How-to Use Your Angle Grinder on Wood, Metal and More!
The Angle grinder, also known as a disc grinder, is a powerful little handheld tool used for grinding, sanding, abrasive cutting, and polishing wood, metal and more. Originally designed to be used with rigid abrasive grinding and cut-off discs, newer more portable battery operated angle grinders have encouraged the development of a wide variety of attachments and cutters.
I purchased my first angle grinder for cutting and grinding metal parts around the garage. At the time, I had no reason to know I could use it for anything else … it wasn’t until I started building log homes and log furniture that i learned how I could use my angle grinder on wood. It’s even come in handy more than a few times cutting concrete and tile.

I use the angle grinder more than any of the other tools in my shop.

Angle grinders typically have an adjustable safety guard and an additional side-handle for two-handed operation. Operators must never remove the safety guard and always follow all safety instructions that come with the angle grinder!
Flap-wheels and flap disks are abrasive disks, used on Angle Grinders for sanding wood and metal finishing. Unlike the simpler flat sanding disks, made from a single circular flat abrasive sheet, flapwheels consist of multiple overlapping smaller pieces or ‘flaps’, bonded to a central hub, or axle.
