There are a few small scale machines designed for DIY sharpening of carbide saw blades, and one that I know of is made by Viel (www.vieltools.com) I’ve never used this machine personally, but a friend of mine with a welding shop just bought one. I’ll know better how it works in a few months. Besides having the necessary sharpening equipment, it does take skill to restore carbide saw blade performance. Some blade designs are easier than others to sharpen, but either way you should expect to invest some learning time for you get good.

Methodology: A total of 258 ProTaper Universal (PTU) and ProTaper Gold (PTG) Shaping instruments were used. Bending behaviour was assessed to determine the appropriate displacement associated with a 2 N force in lateral cutting. Ten instruments of each type were used in lateral action for 60 s against bovine dentine or plastic substrates four consecutive times producing four notches in each specimen. Ten further instruments of each type were used in on axial action in four standardized simulated root canals fabricated from 4-mm thick plastic or dentine discs. Both tests were performed at 300 rpm in a computer-controlled testing platform. Notch area and torsional load were compared with Student's t-tests. Repeated measures ANOVA was used to compare cutting efficiency across the four different time-points. Pearson correlation coefficients between substrates were also determined.

There are two ways that the teeth on carbide blades can be sharpened. You can send a blade out to a dedicated sharpening shop, or you can invest in the equipment to do the work yourself. I have almost a dozen carbide saw blades in my woodworking shop, and a couple have been with me for almost 20 years. I’ve always sent my blades out to be sharpened. Costs typically run from $10 to $15 per 10- or 12-inch diameter blade and the results have always been excellent. Performance after a fresh sharpening job is at least as good as when the blade was new. I don’t live anywhere near a sharpening shop, so I wait until I have 3 or 4 dull blades to package up and ship by mail.

Results: For lateral action, all three PTG instruments cut significantly more effectively (P < 0.05) than PTU on the plastic substrate. S1 and S2 PTG cut significantly more after 120 and 180 s (P < 0.05) on bovine dentine substrate. For axial action, S1 and S2 PTG were significantly more efficient in cutting at 180 s on plastic and 120 s on bovine dentine (P < 0.05).

Inexpensive carbide saw blades of the sort used in hand-held circular saws are designed to be used then recycled, while more expensive carbide blades for tablesaws and chopsaws are built to be resharpened 4 or 5 times. Even in a professional shop, these blades deliver years of service.

How to sharpen carbide saw bladeby hand

Over the last 30 years, carbide saw blades have almost completely taken over from regular steel saw blades for woodworking because carbide lasts so much longer between sharpenings. In this case the term “carbide” refers to an extra-hard alloy that’s used to form the cutting teeth arranged around the circumference of a blade. Carbide teeth are typically brazed to the main body of the blade, and it’s the incredibly hard nature of carbide that makes these teeth last so long, while also presenting a challenge when it comes to sharpening.

Why would someone with a welding shop need to sharpen carbide saw blades? Over the last few years carbide metallurgy has progressed to the point where it’s tough enough to handle heavy ferrous metal. So-called “dry cut” carbide blades are available for cutting all kinds of steel, both solid and hollow. Performance is quite surprising and much better than traditional abrasive wheels. Carbide blades cut faster, they generate far fewer sparks, they’re very accurate and leave no burr. The cut surface is also cool to the touch.

Aim: To isolate the effect of metallurgy in lateral and axial cutting efficacy against plastic and bovine dentine substrates by comparing two rotary systems with identical design but manufactured with either conventional nickel-titanium or heat-treated gold alloy.

Conclusion: Instruments made from heat-treated nickel-titanium gold alloy had equal or greater cutting efficiency when compared to those made from conventional nickel-titanium.
