Craftsman 31517431 router Parts

To remove a router bit from your Craftsman router model 31517431, unplug the tool, lock the spindle (or hold it with a wrench), then loosen the collet nut until the bit releases and slides out. If the bit feels stuck, a second loosen step usually frees it.

Step-by-step: removing the bit safely

• Unplug the router (do not rely on the switch).
• Remove the base if it blocks access to the collet and bit.
• Press and hold the spindle lock (if your router has one). If it does not, use two wrenches.
• Turn the collet nut counterclockwise to loosen.
• Keep loosening until you feel the bit “pop” free from the collet taper.
• Slide the bit straight out; wipe the shank clean before reinstalling.

What to do if the bit is stuck

A bit can bind in the collet from pitch buildup, overtightening, or a slightly undersized shank.

• Loosen the collet nut a few turns, then loosen a bit more until the collet releases.
• Tap the wrench handle lightly (controlled, not hard) to help break the collet’s grip.
• Remove the bit and clean the collet and bit shank with a dry rag.
• If you see resin buildup, clean and dry thoroughly before reassembly.

Quick reference: common router collet setups

Setup	What you use	What you’ll notice
Spindle lock style	1 wrench	Button/lock holds the shaft while you loosen
Two-wrench style	2 wrenches	One holds the shaft, one turns the collet nut

Why it matters

A properly released collet prevents damage to the collet, nut, and bit shank. It also helps the bit seat correctly next time, reducing vibration and improving cut quality.

Yes. Craftsman has made router tables and router-table accessories that can be used with many Craftsman routers, including models in the same family as the Craftsman 31517431. The key is matching the router’s base mounting pattern, bit clearance, and intended use (handheld vs. table-mounted).

How to confirm a router table will work with your 31517431

A router table is only a good fit if the router can mount securely and operate safely. Before buying or setting up a table, we recommend checking:

• Mounting compatibility: the table’s insert plate must match (or be drillable for) your router’s base screw pattern
• Base opening size: enough clearance for the largest bit you plan to use
• Depth adjustment access: whether you can adjust bit height from above the table (or at least easily from below)
• Switching: a safe way to turn the router on and off (many tables use a separate safety switch)
• Dust collection: a fence port and/or cabinet port to control chips

Router table types (what most DIYers choose)

Router table type	Best for	What to watch for
Benchtop router table	Small shops, occasional use	Lighter fences can flex; smaller work surface
Cabinet-style router table	Frequent use, better dust control	Heavier, takes more space
Table saw wing router table	Saving space	Fence alignment and shared workspace

Why it matters

A router table turns your Craftsman 31517431 into a more controlled setup for edge profiles, grooves, and repeatable cuts. The wrong table or insert plate fit can cause vibration, poor cut quality, or unsafe operation.

A Sears Craftsman router, like the Craftsman 31517431, is a handheld power tool used to shape, trim, and cut wood with a spinning router bit. We commonly see it used for edge profiles, dadoes, rabbets, hinge mortises, and laminate trimming.

What it’s used for

A router is designed to remove material accurately and repeatedly. Typical woodworking tasks include:

• Rounding over or chamfering edges with profile bits
• Cutting grooves (dadoes) and slots
• Cutting rabbets for cabinet backs
• Flush-trimming laminate or wood to a template
• Making mortises for hinges or hardware

Key features you’ll typically see on a Craftsman router

Exact specs vary by version and accessory setup, but most corded Craftsman routers in this class share common elements:

• 120V corded electric motor (standard U.S. household power)
• Adjustable depth setting (depth stop or ring adjustment)
• Collet to hold common shank sizes (often 1/4-inch and sometimes 1/2-inch)
• Base that can be used freehand or with guides
• Compatibility with edge guides, template guides, and straight bits

Quick comparison: router vs. other common tools

Tool	Best for	Typical result
Router	Shaping and precise joinery cuts	Clean profiles, grooves, flush trims
Jigsaw	Curved cuts in sheet goods	Rougher edge, needs sanding
Circular saw	Straight cuts in lumber/sheet goods	Fast rip/crosscuts
Trim router	Light edge work and laminate	Smaller cuts, easier one-hand control

Why it matters

Knowing what a router does helps you pick the right bit, depth setting, and guide method for safer, cleaner cuts. It also helps when you are troubleshooting issues like burning, chatter, or tear-out, which are usually tied to bit choice, speed, and feed rate.

Yes. Craftsman makes corded routers, and your Craftsman router model 31517431 is a corded-style woodworking tool that runs from a standard power cord for steady power during routing, edge profiling, and dado work.

What “corded router” means (and why people choose it)

A corded router plugs into an outlet, so you get consistent RPM and torque for longer cuts without stopping to recharge.

• Steadier power for heavy cuts in hardwood
• No battery downtime; good for long sessions
• Typically higher sustained RPM under load
• Works well with router tables and jigs
• Easy to pair with a shop vacuum for dust control

Quick comparison: corded vs cordless routers

Feature	Corded router	Cordless router
Runtime	Unlimited (plug-in)	Limited by battery
Best for	Router table, long cuts, larger bits	Quick trim work, portability
Power consistency	High	Varies with battery level
Typical use	Shop projects, repeated passes	On-site, light-duty tasks

How to confirm what you have on model 31517431

Use these checks to identify corded configuration and match the right replacement items (like a cord, switch, or brushes) when servicing.

• Look for a fixed power cord exiting the motor housing
• Check the rating label for amps (A) and volts (V)
• Inspect the cord strain relief for cracking or looseness
• If the router cuts out, check the cord for internal breaks near the handle
• If the motor runs rough or sparks heavily, inspect the brushes and commutator

Why it matters

Corded routers like the Craftsman 31517431 are a strong choice when you need repeatable performance for woodworking projects. Knowing it is corded helps you troubleshoot common issues (power loss, worn brushes, switch problems) and choose compatible repair parts.
