Metal Cutting
Metal cutting with Sliding Compound Miter Saw- Can it be done?
I'm thinking of buying a Sliding Compound Miter Saw for carpentry, but just wondered if I fit it with a metal cutting blade (like Carbide) will I damage my mitre with hot metal shavings, will the speed be right? etc
Absolutely not. Carbide is 10 times harder than steel, but also very brittle and will come off of the blade like shrapnel if you try to cut steel with it. To cut steel you either need a carborundum disc on a cut off saw, or a metal saw that uses slow speed, lots of torque, a constant supply of coolant, and special blades that are made of hardened steel that can have new teeth ground onto them when they get dull. A miter saw is meant for wood and some plastics and is simply too fast for steel. It would grab as soon as you touched it to the metal and throw it violently in an unexpected direction.
However, you can cut aluminum with a miter saw and I've done it a lot, but you need special blades for that, too. They typically have a negative rake, meaning that the teeth tilt slightly backwards and cut with a slicing motion rather than a chewing one. Aluminum is also prone to gumming up things when it is machined so the blades are designed to resist it. I've cut up to 3/4" thick aluminum on a table saw with no problems other than the smoking hot, razor sharp chips that come off of it. Any time you cut any sort of metal, you have to exercise extreme caution and use all of your safety equipment, like goggles, face shields, ear protection, etc.
