How to replace router bits sears Craftsman router?
To replace a bit on your Craftsman router model 32017543, unplug the router, lock the spindle, loosen the collet nut, remove the old bit, then insert and tighten the new bit correctly. Follow the safety limits for bit diameter and cutting depth in the owner's manual.
- Turn the motor OFF and unplug the router.
- Remove the motor from the fixed base or plunge base (if your kit uses separate bases).
- Set the motor upside down on its top cap with the collet/nut pointing up.
- Press the spindle lock button to lock the spindle shaft.
- Use the wrench to turn the collet nut counterclockwise to loosen it.
- Pull the bit shank out; insert the new bit shank, then tighten the collet nut firmly.
The sub-base opening on this router is 1-1/4 inch. Using a cutter bit larger than the opening can damage the sub-base and create a serious loss-of-control hazard.
| What you are doing | What to check | What to do |
|---|---|---|
| Installing a larger-diameter bit | Bit must fit through the sub-base opening | Use a larger-opening sub-base (sold separately) |
| Using bits over 1-1/2 inch diameter | Router speed setting | Set the speed dial to 1 or 2 |
| Making a deep cut | Depth per pass | Remove no more than 1/8 inch per pass |
- Keep the bit shank, collet/nut, and spindle clean and free of dust, chips, grease, and rust.
- The collet/nut is self-releasing; do not strike it to free a bit.
- If a bit feels stuck after use, loosen the collet nut a little more until it releases.
- If the spindle looks dry, apply a small amount of machine oil.
A properly seated bit and a clean collet help prevent bit slippage, chatter, burning, and kickback. Staying within the 32017543 sub-base opening and speed limits also reduces the risk of losing control during routing.

Can you turn a fixed base router into a plunge router?
Yes, you can convert a fixed base router into a plunge-style setup if your Craftsman router system supports an approved plunge base for the motor. For the Craftsman 32017543, the key requirement is that the motor must be installed in an approved fixed or plunge base and clamped securely before use (see the owner's manual).
Most of the time, you are not modifying the motor itself. You are:
- Moving the same motor housing into a plunge base (if your kit includes one)
- Using plunge action to start internal cuts (grooves, mortises, inlays)
- Locking the plunge mechanism when you need a fixed depth
If your router only has a fixed base and no compatible plunge base, a true conversion requires a purpose-built plunge base that matches the motor housing and clamp design.
A plunge base has to hold the motor rigidly and control depth accurately. Before routing:
- Unplug the router before adjustments, bit changes, or base changes.
- Install the motor only in an approved fixed or plunge base (never run the motor “free”).
- Clamp the motor so it cannot move up or down in the base.
- Keep a firm two-hand grip to control starting torque.
- Clamp the workpiece securely; do not try to hold it by hand.
| Task | Fixed base | Plunge base |
|---|---|---|
| Edge profiling (roundover, chamfer) | Best choice | Works, but not required |
| Dados and grooves starting in the middle | Harder (often requires careful entry) | Best choice |
| Mortises and inlays | Limited | Best choice |
| Repeatable depth setting | Very good | Very good (when plunge is locked) |
Plunge routing is mainly about control and safer “start the cut” technique for internal routing. If the motor is not clamped securely in the base, depth settings shift and the tool can become unstable, which increases the risk of losing control.

What size shank is a Craftsman router?
For the Craftsman router model 32017543, we use both 1/4-inch and 1/2-inch shank router bits because this router comes with 1/4-inch and 1/2-inch collets/nuts. Confirm the bit and collet match before tightening the collet nut; details are in the 32017543 owner's manual.
Use the shank size that matches the collet installed in your router.
- 1/4-inch shank: common for lighter profiling, smaller bits, and tighter detail work
- 1/2-inch shank: preferred for larger bits and heavier cuts because it’s typically more rigid
- Never force a bit into the wrong collet; swap to the correct collet/nut set first
- Insert the bit shank fully, then back it out slightly before tightening (helps prevent bottoming out)
If you are unsure what’s currently installed, measure the opening of the collet (or the bit shank) with a ruler or calipers.
| What you have | What it fits | What to do |
|---|---|---|
| 1/4-inch shank bit | 1/4-inch collet/nut | Install 1/4-inch collet/nut, then tighten securely |
| 1/2-inch shank bit | 1/2-inch collet/nut | Install 1/2-inch collet/nut, then tighten securely |
| Bit slips while routing | Wrong size or worn collet | Recheck shank size; inspect collet for wear and replace if needed |
Matching the correct shank and collet on your Craftsman 32017543 helps prevent bit slippage, chatter, and poor cut quality. It also reduces the chance of damaging the collet, nut, or motor shaft.
If you need replacement parts (such as a collet, collet nut, switch, or brushes), start with the parts list for model 32017543, or search by model number on Sears PartsDirect.

How to remove collet from Craftsman router?
To remove the collet from your Craftsman router model 32017543, unplug the router, remove the motor from the base, lock the spindle, then unthread the collet/nut assembly counterclockwise until it comes free from the spindle shaft. See the step-by-step procedure in the owner's manual.
- Unplug the router (never service the collet with power connected).
- Remove the motor from the fixed base or plunge base.
- Set the motor upside down with the collet/nut pointing up.
- Press and hold the spindle lock button to lock the spindle shaft.
- Use the wrench on the collet/nut and turn counterclockwise.
- If a bit is installed, loosen the collet/nut and remove the bit first.
- Keep turning the collet/nut counterclockwise (with the spindle lock engaged) until the collet/nut assembly is free from the spindle shaft.
The collet/nut on this router is self-releasing, so you do not need to strike it.
Try these fixes:
- Loosen the collet/nut a little more until the bit releases.
- Remove dust and pitch from the bit shank; debris can “glue” it in place.
- Blow out the collet area with compressed air (wear eye protection).
- Wipe the tapered inside of the collet/nut with a tissue or fine brush.
- Apply a small amount of machine oil to the spindle shaft if it looks dry.
From time to time, we recommend:
- Keeping the bit shank, collet/nut, and spindle clean and dry
- Removing wood chips, dust, grease, and rust before installing a bit
- Replacing a worn or damaged collet/nut promptly
| Task | When to do it | What it prevents |
|---|---|---|
| Clean collet/nut taper | After dusty routing or stuck bits | Bit seizure, runout |
| Inspect collet/nut for wear | Monthly for frequent use | Bit slipping |
| Light oil on spindle shaft | When spindle looks dry | Thread galling, corrosion |
A clean, undamaged collet/nut grips the cutter bit correctly. That reduces vibration, improves cut quality, and helps prevent the bit from slipping during routing.

What is a Sears Craftsman router?
A Sears Craftsman router is a handheld woodworking power tool that spins a cutter bit at high speed to shape edges and cut grooves. For Craftsman model 32017543, the operator manual describes an 11.0-amp variable-speed router designed for controlled, precise routing.
We use a router for many common shop tasks, including:
- Cutting grooves, dadoes, and slots
- Trimming laminate and edge banding
- Rounding over, chamfering, and profiling edges
- Cutting rabbets and decorative details
- Following templates with guides or bushings
The 32017543 owner's manual calls out these key characteristics and safe-use limits:
- 11.0 amp motor with variable speed
- Uses 1/4-inch and 1/2-inch shank router bits (via the included collets/nuts)
- Sub-base opening is 1-1/4 inches; larger-diameter bits require a different sub-base
- Safety guidance to keep the speed dial low (typically 1 or 2) when using larger-diameter bits
| Item | What to use | Why it matters |
|---|---|---|
| Bit shank size | 1/4 in or 1/2 in | Matches the collets/nuts designed for this router |
| Sub-base opening | 1-1/4 in opening | Bits larger than the opening can damage the sub-base and tool |
| Larger diameter bits | Larger-opening sub-base; low speed setting | Helps maintain control and reduces risk |
Using the correct shank size, keeping bit diameter compatible with the sub-base opening, and matching speed to bit size helps prevent chatter, burning, and loss of control while improving cut quality.
