Craftsman 135276102 7-1/4" industrial worm drive saw Parts

For your Craftsman model 135276102 (7-1/4" industrial worm drive saw), the blade size is determined by the blade’s diameter and arbor (center hole) size. The fastest way is to read the blade’s etched markings; if they’re worn off, measure the blade diameter and arbor hole directly.

• Read the blade etching/printing: look for diameter (for example, 7-1/4"), arbor size (commonly 5/8"), and tooth count.
• Measure the diameter: measure straight across the blade through the center (tip to tip).
• Measure the arbor hole: use a ruler or calipers across the center hole.
• Check the saw’s blade guard label: many saws list max blade diameter and arbor size near the guard.
• Match the blade to the application: framing blades often have fewer teeth; finish blades have more.

Using the correct diameter and arbor size helps the blade seat properly, keeps the guard working as designed, and prevents poor cuts, binding, and excessive vibration.

Framers often choose a worm drive saw like the Craftsman 135276102 because it delivers high torque for ripping and crosscutting dense framing lumber, keeps the motor weight behind the blade for steady tracking, and commonly uses a blade-left layout that makes the cut line easier to see for right-handed users.

A worm gear drive trades blade speed for pulling power, which is why it feels strong in demanding cuts.

• Higher torque for long rips in 2x material and sheet goods
• Better control when the saw is loaded down (less “bogging”)
• Stable feel because the motor sits inline with the cut
• Often preferred for roof framing and repetitive production cuts
• Built for jobsite durability and long duty cycles

Worm drives are popular, but they are not “better at everything.”

• Extra weight: Use a stable stance and support long stock to reduce fatigue.
• More maintenance: Many worm drives use gear oil; check and maintain it on schedule.
• Different balance: Let the saw’s weight do the work; avoid forcing the feed rate.

On a framing crew, time and consistency matter. A worm drive’s torque and tracking help keep cuts straight and repeatable in wet, dense, or pressure-treated lumber, which reduces re-cuts and helps the saw hold up under daily jobsite use.

Most Craftsman 10-inch table saws use a 5/8-inch arbor, but your Craftsman model 135276102 is a 7-1/4-inch industrial worm drive saw (not a table saw), so arbor size depends on the blade and arbor hardware used on this specific saw.

We recommend confirming arbor size by checking the blade you are using and measuring the arbor shaft diameter (or the blade’s center hole).

• Unplug the saw and remove the blade guard as needed for access
• Remove the blade and look for the arbor hole size stamped on the blade (common sizes are 5/8 inch and 20 mm)
• Measure the arbor shaft with a caliper or a wrench set (shaft diameter equals arbor size)
• Check for any adapter ring/bushing installed in the blade’s center hole
• Reinstall the blade and tighten the arbor nut securely (do not overtighten)

Using the wrong arbor size (or the wrong bushing) can cause blade wobble, poor cut quality, vibration, and unsafe operation. Matching the blade’s arbor hole to the saw’s arbor shaft keeps the blade centered and clamped correctly.

Yes. A 6-1/2 inch circular saw can cut a 2x4 in a single pass in most situations because a 2x4 is about 1-1/2 inches thick; that is well within the typical cutting depth of this blade size. For your Craftsman 135276102 (7-1/4 inch industrial worm drive saw), cutting 2x4s is a standard task.

• Confirm the blade is rated for the saw’s RPM and is installed in the correct direction.
• Use a sharp framing or general-purpose blade for construction lumber.
• Set blade depth so the teeth extend about 1/4 inch below the board.
• Support the 2x4 so the cutoff can drop freely without pinching the blade.
• Keep the cord (or battery, if applicable) clear of the cut line.

These are common, real-world ranges for circular saws; exact depth varies by brand and design.

• Blade is dull or the wrong tooth count (too fine for framing lumber).
• Depth is set too shallow.
• The board is bowed, twisted, or pinching the kerf.
• You are feeding too fast, causing the motor to bog down.

Using the right blade depth and support reduces kickback risk, improves cut quality, and helps protect key wear items like the blade, arbor area, and guards on your Craftsman worm drive saw.

A 10-inch Craftsman table saw is typically labeled by electrical rating (amps/volts) rather than motor “size” in horsepower. The model on this page, Craftsman 135276102, is a 7-1/4-inch industrial worm drive saw, so its motor specs are different from a 10-inch table saw.

Most portable/jobsite 10-inch table saws use a universal (brush-type) motor and are commonly listed like this:

• 120V corded power
• 15-amp circuit rating
• No-load blade speed often around 4,500 to 5,000 RPM
• Universal motor (not an induction motor)
• “Peak HP” may be advertised, but amps is the spec used for parts and electrical matching

The most accurate answer comes from the saw’s data plate (nameplate), not the blade size.

• Unplug the saw before checking
• Find the nameplate on the frame, motor housing, or under the table
• Record volts (V), amps (A), watts (W), and RPM if shown
• Use that information when selecting a switch, cord, brush set, or breaker/extension cord

Motor ratings determine which electrical parts fit and how the tool should be powered. Using a table saw motor rating when you actually have a worm drive saw (or vice versa) leads to incorrect parts selection and nuisance breaker trips.
