woodworker	Good	Capable for repeatable cuts with careful alignment
Jobsite daily pro	Fair	Pros often demand faster adjustments and tighter tolerances

Why it matters

A table saw can only be “good” if it is safe and predictable. Using the blade guard/spreader and anti-kickback pawls when possible, keeping hands out of the blade line, and avoiding freehand cuts are the difference between confident results and frustrating, risky cutting.

The most common mistakes on a Craftsman table saw like model 137221940 are skipping basic safety steps (eye protection, blade guard, push stick), making freehand cuts, and standing in line with the blade. These errors increase kickback risk and blade-contact injuries; our 137221940 owner's manual spells out the safe setup and cutting rules.

Common mistakes we see (and what to do instead)

• Not wearing eye protection: Always wear safety goggles (ANSI-rated) before powering on.
• Running without the blade guard/spreader and anti-kickback pawls: Use them for operations where they apply, including through-sawing.
• Cutting freehand: Always guide the work with the rip fence or miter gauge.
• Standing directly behind the cut line: Keep your body out of the blade path to reduce injury risk if kickback happens.
• Using hands too close to the blade: Use a push stick for narrow ripping and keep hands out of the blade line.
• Leaving the saw unattended: Turn the switch OFF and wait for a complete stop before walking away.

Quick pre-cut safety checklist (model 137221940)

Before each use, we follow the same basics:

• Blade is tight on the arbor
• Bevel angle lock knob is tight
• Rip fence is locked and parallel to the miter gauge grooves (when ripping)
• Blade guard is installed and working properly
• Safety glasses are on

Task	Safer setup	Common mistake
Ripping	Fence locked; use push stick when needed	Freehand ripping or reaching near blade
Crosscutting	Remove rip fence; use miter gauge in the groove	Using fence and miter gauge together (pinch risk)
Blade height	Set blade about 1/8 inch above the workpiece	Blade set too high

Why it matters

Most table saw injuries happen fast, and the manual warns that even a fraction of a second of carelessness can cause severe injury. Using the guard system, correct guides (fence or miter gauge), and proper stance reduces kickback and keeps your hands out of the blade path.

Yes, you can use an 8-inch blade on the Craftsman 137221940 table saw as long as the blade has the correct arbor (shaft) hole size and is rated for the saw’s speed; the tradeoff is reduced maximum cutting depth compared with a 10-inch blade. For dado work on this model, our manual specifies using a 6-inch dado set.

What changes when you drop from 10-inch to 8-inch

Using a smaller diameter blade is usually about clearance and cut capacity, not “fit.” Expect these differences:

• Shallower cut depth (an 8-inch blade cuts less deep than a 10-inch blade)
• Potentially less strain in some cuts (less blade mass), but feed rate still matters
• Guard and splitter alignment may not match the smaller blade height
• Riving knife/splitter and anti-kickback setup still needs to be correct for safe ripping

Fit and safety checks we recommend

Before installing any non-original blade size, verify these basics:

• Arbor hole size matches your saw’s arbor (do not force-fit)
• Blade RPM rating meets or exceeds the saw’s operating speed (this model is listed at 5000 RPM)
• Blade clears the throat plate and housing through full height and bevel travel
• Blade is tightened on the arbor before every use
• Fence is parallel to the miter gauge grooves to reduce binding and kickback risk

Dado note for Craftsman 137221940

This model includes a dado table insert, but the manual limits dado setup as follows:

Setup item	What to use on this model	Why it matters
Dado diameter	6-inch dado set	Helps ensure internal clearance and proper operation
Max dado width	1/2 inch	Arbor length restricts stack width
Guard/splitter	Removed for dado cuts	Required for dado operation; use extra caution

For the exact blade-change steps and dado instructions, use the 137221940 owner's manual.

Why it matters

Blade diameter affects cutting depth, guarding geometry, and clearance inside the saw. Matching the arbor fit and RPM rating keeps the blade stable at speed, and following the model’s dado limits helps prevent contact with the housing or insert.

No, table saw miter gauges are not universal. Your Craftsman table saw model 137221940 uses a miter gauge that rides in the table’s miter slot, and compatibility depends on the slot size and the gauge’s bar dimensions and adjusters. For safe operation, use a miter gauge that fits the slot without side-to-side play.

What makes a miter gauge “compatible”

A miter gauge has to match the saw’s miter slot and lock securely at the angle you set. Before buying a replacement or upgrade, we check these items:

• Miter slot size and shape (common sizes are 3/4 inch by 3/8 inch, but not all saws match)
• Bar fit: slides smoothly but has minimal wiggle
• Angle stops and lock: holds 90° and common angles without drifting
• Right-slot use: this saw’s manual calls out using the right side groove for crosscutting and compound miter cuts
• Fence clearance: the gauge and workpiece must clear the blade guard and splitter when installed

For model-specific setup and safe crosscutting steps, use the 137221940 owner's manual.

Quick fit check before you purchase

Use this simple checklist to avoid a poor fit that causes inaccurate cuts:

• Measure the slot width and depth with a ruler or calipers
• Confirm the gauge bar is the same size (or has expansion discs/adjusters to remove play)
• Slide it end-to-end; it should not bind or rock
• Lock the head at 90° and verify it stays square during a test cut
• Tighten the miter lock knob fully; a loose lock is a common cause of inaccurate crosscuts

Why it matters (accuracy and safety)

A loose or mismatched miter gauge can twist during the cut, leading to bad angles, burning, or kickback risk. The manual also stresses holding the work firmly against the miter gauge or rip fence and avoiding “free hand” cutting.

Common symptoms and likely causes

Symptom	What it usually points to
Crosscuts not square at 90°	Miter gauge out of adjustment, lock not tight
Angles drift during a cut	Poor bar fit in slot, worn lock mechanism
Rough, inconsistent feed	Table pitch buildup, alignment issues

If your angles are off even with a good-fitting gauge, follow the alignment guidance in table saw bad angle cuts.
