Craftsman 319190620 bench grinder Parts

A Craftsman bench grinder (including model 319190620) is a stationary power tool that spins abrasive wheels to grind, sharpen, shape, and clean up metal. We typically use it for sharpening hand tools, deburring cut edges, and removing rust or paint from small parts.

• Sharpen chisels, plane irons, mower blades, and drill bits (with the right technique)
• Grind and shape metal (bolts, brackets, tool edges)
• Deburr freshly cut metal to remove sharp edges
• Clean metal using a wire wheel or wire cup attachment (if your grinder supports it)
• Polish with a buffing wheel (light-duty finishing)

• Unplug the grinder before adjusting tool rests, guards, or wheels.
• Verify the wheel is rated for the grinder’s RPM before installing it.
• Keep tool rests close to the wheel (a small gap) to prevent the workpiece from catching.
• Let the wheel reach full speed before grinding; use light pressure.
• Wear eye protection and avoid loose sleeves or gloves near rotating wheels.

A bench grinder removes material fast; the right wheel, guard setup, and technique help you get cleaner results (sharper edges, smoother deburring) while reducing vibration, overheating, and kickback.

Four important bench grinder rules for your Craftsman 319190620 are: wear proper eye and face protection, keep the work rest and guards correctly adjusted, grind only on the wheel’s face (not the side), and always start and stop safely (let it reach full speed; wait for a complete stop before handling the work).

• Protect yourself: Wear safety glasses plus a face shield; tie back hair and avoid loose sleeves or gloves that can catch.
• Set the grinder up correctly: Keep guards in place and adjust the work rest close to the wheel (typically about 1/8 inch) so small parts cannot wedge.
• Use the wheel correctly: Grind on the front face of the wheel only; side pressure can crack many bench grinding wheels.
• Start and stop safely: Stand slightly to one side at startup, let the wheel reach full speed before grinding, and wait until the wheel fully stops before setting tools down near it.

These are common bench grinder safety targets used across many Craftsman-style grinders.

Most bench grinder injuries come from wheel breakage, flying grit, or a workpiece getting grabbed between the wheel and rest. Following these four rules reduces kickback, binding, and exposure to sparks and fragments.

If your grinder vibrates, won’t start, or trips a breaker, electrical checks are often part of safe diagnosis. Use our guide: how to use a multimeter to test electrical parts video.

A Craftsman bench grinder like model 319190620 typically weighs about 15 to 35 lb depending on wheel size, motor housing, and base style. For the exact weight of your specific unit, match the model number on the tool to the listing details you use when ordering parts on Sears PartsDirect.

Most bench grinders fall into these practical ranges:

• 6-inch bench grinder: about 15 to 25 lb
• 8-inch bench grinder: about 25 to 40 lb
• Industrial/heavy-duty units: 40 lb and up

These features usually make one grinder heavier than another:

• Wheel diameter and thickness (larger wheels add mass)
• Motor size and frame material (more metal, more weight)
• Cast-iron base vs. stamped steel base
• Built-in work lights, guards, and tool rests
• Pedestal mounting hardware (if included with your setup)

Weight affects stability and vibration. A heavier bench grinder generally stays planted better during sharpening and grinding, which helps you get cleaner results and reduces the chance of the tool “walking” on the bench.

• Set the grinder on a solid, level workbench.
• Bolt it down if you notice vibration.
• Keep wheel guards installed and properly adjusted.
• Replace wheels that are chipped, cracked, or out of round.
• If you are troubleshooting power issues, use a meter safely; see how to use a multimeter to test electrical parts video.

A 5/8-11 arbor means the grinder’s spindle (arbor) has a 5/8-inch diameter with 11 threads per inch. On many U.S. grinders, that thread size is a common standard for mounting compatible accessories, but you still need to match the accessory type and rated speed.

• 5/8: the outside diameter of the threaded arbor (in inches)
• 11: threads per inch (TPI)
• Right-hand thread is most common (tightens clockwise), but always confirm on your tool
• “Arbor” and “spindle” are often used interchangeably

For your Craftsman 319190620 bench grinder, arbor size is only one fit requirement. Also check:

• Wheel type (bench grinding wheel vs. wire wheel vs. buffing wheel)
• Wheel diameter and thickness (must clear guards and tool rests)
• Maximum RPM rating on the wheel (must be at least the grinder’s no-load speed)
• Bushing/adapters included with the wheel (common on bench grinder wheels)
• Flanges and washers condition (bent or missing hardware causes wobble)

If the arbor thread does not match, the wheel or attachment will not seat correctly and can loosen, wobble, or bind. Matching arbor size plus wheel rating and hardware fit helps your bench grinder run smoother and safer.

To restore your Craftsman bench grinder model 319190620, do a full clean, inspection, and tune-up first; then repair wiring and replace any worn rotating parts. A proper restoration reduces vibration, improves wheel tracking, and keeps the grinder safe to use.

• Unplug the grinder before any work.
• Wear eye protection and a dust mask when removing rust, paint, or wheel debris.
• Never run without guards, tool rests, and eye shields installed.
• Replace any wheel that is cracked, chipped, or has been dropped.
• Fix brittle or cracked wire insulation before powering on.

• Document and label: Take photos of spacers, flanges, guards, and wire routing.
• Disassemble and degrease: Remove guards, tool rests, wheels, and covers; clean thoroughly.
• Inspect bearings and shaft: Spin by hand; roughness, play, or noise means bearing service.
• Inspect switch and cord: Look for loose terminals, heat discoloration, or damaged insulation.
• Remove rust and refinish: Wire brush or sand; prime and paint if desired.
• Reassemble and align: Set tool rest close to the wheel and square to the face.
• Dress the wheels: Dress after mounting so the wheel runs flat and true.

Use a multimeter to verify the grinder is safe to energize:

• Confirm cord continuity and no shorts to the metal frame
• Test the switch for consistent on/off continuity
• Repair damaged conductors and secure strain relief

A bench grinder runs at high speed; worn bearings, damaged wheels, or compromised wiring create vibration and unsafe operation. Restoring the grinder correctly gives smoother grinding and safer starts.
