Frequently Asked Questions

Does the Craftsman grinder have safety features?

It has a slide switch and a tool-free adjustable guard. No electric brake, no kickback stop, no anti-vibration. For $59, you get basic functionality. The safety features on the $100+ DeWalt and Milwaukee models are worth the upgrade if you use a grinder regularly.

Can I use the Craftsman grinder for tile cutting?

With a diamond blade, it'll cut ceramic tile. Porcelain tile is harder and generates more heat. A wet tile saw is a better tool for porcelain. An angle grinder works for notches and L-cuts where a tile saw can't reach.
