Cutting Tools (Types Classification, & Characteristics)
A cutting tool is a device with a blade at the end of the shank to cut material. Diamond/CBN, high-speed tool steel, cemented carbide, ceramic, and ceramics are part of the blade material.
Machining is a process used in manufacturing activities. In this process, by shearing from a preformed blank in the form of a chip, the excess portion of the material work is gradually eliminated. In machining, a heavy, robust, and oblique or wedge-shaped tool, referred to as the cutting tool, is used to compress the material to shear off the excess layer.
The ultimate aim of the cutting tool is to wedge off a certain layer of the work of the material to give it a particular shape as a finished product. To allow easier removal of the unwanted substance layer by applying minimal effort, the tool is wedge-shaped with a fine tip.
In order to learn about the cutting tools types, classifications and characteristics let's move on to the article.
What is a Cutting Tool?
A cutting tool is a sharp-edged, wedge-type device that is used to shear off the workpiece from the excess material layer to give it a certain scale, shape, and precision. The machine tool is closely focused on it. The relative speed of operation between the cutting tool and the workpiece is facilitated by various mechanical arrangements to perform the cutting action.
Types of Cutting Tools in Workshop
The cutting tool, as the name implies, is used in machining technology for cutting operations. It is possible to use the cutters in various kinds of machining applications. Therefore, based on their respective positions in machining, the cutters have been named accordingly.
Here is a list of the Commonly used Cutting Tools:
Air Saw Blades
Air Saw Blades is a heavy-duty air reciprocating saw that can cut flat and curved surfaces easily. These air saws are designed for high-speed metal cutting requirements. It has a body constructed with aircraft-grade aluminum which makes it highly durable and resistant to corrosion and other chemical actions.
Auger Bits
Auger bits have screw tips that bore into wood easily and twist the complete way along their length to make the hole clean and to remove as much of the chips and dust that are produced during drilling as possible.
The auger bit features dual cutting blades which make balanced drilling and nail cutting a breeze.
Hack Saws
A Hacksaw is a type of hand tool designed exactly for cutting through materials such as plastic, steel, and other metals. These Bi-Metal Hacksaw are a variant of the traditional hand saw, typically used for cutting wood, and have become a staple tool for professionals and hobbyists alike.
Hacksaw blades are available in 12-inch sizes and a variety of teeth for cutting materials.
Hole Saws
A Bi-Metal Cobalt Hole Saws are a type of hand tool with a 4/6 variable tooth pitch and 1-1/2" cutting depth designed exactly for cutting through materials such as plastic, steel, and other metals.
Hole Saw Arbors
The Hole Saw Arbor is a type of hand drill tool that connects a drill chuck to the actual saw itself. Also known as a mandrel. Hole saw mandrel is versatile and can be used with several Hole saw diameters.
It allows you to change saws easily and efficiently since there is no need to remove the arbor from the device.
Recip Blades
Recip Blades are made of high-quality steel, combination set provides a selection of blades for common applications. Metal Reciprocating Saw Blades are compatible with all reciprocating saw brands.
These Bi-Metal reciprocating saw blades are MADE IN USA. This cutting wheel is a great addition to any saw set and ideal for use with metal, plastic, wood, and drywall.
Spade Bits
A wide range of Spade bits flat blades in the market. These spade bits are generally used by retailers such as electricians and plumbers for drilling holes in studs in walls for running wiring or pipes.
The flat paddle design features a sharp cutting edge, ensures the hole smooth clean.
TCT Hole Cutters
TCT Hole Cutters cut into sheet metal, wood, and other materials with ease. As cutters, they are efficient as they cut the circumference of the hole Includes hole cutter, hex key, and pilot bit.
These hole cutters have become the type to have at your disposal for cutting into metal. These hole saws make precision, accurate, clean round holes in metal & steel sheets. It used by metal fabrication experts and those who prefer the highest standard for their tools.
TCT Saw Blades (Aluminum, Steel, Wood)
Tungsten carbides tipped (TCT) blades are specially designed to cut aluminum, wood, steel & other metals including bar, die-castings, extrusion, and sheet. These Wood Cutting Tools are ideal for Aluminum and Non-Ferrous Metals.
Drill
This cutter performs the drilling operation and so is associated with the drilling, milling, or lathe machine.
Chop Saw
The chop saw is a stationary rough cutting tool that can be used to cut materials to length. A chop saw features a spinning abrasive or sharpened blade suspended from an arm above a stationary base.
Mill (or Milling cutter)
This tool is used for the milling tasks on the milling machine.
Fly cutter
This tool does the task of fly milling on the milling machine.
Shaper
This cutter is for the workpiece to provide precise shape and precision and is done on the shaping unit.
Planer
It is similar to a shaper.. In this method, however, the larger workpieces that move during the process are used, while the cutter moves in shape.
Boring bar
To perform the boring process, this cutting system is carried out on the boring or drilling rig.
Reamer
This is for the reaming procedure on the drilling machine to be carried out.
Broach
This is for the reaming procedure on the drilling machine to be carried out.
Hob
This cutter performs the hobbing operation on the hobbing machine.
Grinding wheel
This grinding tool is an abrasive device used on the grinding machine for the grinding operation.
Welders
To cut through the steel, welding tools use an ultra-hot, intense flame. Without physical resistance, a welder's flame will melt its way through hard and dense materials. This typically results, however in rough or dirty edges.
Classification of Cutting Tools
In many ways, Cutting Instruments may be classified. The most generic method, however, depends on the number of core cutting wedges involved at a time in the cutting process.
Based on this as described below the cutters are classified into three sections:
Single point cutting tool
This type of cutting tool has a single main cutting edge that performs simultaneously in the cutting action. The boring tool, slotting tools, turning tools, fly cutting tools, and more are some of the cases of the single-point cutter.
Double point cutting tool
As the name suggests, this cutting tool consists of double cutter edges, that take part in a single pass of the cutting process at the same time. The drilling tool is an example of a dual point cutter.
Multi-point cutting tool
There are more than two core flutes (cutting edges) in this cutting tool that can shear off the excess material layer from the workpiece simultaneously in one pass. Broach, milling wheel, a milling cutter, gear hobbing cutter, and others are some instances of the multi-point cutter.
Characteristic of Cutting Tool Materials:
You need to take care of the material property, strength, and quality when you choose or make a cutting tool: Below are some characteristics of the cutting tool:
- Even at higher or lower temperatures, cutting tools should have elevated strength and hardness.
- None of the material properties (ductility, hardness, strength) of the long rung should be changed.
- It should have high strength and should be able to resist shock and vibration.
- The price of the tool should be cheap.
- Fabricated quickly.
- It needs to have a low friction coefficient.
Conclusion
That was all about the styles and classifications of the cutting methods. If you are new to machining technology, then this article can help you learn more about cutting tools from the center, which is needed by the primary machining tool.
