Angle Grinder

Basics

• A Handheld Power Tool that is essentially a motor at an angle with handles for easy manipulation, and Mechanical Guarding for safety
  • Dust Extraction can also be included

Metal

• Can be used for Removing Mill Scale , Metal Polishing / Rust Removal , Weld Reworking , and if a Cut-Off Wheel is used even light Metal Cutting
• Main Attatchments for this are:
  • Grinding Disc (Also called a "hard rock" disk since they are essentially one solid composite rock)
  • Flap Disc (Essentially Sand Paper in a disc in the form of "flaps", similar to an Orbital Sander / Rotary Tool in use, but a bit more "intense" in how far you can "push it") ( User: Eric speaking here, personally from 1 year or so of grinding down mild steel for welding at school, i found these burnt up and ended up with a surface finish with whirls in it unlike the more mirror like one could get with a hardrock one (with enough finesse, although i'd need to do a time study or something to see which is faster) (Also i saw one of those Cordless Handheld Bandfiles towards the end, and that or a rotary tool are a bit better for the sanding role in a welding context, and a Random Orbital Sander in a large Surface Prep role)
  • Wire Wheel Angle Grinder Discs
• Standard is grinding down metal (Essentially an alternative to a Chipping Hammer for welding, or a Needlegun for Rust Removal etc
  • They are fast, but quite messy (and mess i mean wire shards being launched at some absurd RPM and thus energy...spooky stuff
    • Supposedly Encapsulated Wire Wheels are better in this regard, granted then Microplastics, make one with Wax maybe?
• Grinding wheels with diamond or CBN grains are called superabrasives. Grinding wheels with aluminum oxide (corundum), silicon carbide, or ceramic grains are called conventional abrasives. Wikipedia - [1]

Wood

• But - there are also wood blades! See example - [2]
• There are chainsaw, diamond cup, tungsten carbide, others that function like a flat router blade, and more - [3]

Concrete

• Diamond blades do concrete

Internal Links

• Rotary Tool (similar use cases and versatility, but more precise)
• Handheld Cordless Bandfile (Optimal for Sanding in Small Spaces, such as a Groove Weld etc)
• Needlegun (A Hand Tool Optimal for use as the power tool equivalent of a Chipping Hammer or for Paint Removal and Heavy Rust Removal
• Random Orbital Sander / Buffer (Not often optimized for Metalwork , Moreso Woodwork and Composite Materials , but it can be done
• Surface Grinding / CNC Finishing of Castings
