In this Toolstop University Video Guide, we continue with the theme of grinders. Click here to read our grinder safety checklist.
We’re now going to focus on the discs you use in your grinder and how to make sure you understand what you’re doing, what you’re using and are operating only on the safest levels. We’ve got 9 tips for your safety below.
Be aware, this guide isn’t exhaustive and remains your responsibility to follow all safety instructions supplied by your grinder’s manufacturer and that you adhere to all on-site Health and Safety Guidelines when using a grinder. Correct PPE is also a must.
The basis of this guide is a video that Martin from Makita took us through where he shares his knowledge of grinder discs and safety.

To recap, then, here’s what your grinder disc safety checklist should look like:
- Look for the manufacturer’s name or logo on the disc. This serves as accountability; you know it’s a genuine part and has been manufactured according to proper safety guidelines
- Check the size of the disc. You’ll find that on the disc’s label. Correspond that size with the maximum size of disc that you’re grinder can take. This will be printed on the grinder’s manufacturer’s sticker
- Check the speed of the disc. Look out for the maximum RPM printed on the disc’s label. Again, correspond this with the speed rating of your machine. The speed rated on the disc should be greater than the speed of your machine
- Check the sell-by/use-by date. This will be stamped on the boss of the disc
- Check the code of the disc. This will inform you of the type of application the disc was manufactured to perform, including the grit and the hardness of the disc. If in doubt, refer to the manufacturer’s website in order to decipher the code
- Inspect the condition of the disc. You’re looking out for cracks or chips. You’re also on the lookout for water or oil contamination. Any of these issues will seriously undermine the integrity of the disc and it could burst in use
- Insert the disc. Fit the disc properly, paying attention to the flanges, making sure you’ve inserted them in the correct order
- Tighten the disc. Finger tighten the disc, then using the spanner gently tighten. There’s no need to overtighten
- Spin the disc. Give the disc a few spins to make sure that its properly fitted and isn’t camming out
