When using a hole saw, it is important to keep the mandrel (the shaft that the saw is attached to) nice and loose. If the mandrel is too tight, it can cause the hole saw to bind and break. If the mandrel is too loose, the hole saw can come off entirely and cause serious injury.
The key is to find the happy medium.
To loosen the mandrel on a hole saw, start by unscrewing the set screw that holds the saw in place. Once the set screw is removed, the saw should be able to wiggle around a bit.
If it is still tight, gently tap the end of the mandrel with a hammer to loosen it up. Once the mandrel is loose, screw the set screw back in place and you’re ready to start drilling!
- Insert the hole saw into the drill chuck
- Hand-tighten the chuck until it’s snug
- Use an adjustable wrench to loosen the setscrew on the side of the mandrel
- Unscrew the mandrel from the hole saw

How do you loosen a mandrel?
There are a few ways to loosen a stuck mandrel, but it usually depends on the type of mandrel and how it is attached.
If the mandrel is held on with a set screw, try loosening the set screw with a hex key or Allen wrench. If the set screw is stripped or the mandrel is still stuck, try heating the mandrel with a torch.
The heat will expand the metal and hopefully loosen the set screw.
If the mandrel is threaded, try unscrewing it with a pair of pliers. If the mandrel is still stuck, try heating it with a torch (as above).
You can also try using a mandrel extractor, which is a tool that grips the mandrel and unscrews it.
If the mandrel is press-fit, the best way to remove it is with a press.
How do you get a stuck hole saw out of a mandrel?
If you’re working with a hole saw and mandrel (a drill bit with an attached shaft), and the hole saw becomes stuck, there are a few ways you can remove it.
First, try to loosen the set screw on the mandrel. This will release the tension on the hole saw and may allow you to remove it.
If the set screw won’t budge, you can try heating up the mandrel with a torch. This will expand the metal and hopefully loosen the hole saw.

This will damage the mandrel, but it may be the only way to remove the stuck hole saw.
Once you’ve removed the hole saw, be sure to inspect it for damage. If the teeth are damaged, you’ll need to replace the saw.
