WALTER angle grinders: versatile, effective and affordable

A must-have for every hobby workshop

The angle grinder has several common names. It's called a cut-off grinder, a roughing grinder, or, after its inventor's brand name, Flex. It's an essential tool for any well-equipped DIY enthusiast. With its rapidly rotating disc, you can precisely cut and trim a wide variety of sheet metal, pipes, profiles, screws, and many other materials.

It can be used not only for cutting and separating, but also for surface finishing. By attaching a grinding or wire wheel, surfaces can be polished, sanded, or edges sharpened. The compact WALTER angle grinders and cut-off saws are electrically powered handheld tools whose attachments rotate at speeds of up to 12,000 revolutions per minute – guaranteeing maximum power!

Application areas

Angle grinders perform countless tasks around the home. DIY enthusiasts and home improvement makers primarily use WALTER angle grinders for cutting metal and wood, removing paint and rust, or smoothing and polishing welds and surfaces. Whether on the construction site, in the garden, or in your own car workshop, angle grinders are essential equipment!

How does an angle grinder work?

The angle grinder has a fairly simple design. It consists of a motor integrated into the housing, a matching gearbox, and the electronic control units. The gearbox then transmits the power produced by the motor to the disc via a drive shaft at a right angle. This causes the disc to rotate – in WALTER angle grinders, even at speeds of up to 12,000 rpm. At such speeds, even particularly hard materials like granite or stainless steel can be cut very effectively and quickly, depending on the disc used. The high speed is also particularly well-suited for polishing metals such as aluminum or iron.

Which size should I choose?

There are three common sizes: 115, 125, and 230 mm. This refers to the diameter of the disc. So, a 125 mm angle grinder can use a disc with a maximum diameter of 125 mm. Different sizes offer different advantages, but also disadvantages. For example, a 115 mm angle grinder is usually very small and handy, often due to its light weight, but unfortunately, most models lack the power to compete with larger tools.

The 125 mm angle grinder is perfect for DIY enthusiasts and professionals alike. It combines the best of both worlds: high speed and power, yet the compact dimensions of a smaller tool. It's exceptionally versatile, suitable for cutting sheet metal as well as precisely separating aggregates. The 230 mm angle grinder is particularly robust and powerful, but significantly heavier and larger than the other two sizes, which can quickly make work tiring. Its applications are best suited to large construction sites and particularly thick and hard materials.

What are the most important features?

The two most important criteria to consider when buying an angle grinder are the motor power and the maximum no-load speed. These indicate how much power the angle grinder can actually deliver. The higher the better.
However, attention should also be paid to certain safety features. For example, an ergonomically shaped or rubberized handle is significantly more comfortable and safer to use. It not only prevents slipping but also allows for longer use of the device, as it fits particularly well in the hand. Overload protection is also very helpful, as it not only ensures a longer lifespan but also reduces the risk of accidents and hazards.

Another advantage is a wide range of cutting widths. The thickness of the disc is crucial here. The wider the range, the more versatile the application. This allows for particularly thin cuts as well as wider cuts through solid materials. Note: Thicker discs wear down less quickly than thinner ones. Also, be sure to check that various accessories are available, such as a guard for cutting and one for scrubbing and polishing.

Separating or roughing?

The biggest advantage of an angle grinder? You can use it not only for cutting and sawing, but also easily convert it into a grinding wheel. Grinding wheels are made either of braided wire for coarse grinding work or of resins or corundum (or aluminum oxide). They are also significantly thicker compared to standard cutting wheels. Cutting wheels are often made of specially hardened metal and, depending on the application, may also contain diamond particles, giving them an even harder surface structure and making them less prone to wear. Ceramic-coated wheels are also commonly used, as they are particularly heat-resistant.

But beware: Cutting discs are only designed for straight cuts. Grinding along the side can lead to accidents and injuries!

How do you find the right disc for your project?

There are various discs available for different materials; the choice depends on what you intend to cut. Ideally, you should purchase a selection of different discs when you buy your machine, so you always have the right one on hand. However, you should still pay attention to the quantity and wear, as the discs have an expiration date. During manufacturing, various resins and other particles are incorporated into the disc, which can unfortunately age, compromising the disc's safety and cutting accuracy. Furthermore, you should pay attention to the maximum permissible speed of the disc. Most manufacturers use color coding for this, which is also clearly printed on the disc itself, along with the correct dimensions.

Always make sure to use the correct attachment:

• Cutting metal, stone, concrete, ceramic and wood – it's precise with diamond cutting discs!
• Sanding metal, stone, wood and more – sanding discs with sandpaper are suitable for this.
• Rust removal and cleaning work best with wire brushes.
• Planing and carving discs are used for woodworking.
• Polishing with wool discs and reduced speed – that ensures a shine!

Safety first!

Always wear work gloves, safety glasses, and ideally flame-retardant clothing when working with an angle grinder! Depending on the material, dust and sparks may be generated. Safety shoes are also highly recommended for body protection, as individual pieces often fall off when cutting workpieces.
