Tungsten-Carbide Saws

The teeth of both saws and V-cutters have slight land to give strength to the cutting edge. Saws are hollow-ground for clearance, V-cutters have ample radial relief. When Carbide Saws are used on other equipment than our undercutters, steel supporting washers are recommended to reduce breakage. Spindle speeds may vary from 3,000 to 12,000 r.p.m., depending on Saw O.D. Martindale's Carbide Saw Blades are harder than High Speed Steel Saws, therefore more brittle and should not be subjected to applications where shock may shorten the service life. Use on rigid stationary equipment is recommended.
The compound-land feature, sketched at right, is available on Tungsten-Carbide "U"-slots saw 916" O.D. and up (#18-TC through #116-TC) at a 30% premium in price. Because of this feature, each tooth cuts only 50% of full slot width, resulting in better chip clearance, cooler operation and production increases of up to 60% over the square-tooth Saw. To order, add "CL" to Catalog Number. Minimum thickness 0.015".
