About American Carbide Tool Carbide-Tipped Tool Bit For
The American Carbide Tool CTL-style C2 grade carbide-tipped brazed tool bit has a left-hand cutting direction for cutoff or grooving on cast iron and nonferrous materials. The CTL-style, also called COL-style, tool shape has a 5-degree end cutting angle and a taper on the non-cutting side for cutoff or grooving of solid bars and tubing stock, and a left-hand cutting direction for left-to-right feed. The tool has a positive, 6-degree rake angle that provides a sharp edge for making continuous cuts. The tool has a C2 grade uncoated carbide tip, which provides good resistance to shock and 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.
