These cutting tools are held stationary by what is known as a tool post which is what manipulates the tools to cut the material into the desired shape. Single edge cutting tools are used mainly in the turning operations performed by a lathe in which they vary in size as well as alloy composition depending on the size and the type of material being turned. There are several different types of single edge cutting tools that are made from a variety of hardened metal alloys that are ground to a specific shape in order to perform a specific part of the turning process resulting in a finished machined part. The majority of these tools are designed exclusively for metals. In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation.

The cutting speed in a drilling operation is the peripheral speed of a point on the surface of the drill in contact with the work. High-speed drills are more widely used due to its greater cutting efficiency. Parallel shank twist drill (Long) 10.00 - IS:599-CS-S-80įor one piece of construction, high-speed steel or carbon steel are used.įor two-piece of construction and cutting portion, high-speed steel is used.įor two-piece of construction and shank portion carbon steel with a minimum tensile strength of 70 kg per sq mm. Standard, made from carbon steel, type S and point angle 80 degrees are designated as follows.

Thus a long-series 10 mm dia parallel shank twist drill conforming to I.S. The drill is made in three types, namely, normal (N), hard (H), soft (S).

Twist drills are designated in the Indian standard system by the series they belong to, the diameter, the I.S. The drill sizes range from 1/64 inch to 5 inches. Number 80 is the smallest having diameter equal to 0.0135 inches and the number 1 is the largest diameter equal to 0.228 inches.Ī being the smallest having diameter equal to 0.234 inches and Z being the largest having diameter equal to 0.413 inches. In the British system, drills are manufactured in three different sizes.

Parallel shank (short series or "Jobbers" twist drill)ĭrills from 0.2 to 100 mm are commonly produced in the metric system. There are different types of drilling machine used to perform the drilling operation which is following below. The Egyptians drilled holes about 3000 years ago by bow drills in 1200 B.C. While performing drilling operation rotating edge of a cutting tool known as the twist drill which exerts a large force on the work clamped on a table. A drilling machine is one of the most important machine tools in a workshop is a material removing or cutting process in which the tool uses a drill bit to cut into solid materials a hole of circular cross-section.
