How to Remove Bits From a Skil Router

Removing a stuck or worn bit from a Skil router is a routine maintenance task that every woodworker needs to know. This guide covers the safe, correct procedure for both fixed-base and plunge routers, including how to use the spindle lock, loosen a seized collet, and avoid damaging the bit or the tool. You’ll need a few common tools and about five minutes.

What You’ll Need

Skil router (fixed-base or plunge model)
Two open-end wrenches (typically 19 mm and 22 mm, but check your manual)
Safety glasses
Work gloves (optional but recommended)
Penetrating oil (e.g., WD-40) if the collet is stuck
Soft cloth or rag
Rubber mallet or block of wood (only if the bit is seized)

Step-by-Step

Unplug the router. This is non-negotiable. Never attempt to remove a bit while the router is connected to power. If it’s a cordless model, remove the battery.
Put on safety glasses. Bits are sharp, and debris or a slipping wrench can cause injury.
Identify the collet type. Most Skil routers use a standard ER-type collet with a locking nut. Some models have a spindle lock button; others require two wrenches. Check your owner’s manual if unsure.
If your router has a spindle lock: Press and hold the spindle lock button (usually located near the collet nut). Rotate the collet nut by hand until it clicks into the lock. Keep the button pressed.
If your router does not have a spindle lock: Use two wrenches. Place one wrench on the collet nut and the other on the spindle flats (the hexagonal or square section just above the nut). Hold the spindle wrench steady while turning the collet nut counterclockwise (as viewed from the bottom of the router).
Loosen the collet nut. Turn it counterclockwise about half a turn. You do not need to remove it completely—just enough to release the bit.
Remove the bit. Pull the bit straight down out of the collet. If it doesn’t slide out easily, gently wiggle it while pulling. Do not force it sideways, as this can bend the bit or damage the collet.
Clean the collet and bit shank. Wipe off any dust, resin, or rust with a soft cloth. This prevents future sticking and ensures a secure grip when you install a new bit.
Store the bit safely. Place it in a case or wrap it in cloth to protect the cutting edges.

Common Mistakes

Forgetting to unplug the router. This is the most dangerous mistake. Always disconnect power first.
Using the wrong wrench size. This can strip the nut or spindle. Use the exact sizes specified in your manual.
Turning the collet nut the wrong way. It’s counterclockwise to loosen, but if you’re looking from the bottom, it may appear clockwise. Double-check before applying force.
Overtightening the collet nut when installing a bit. This makes removal difficult. Tighten only until snug, then give it a slight extra turn.
Pulling the bit sideways. This can bend the shank or score the collet. Always pull straight down.
Ignoring a worn collet. A collet that’s cracked or has lost its grip will cause bits to slip or seize. Replace it if damaged.

Tips

Use the spindle lock properly. If the lock button doesn’t engage, rotate the collet nut slightly until it clicks in. Never force it.
Apply anti-seize compound to the bit shank before installation to prevent corrosion and sticking.
Keep the collet clean. After each use, wipe the inside of the collet and the bit shank with a dry cloth. A tiny brush can help remove embedded dust.
If the bit is stuck, don’t panic. Apply a few drops of penetrating oil around the collet nut and let it sit for 10 minutes. Then try again.
Use a rubber mallet for stubborn bits. After loosening the nut, tap the end of the bit gently upward with a rubber mallet to break the grip. Never use a metal hammer.
Mark the collet nut position with a permanent marker before removal. This helps you reinstall it with the same torque.

Troubleshooting

The collet nut won’t turn. This usually means it’s overtightened or corroded. Apply penetrating oil and let it sit. If it still won’t budge, try using a longer wrench for more leverage, but be careful not to strip the nut. If the nut is damaged, you may need to replace the collet assembly.

The spindle lock won’t engage. The lock mechanism may be jammed with dust. Blow it out with compressed air or clean it with a small brush. If the button is broken, use the two-wrench method instead.

The bit is stuck in the collet even after loosening the nut. This can happen if the bit shank has a burr or if resin has glued it in. Tap the end of the bit gently with a rubber mallet (while the nut is loose) to break the bond. If that fails, apply heat with a heat gun (not a torch) to soften the resin—be careful not to overheat the collet.

The collet nut is spinning freely but the bit won’t come out. This suggests the collet itself is damaged or the threads are stripped. Inspect the collet for cracks or wear. If damaged, replace the collet and nut as a set.

You stripped the collet nut. Stop immediately. Do not continue turning. You’ll need to replace the collet nut and possibly the collet. Contact Skil customer support or an authorized service center for parts.

Frequently Asked Questions

Do all Skil routers have a spindle lock?

No. Some older or budget models don’t. They require two wrenches. Check your manual or look for a button near the collet.

What size wrenches do I need?

Most Skil routers use 19 mm and 22 mm wrenches, but it varies by model. Check your manual or measure the flats with a caliper.

Can I use a power tool to loosen the collet nut?

No. Always use hand tools. A power tool can over-torque and damage the collet or the router’s spindle.

How often should I clean the collet?

Ideally after every use, especially if you’re working with resinous woods. At minimum, clean it every time you change bits.

Why does my bit get stuck every time?

This is usually due to a dirty collet or overtightening. Clean the collet and shank, and use a torque wrench or just snug it firmly—not with full force.

Can I remove a bit without unplugging the router?

Never. Even if the switch is off, a faulty switch could power the router on. Always unplug or remove the battery first.
