I can still remember the day 1 purchased my first table saw (a dream come true). I was so excited I could hardly stand it. After making a cut on the closest piece of wood, 1 examined the piece expecting to find the perfect edge. Boy was I surprised! The finish was so poor I would have been better off using a hand saw.
I double checked every possible adjustment on the table saw, only to discover that the culprit was the blade, not the saw. So I decided to stretch my already taxed budget, and buy a good saw blade.
After listening to a sales pitch on the virtues of using carbide-tipped blades, I described to the salesperson the type of cutting I would be doing most often so I'd be sure to get the right blade. "No problem," he said, "here's the saw blade for you." "Yes siree bob, that sure looks like a nice blade," I thought.
So much for looks. I found out (too late) that the blade was designed for a totally different purpose than I wanted. The end result was that I had wasted $50 on a blade which now hangs on the wall collecting sawdust rather than making it.
I decided there had to be better sources of information on how to choose the correct saw blade, but after looking, I really couldn't find one. That's when I decided to contact some professionals: Carlo Vend-itto, Executive Vice President of Freud, Bob Pirrone of Forrest Manufacturing Co. (both carbide-tipped saw blade manufacturers), Paul Naylor, President of Keo Saw (a professional sharpening service), and two metalurgists. I figured if anyone could tell me how to both determine the quality of a saw blade, and how to choose one, they could.
Saw blades fall into two general categories: steel saw blades, and carbide-tipped saw blades. The only difference between the two is that carbide-tipped blades have small pieces of tungsten carbide brazed to the steel body to form the cutting edges. The effect this has on performance is dramatic.
retaining an edge. Retaining an edge longer than a steel blade (usually at least 10 times longer) is one of the biggest ad vantages of a carbide-tipped blade. That ability results from the extreme hardness of the tungsten carbide.
QUALITY OF THE CUT. The quality of CUt produced by a saw blade relates directly to the sharpness of the tips. This is where carbide-tipped blades can make a big difference, since they seem to stay sharp forever.
Okay, so carbide-tipped blades outshine steel blades in every aspect, right? Well not quite. The most obvious drawback to carbide-tipped blades is their initial cost — usually $35 to $170. Whereas steel blades run $5 to $20.
But comparing only the initial costs can be deceiving. Carbide-tipped blades require sharpening less often than steel blades. So, in the long run, the cost of.a carbide-tipped blade is often no more than a steel blade when you figure in the cost of repeated sharpening.
