About HSS Round ToolBit

HSS Round Tool Bit

We specialize in a comprehensive range of high speed steel tool bits in a variety of shapes, sizes & material. Excellent quality tool bits, recommended for cuts at higher speed, most suitable for heavy work on difficult materials and ideal, general purpose tool bit for machine shops. The term tool bit generally refers to a non-rotary cutting tool used in metal lathes, shapers, and planers. Such cutters are also often referred to by the set-phrase name of single-point cutting tool. The cutting edge is ground to suit a particular machining operation and may be resharpened or reshaped as needed. The ground tool bit is held rigidly by a tool holder while it is cutting. The Round High Speed Steel (HSS) tool bits that we offer, are manufactured using superior grade steel. The Round Tool Bits are extensively demanded because of its durability and perfect finishing. These are available in m2, m35, m42, t42, t1 and other special HSS and Carbide grades.

The overall shape of the lathe tool bits can be rounded, squared, or another shape as long as the proper angles are included. Tool bits are identified by the function they perform, such as turning or facing. They can also be identified as roughing tools or finishing tools. Generally, a roughing tool has a radius ground onto the nose of the tool bit that is smaller than the radius for a finishing or general-purpose tool bit. Experienced machinists have found the following shapes to be useful for different lathe operations.

A right-hand turning tool bit is shaped to be fed from right to left. The cutting edge is on the left side of the tool bit and the face slopes down away from the cutting edge. The left side and end of the tool bit are ground with sufficient clearance to permit the cutting edge to bear upon the workpiece without the heel rubbing on the work. The right-hand turning tool bit is ideal for taking light roughing cuts as well as general all-around machining.

A left-hand turning tool bit is the opposite of the right-hand turning tool bit, designed to cut when fed from left to right. This tool bit is used mainly for machining close in to a right shoulder.

The round-nose turning tool bit is very versatile and can be used to turn in either direction for roughing and finishing cuts. No side rake angle is ground into the top face when used to cut in either direction, but a small back rake angle may be needed for chip removal. The nose radius is usually ground in the shape of a half-circle with a diameter of about 1/32 inch.

The right-hand facing tool bit is intended for facing on right-hand side shoulders and the right end of a workpiece. The cutting edge is on the left-hand side of the bit, and the nose is ground very sharp for machining into a square corner. The direction of feed for this tool bit should be away from the center axis of the work, not going into the center axis.

A left-hand facing tool bit is the opposite of the right-hand facing tool bit and is intend to machine and face the left sides of shoulders.

HIGH SPEED STEEL TOOL BITS are manufactured from the finest quality Cobalt, Molybdenum & Tungsten bearing grades of High Speed Steel. Widely used for machining and variety of ferrous and nonferrous metals. Sophisticated heat treatment provides more life between two regrinds.

Prominent Cutting Performance

Engineered from superior high-speed steel, the HSS Round ToolBit delivers high precision and consistent cutting speed across diverse metalworking applications. Its bright ground finish and optimized surface roughness (Ra 0.8 - 1.6 m) contribute to smooth and efficient operations on lathes, milling machines, and beyond.


Durable, Reusable, and Sharpenable

With a hardness of 62-65 HRC and excellent toughness, this tool bit boasts high wear resistance and a durable cutting edge. Users benefit from its reusable nature and capability to be sharpened multiple times, making it cost-effective for extended use.


Versatility and Customization

Catering to both manual and automated operations, the tool bit can handle cutting, threading, turning, and boring various materials, including mild and alloy steels. Custom sizing and packaging extend its appeal, supporting specialized requirements for distributors and end-users alike.
