  • CT-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
  • C5 grade uncoated carbide tip for roughing and heavy machining of steel and steel alloys
  • Right-hand cutting direction for right-to-left feed
  • Positive rake angle provides a sharp edge for making continuous cuts
  • Square steel shank fits square toolholders


The CT-style C grade carbide-tipped brazed tool bit has a right-hand cutting direction for roughing or heavy machining when performing cutoff or grooving on steel and steel alloys. The CT-style, also called COR-style, tool shape has a -degree end cutting angle and a taper on the non-cutting side for cutoff or grooving of solid bars and tubing stock, and a right-hand cutting direction for right-to-left feed. The tool has a positive, -degree rake angle that provides a sharp edge for making continuous cuts. The tool has a C grade uncoated carbide tip, which provides good resistance to shock and wear for roughing and heavy machining of steel and steel alloys. 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) B22. 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.

manufactures standard single-point brazed carbide-tipped tools, and precision ground cutting tools and inserts. The company, founded in 9, is headquartered in Canton, OH.

I have been using a 1/8" cut 10% cobalt HSS cut off tool since purchasing my small 12" X 36" lathe back in '91. I saw this little cutie, which looked to be a 1/2" shank with a carbide cut off extension that just might fit in my wee 4 way tool post.. So, I simply HAD to try it. (The description did say "0.5" Square Shank". )
When I opened the package did I get a surprise! This puppy is 1/2" wide by 1" deep and has a 5/16" width cut. I'm not sure my wee little lathe would have enough horsepower!
The good news is that it looks to fit directly into my American Tool Post without any additional tooling. I still haven't tried it out as I simply haven't had the need (or the urge to experiment). But, it looks to be of good quality and quite robust.

I am sure this is a good bit, however, it was not described accurately. The height is 1" and the width is 1/2" Not a square shank as described.
