Using Die Grinders For Cutting And Grinding

A die grinder is an essential cutting and grinding tool. Most often used to polish and buff the inside of cylindrical objects, it is also used to grind, sand and hone metal, plastic and wood. This versatile tool enables sculpture-like contouring, eases the fabrication process and helps in cut-off of bar stock. Die grinders are usually pneumatically driven handheld power tools although some varieties include electric and flexible shaft drives.

Use

When material, especially metal, is cut, resultant small spurs may create issues for connections. A die grinder enables proper installation by grinding the spurs away and smoothing the area.

RPM

Rotations per minute (RPM) measures the frequency of spins while a die grinder is in use. Lower RPMs facilitate fine grinding and finishing tasks while die grinders with RPMs between 10,000 and 20,000 are suitable for minor buffing jobs. Versions with over 20,000 RPMs are useful to cut metal or remove burrs from it.

Types

Angle die grinders are the most popular of these tools. They have a spindle that is mounted parallel to the body of the tool, on the surface of the cutting wheel. Angle die grinders are used for cutting as well as both light and heavy grinding. They are also incredibly useful for working in cramped spaces. A lightweight angle die grinder with variable speed and a ball bearing construction is easiest to use and most durable.

Like all other air tools, air die grinders are powered by air as opposed to manual force or electricity. Air die grinders are not only smaller and more durable but also help to complete the job faster and in a more time-efficient and cost-effective way.

Cordless die grinders are relatively recent introductions to the market. Their structural housing design delivers great strength at minimal weight. Including the variable speed functionality, often with safety locks, these are very safe to use. Additional protection is offered by microprocessor controls that monitor tool operation as well as temperature in cordless die grinder. Good vendors usually offer warranty and compatibility between tools, batteries and chargers as well as advanced technology and design in their cordless die grinders.

Safety

It is imperative for the die grinder user to protect his eyes with safety glasses or a face shield while working with the tool. Since die grinders are usually loud, hearing protection devices such as ear plugs or headphones are desirable. For skin protection, work gloves and insulation clothing enhance safety. Paper masks or respirators offer protection for respiratory and alimentary tracts.

Whether using a die or cordless angle grinder, the user must maintain a strong hold on it and keep his fingers out of the range of the grinding nose. While not in use, the tool must be switched off and unplugged.

Without a doubt, die grinders are necessary tools for professional and amateur metalworkers and woodworkers. With basic safety precautions, die grinders can make cutting and grinding jobs simple, quick and harmless.
