What Is a Cutter?
Cutters are tools used to cut materials such as wood, cardboard, paper, plastic, metal, etc.
Since there are many types available, it is important to select the type and blade that best suits the application.
If an inappropriate cutter is used for the object to be cut, there is a risk of accidents such as chipping or breaking of the blade. Careful attention should also be paid to the method of use.
Uses of Cutters for Tools
Cutters for tools are used in a wide range of applications, from general DIY to professional workplaces. Using the right one for the intended use will lead to improved safety and work efficiency.
Cutters for tools can cut a wide variety of materials, including plasterboard, wood, and glass, not to mention paper. Recently, types that can cut hard metals such as aluminum and steel have also become available.
Principle of Tool Cutters
Cutters for tools are blades that are used by inserting replaceable blades into the main body. A typical cutter has a blade with a folded edge, and when the cutting ability becomes dull, the tip of the blade is broken off and a new blade is put out for use.
The length of the blade can be adjusted by ejecting the blade from the body with a slider or screw. Blades are available in sizes from 9mm to 25mm, with wider blades applying greater force.
Some cutters have a single blade with no crease in the blade, and are used for cutting plastic and metal. These are generally known as safety blades.
Types of Cutters
Cutters for tools can be broadly classified into two types: the general type that uses a replacement blade with a 60-degree incline and the type that uses a special blade.
1. General Type
Shape of blade
The cutting edge of the blade is inclined at a 60-degree angle. For detailed work, some have a 30-degree incline. There are two types of blade shapes: a normal blade and a black blade with a sharp edge.
The cut black blade is sharp and can cut wallpaper and carpets cleanly, but its durability is inferior to that of the normal blade. In addition, there are two types of blades: one with a crease on the blade to fold the blade tip when the sharpness becomes dull, and one with a single blade without a crease.
Blade size
Replaceable blades generally come in 9mm, 12.3mm, 18mm, and 25mm blade widths. Thicknesses range from 0.25 to 0.38 mm for blade widths of 9 and 12.3 mm, 0.45 to 0.6 mm for 18 mm, and 0.7 mm for 25 mm.
How to lock the blade
There are two types: one is locked with a safety stopper and the other is fixed with a screw. The stopper is easy to operate, but there is a risk of coming off if strong force is applied. On the other hand, the screw type is tightened with a screw and has a strong fixing force.
2. Special Type
Cutter for plastic
These cutters are specially designed for cutting plastic and acrylic panels. The shape of the blade differs from that of a normal cutter. The cutting edge is hooked, and a groove is made while cutting the material.
Saw blade cutter
The replacement blade is a saw blade. It is useful for cutting thin wood. It can also be used interchangeably with regular blades.
Design Cutter
This cutter is specialized for detailed work. It is shaped like a pen, it can be used with various types of blades attached to the tip.
Rotary cutter
This cutter has a circular blade and is used for cutting cloth and other materials. It can also cut into curved lines and is suitable for leather, film, rubber, etc. in addition to cloth.
How to Select a Cutter for Tools
1. Material to Be Cut
Selecting the right cutter for the material to be cut will improve safety and work efficiency. A small type is best for thin materials, while a large type is best for thicker and harder materials. Special cutters should be used for special materials such as plastics.
2. Grip Shape
Cutters for tools should have a comfortable grip that fits your hand. Some tool cutters have non-slip grips made of resin or rubber to prevent slipping, while others have a surface finish. Cutters with non-slip grips are especially suitable for long hours of work or outdoor use.
