Product Description

The American Carbide Tool E-style K68 grade carbide-tipped brazed tool bit has a neutral cutting direction and a sharp tip with a 60-degree angle for fine threading on cast iron and nonferrous materials. The E-style tool shape has a tip with a 60-degree angle ground to a sharp point for fine threading. It can also be used for chamfering, notching, and undercutting. The tool has a positive, 3-degree rake angle that provides a sharp edge for making continuous cuts and a neutral cutting direction for right-to-left or left-to-right feed. The tool has a Kennametal K68 grade uncoated carbide tip, which provides good resistance to wear for machining on cast iron and nonferrous materials. Carbide is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The tip is brazed to a square steel shank that fits square toolholders.

Brazed tools, often called single-point brazed carbide-tipped tools, are used for metal shaping on lathes or screw machines. These single-point tools have a cutting edge at one end that is a carbide tip brazed to a steel shaft. They come in multiple geometry styles for cutting different shapes and are identified by a lettering standard that conforms to American National Standards Institute (ANSI) B212.1 specifications. The tool has a side cutting edge and end cutting edge, with the tool shape style defining which cutting edge is principal and auxiliary. Brazed tools are available in three hand options: right, left, and neutral. A right-hand tool has its principal cutting edge on the right side of the tool to feed into the workpiece from right to left, a left-hand tool feeds into the workpiece from left to right, and a neutral-hand tool will cut either left to right or right to left. The side cutting and end cutting edge angles, in combination with the angle at which the tool is positioned in relation to the workpiece (also called the lead angle), influence the tool's cutting shape and action. Rake angles are the degree of inclination of the face toward or away from the cutting edge. They may be positive for sharp, continuous cuts, negative for heavy, interrupted cuts, or neutral for a true 90-degree cut. The tip, or nose, of the tool performs the finish cut on the workpiece. In general, a larger tip radius will produce a better surface finish and permit a faster feed rate than a smaller tip radius.

American Carbide Tool manufactures standard single-point brazed carbide-tipped tools, and precision ground cutting tools and inserts. The company, founded in 1953, is headquartered in Canton, OH.

Size: E 7 Verified Purchase
My little lathe uses a 7/16 square tool bit, it has been harder to find than the standard 1/2 or 3/8 sq bits...not everyone handles this size and I like this shape for threading parts without shimming or milling the shank down to 7/16 thickness. The shipping was fast and fair, my order arrived in good condition
