- Silicon carbide is more aggressive and cuts faster than aluminum oxide
- Type 1 wheels are straight (also called flat) cut-off wheels, and are used for peripheral grinding
- Reinforced design helps provide safety, strength, and straight cuts
- Resin bonds soften under the heat of grinding, releasing dulled abrasive grains
- Intended for use on circular saws
Norton Masonry Type 1 circular saw wheels use sharp silicon carbide, which is suitable for use on masonry materials like concrete, brick, and asphalt.
Reinforced cutoff wheels are designed to resist breakage caused by severe cross-bending and are required on any operation where the work is not securely clamped. Resin bonds are organic bonds that soften under the heat of grinding, releasing dulled abrasive grains. Because of its forgiving nature, only an organic type bond is used in cutoff wheels. The resin-bonded wheel is more resilient than a vitrified wheel. The manufacturing term for a resin bond wheel is “cured,” meaning the wheel has been heated to less than 500 degrees F. Straight (also called flat) wheels are the most common grinding wheel shape. Straight wheels are used for grinding on the periphery, or outside boundary edge, of the wheel and produce a slightly concave surface, called hollow ground, on the workpiece. These wheels can be used for cutting off, tool grinding (between centers or centerless), and removing mold marks and sand from castings, among others. They are frequently used with grinding machines. Using a harder grade wheel increases wheel life but also increases burn and requires more power, and decreases cut rate. Burn is the effect on a workpiece from thermal stress as abrasive cuts or rubs material away. The damage ranges from discoloration to cracking of the workpiece.
Silicon carbide is a sharp, aggressive grain that offers high penetration, fast cutting, and high material removal even under light pressure. It is commonly used with softer materials like brass, plastics, and rubber, and abrasive materials like glass and enamel, but can wear out faster that aluminum oxide when used on wood.
Abrasives are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse and are used for removing excess material and shaping a part. High grit numbers like 400 are fine and help to create a smooth surface finish.
Norton Abrasives manufactures a wide variety of sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. In 1990, Saint-Gobain purchased Norton, keeping its manufacturing facilities and offices in the same location. Norton/Saint-Gobain has been recognized as a Global 100 Sustainable Company, as well as earning ISO 9000 and 14001 certification for quality and environmental management standards.

Which power tool(s) should I buy?
I’m 15 years old, and am already in Industrial Tech. 2 at my High school. I love all the saws, and building something out of nothing. So, since I can only do this 48 minutes a day, I wanna try and buy my own power tools. My dad is experienced with wood working, and will help me. I think a want a circular saw and sabre saw. I just want to build simple things for right now, a small stool, table, picture frames, something like that. What would be the best power tools for someone with moderate experience on a tight budget? Thanks!
Suggestion by Erik
check out the pawn shops
you might be able to get your tools cheap
a drill
a circular saw
and a dremal tool
will get you thorugh mose projects
save up to buy a chop saw and a lathe
Suggestion by TD
Erik is right – check out the pawn shops. They will have every tool you need for pennies on the dollar. Craig’s list has good deals as well.
A miter saw is a must as is a circular saw and drill. A jig saw is good to have as well. I can build most anything with these basic power tools (and a few had tools)
Suggestion by Darren
Yup, pawn shops are a good place to go and look. At 15 though, I would suggest bring your dad with you, pawn brokers aren’t known for making the most honest deals out there. I’ve done a lot of pawn shopping, I like finding the deals, but most of the merchandise doesn’t have price tags because they want you to name a price and then the deal making begins. Make sure you do your homework on retail prices so you know if your getting ripped off and remember to ask about warranties. I like RIGID tools, I used DEWALT for a long time and found they broke down on me annually. I bought a RIGID drill three years ago and haven’t had a problem. Last year I bought a radial saw and framing nailer and had no problems at all. Hope that helps.
Suggestion by Scott B
For me I would rather save up and buy a good brand tool rather than buy one that is of lesser value and will not last. Till you can get money to buy what you want/ need, see about borrowing from friends or family, just be sure to return them in as good if not better condition. I would buy a miter/chop saw, a drill and a table saw. Have fun.
