Craftsman 31517360 router Parts

To replace a router bit on your Craftsman 31517360 router, unplug the tool, loosen the collet nut, remove the old bit, then insert the new bit and tighten the collet securely. A properly seated bit prevents slipping, chatter, and poor cut quality.

Steps to change the bit (collet-style router)

• Unplug the router (never change bits with power connected).
• Remove the base if needed for better access to the collet and nut.
• Press the spindle lock (if equipped) or hold the shaft with the correct wrench.
• Turn the collet nut counterclockwise until the bit releases.
• Pull the old bit out; clean dust from the collet and nut.
• Insert the new bit shank fully, then pull it back out about 1/16 to 1/8 inch.
• Tighten the collet nut firmly (snug plus a solid final tighten, not over-tightened).

Correct bit fit and depth (quick guide)

What to check	What “right” looks like	Why it matters
Shank size	Matches the collet (commonly 1/4 inch or 1/2 inch)	Wrong size can slip or damage the collet
Insertion depth	Not bottomed out; backed off slightly	Helps the collet clamp evenly
Shank condition	Clean, smooth, not scored	Improves grip and reduces runout
Tightness	Firmly tightened with the proper wrench	Prevents bit creep during a cut

If the bit is stuck in the collet

• Loosen the collet nut a few turns (do not remove it).
• Tap the wrench lightly to break the taper grip.
• If your router uses a self-releasing collet, keep loosening until you feel it “pop” free.
• Wipe the bit shank and inside of the collet; resin buildup can make bits stick.

Why it matters

A router bit that is inserted too shallow, bottomed out, or not tightened correctly can slip under load. That leads to burning, rough edges, and unsafe handling, especially with larger straight bits, round-over bits, or flush-trim bits.

A Sears Craftsman router (like model 31517360) is a handheld or table-mounted power tool used to shape, trim, and cut wood with a spinning router bit. We commonly see it used for edge profiles, dadoes, rabbets, and hinge mortises; you can find model-specific replacement parts through Sears PartsDirect.

What a router does (and why woodworkers use it)

A router’s motor spins a bit at high speed so you can remove material cleanly and consistently. With the right bit and setup, a Craftsman router can handle both rough shaping and finish-quality detail work.

• Shapes edges (roundovers, chamfers, ogees)
• Cuts grooves and slots (dadoes, rabbets)
• Flush-trims laminate or wood to a template
• Cuts joinery (mortises, some dovetail/jig work)
• Makes repeatable cuts with guides, fences, or templates

Common parts and accessories you may need

Even without a model-specific parts list shown here, these are the items we most often see customers replace or shop for on a corded Craftsman router:

• Collet and collet nut (grips the bit shank)
• Brushes (wear item on many universal motors)
• Switch or power cord (if the tool is intermittent)
• Base components (fixed base or plunge base parts)
• Depth adjustment hardware (stop rod, turret, lock lever)

Quick safety and setup checks

Unplug the router before changing bits or inspecting parts.

Task	What to check	Why it matters
Install a bit	Fully seat, then back off slightly before tightening	Helps prevent bit slip and collet binding
Choose speed	Match speed to bit size (larger bits run slower)	Reduces burning and kickback risk
Secure the work	Clamp the workpiece and stabilize the base	Improves cut quality and control
Direction of cut	Feed against bit rotation	Helps prevent the router from “running away”

Why it matters

Knowing what a Craftsman router is and how it’s used helps you pick the right replacement parts (like a collet or switch) and troubleshoot issues such as poor cut quality, burning, chatter, or loss of power.

For a Craftsman router like model 31517360, the bit shank size must match the collet installed in the router. Many Craftsman routers use a 1/4-inch collet, and some accept 1/2-inch with the correct collet; confirm yours by checking the collet.

How to confirm the shank size on Craftsman 31517360

Always match the bit shank diameter to the collet opening exactly.

• Unplug the router before inspecting the collet or changing bits
• Remove the collet nut, then slide the collet out (if it is removable)
• Measure the inside diameter of the collet opening with a ruler or caliper
• Use only bits with the same shank size as the collet (no makeshift sleeves)
• Insert the bit shank fully, then pull it back slightly (about 1/16 inch) before tightening

Common router bit shank sizes

These are the sizes you will typically see for handheld and bench routers.

Shank size	What it fits	Typical use
1/4 inch	1/4-inch collet	Trim work, edge profiles, lighter cuts
1/2 inch	1/2-inch collet	Larger bits, deeper cuts, less vibration

Why it matters

A router bit that does not match the collet can slip, chatter, or vibrate. Correct collet-to-shank fit helps the collet clamp evenly, improves cut quality, and reduces the risk of the bit coming loose.

Getting the right parts and info

If you need a replacement collet, collet nut, or other parts for Craftsman 31517360, search by your full model number on Sears PartsDirect. For help confirming the model number from the tool’s label, use how to find your appliance model number (and what it means for parts).

Yes. Craftsman has sold router tables and router table accessories; for your Craftsman router model 31517360, the right table is the one that matches your router’s base mounting pattern or works with a universal insert plate. You can also search additional options by model on Sears PartsDirect.

How to choose a router table that fits a 31517360 router

Focus on fit and safe mounting rather than brand name alone.

• Check whether the table supports direct-mounting to the router base or requires an insert plate
• Confirm the table (or plate) includes a drilling template or pre-drilled patterns that match common router bases
• Make sure you can reach the height adjustment and power switch when the router is mounted upside down
• Verify the table opening supports your bit changes (some setups require removing the router)
• Choose a fence that can accept dust collection and stays square under load

Common mounting options (what they mean)

Option	What it requires	Why customers pick it
Direct mount	Table holes match your router base	Simplest setup when it lines up
Universal insert plate	Plate matches your router, plate drops into table	Easiest way to fit many routers
Lift-ready setup	Compatible plate and lift system	Fast, precise height changes

Why it matters

A router table only works well when the router mounts flat and rigid. A poor match causes vibration, off-center bits, and inconsistent depth, which affects cut quality and control.

Quick safety checks before first use

• Unplug the router before mounting, adjusting, or changing bits
• Confirm the router is bolted tight and the bit is centered in the opening
• Use the correct collet and fully seat the bit shank (then back it out slightly before tightening)
• Keep the cord and switch accessible and away from moving parts
