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.

What you can do with a bench grinder

• 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)

Key parts and features (what they do)

Feature	What it does	Why it matters
Grinding wheels	Remove material and shape edges	Wheel grit controls speed vs. finish quality
Tool rests	Support the workpiece at a stable angle	Helps keep sharpening consistent and safer
Eye shields/spark guards	Deflect debris and sparks	Reduces risk of eye and face injury
Wheel guards	Contain fragments if a wheel fails	Critical for safe operation

Basic safety and setup checks we recommend

• 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.

Why it matters

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).

The 4 rules (with what to do)

• 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.

Quick setup targets (typical)

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

Item to adjust	Typical target	Why it matters
Work rest gap	~1/8 inch	Prevents the workpiece from being pulled into the wheel
Tongue guard (spark guard) gap	~1/4 inch	Helps contain debris and reduces pinch points
Startup position	Off to the side	Reduces risk if a wheel fails at startup

Why it matters

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.

Helpful DIY skill for safe troubleshooting

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.

Typical bench grinder weight ranges

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

Grinder type	Common wheel size	Typical weight
Light-duty bench grinder	6 in.	15 to 25 lb
Medium-duty bench grinder	8 in.	25 to 40 lb
Heavy-duty grinder/buffer	8 to 10 in.	40 lb+

What changes the weight the most

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)

Why it matters

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.

Quick handling and setup tips

• 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.

What the numbers mean

• 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

How to use this when buying wheels or accessories

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)

Quick compatibility checklist

Item to match	What to look for	Why it matters
Arbor thread	5/8-11	Ensures the accessory can screw on correctly
RPM rating	Wheel RPM ≥ grinder RPM	Prevents wheel failure
Wheel style	Rated for grinding	Wrong style can load up or break
Hardware	Correct flanges, tight nut	Reduces vibration and runout

Why it matters

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.

Safety first

• 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.

Restoration checklist (practical order)

• 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.

Electrical checks (quick and important)

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

Common “restore vs replace” calls

Symptom	Likely cause	Best next step
Loud rumble	Worn bearings	Replace bearings before use
Heavy vibration	Wheel/flange issue or bearings	Replace wheel, inspect flanges, check bearings
Slow start, overheating	Electrical resistance or motor issue	Inspect cord, switch, and motor

Why it matters

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.
