High-power angle grinder with the ability to install discs up to 125 mm in diameter. It is distinguished by high productivity, the user can easily perform both cutting and grinding work. Adjusting the speed allows you to adjust the angle grinder to the mode that suits the operator.

A feature of the grinder is the handle, which can be fixed in two positions on the left or right, making it more convenient to use. The spindle lock also makes the unit especially attractive, making it easier to change the equipment.

Convenient and inexpensive angle grinder with a disc diameter of 125 mm and the ability to adjust the rotational speed. Despite its very small size, it impresses with its power (900 W). The tool is quick and easy to handle the task at hand, whether sanding or cutting materials.

The ergonomic handle ensures safe working with the grinder. The discs can be easily removed and, conversely, fixed on the unit. It provides speed control. The tool does not overheat. The cord is 2.5 meters long.

  • Convenient to operate.

Two-handed small angle grinders.

Despite the name, even one-handed grinders, in which the body is used for the main grip, are equipped with an additional removable handle screwed into two or three fixation points on the gearbox.
Titan PSUM11125E, Proton MSHU-125/1150 Semi-Pro are equipped with more powerful electric motors, for which it was necessary to increase and lengthen the case. With them, the second hand is no longer used to clamp the workpiece. Such a tool is held with both hands, but due to a reliable grip, it has become easier to control the position and wiring of the equipment. Cooling is also improved, as on the one-handed vents are partially covered by the palm.

Grinder 125mm Sturm AG9012TE with speed control. Large grinder 230 mm Sturm AG9527P. Large grinders.

Inconvenient for making precise cuts, for example, cutting pores in welds of thin-walled pipelines. The 6.7 kg weight, like the GA9040RF01, is more difficult to control for the accuracy of the immersion depth. The cutting discs of large angle grinders start from 2 mm thick, as opposed to 0.8 mm for small 125 models.
Even a physically strong worker can hardly cope with the force of a jerk, when the rig is jammed. But a cutting depth of up to 85 mm, in one immersion without turning the workpiece, can only be performed by large grinders, such as DWT WS22-230 D or Titan BSUM20230. Cutting through is more hindered by the dimensions of the case. You can also go a little deeper by tilting the angle grinder, but the cut will no longer be perpendicular to the surface.

Titan PPMK11 Water Fired Stone Polisher. Professional. Angle grinder 180 mm Titan BUSM12-180. Why isn’t the lower limit lowered to the minimum?

The variable speed angle grinder gives you more options for grinding and polishing, but not cutting. Deep scratches are not removed at high speeds. The fur coat or foam pad attached to the rubber support-sole will be torn off, the rubber platform will start to smoke, the polish will fly off the rig. Traces of burning will remain on the wooden blank, and the plastic will soften and melt.
The impact with felt, foam rubber, wool, sisal or polymer-abrasive wheel is performed at low, but different speeds and the wider the speed range on the grinder, the more possibilities for processing.

However, the cooling system of the LBM electric motor depends on its rotation and at low speed the motor, especially under high load, quickly overheats.
In professional models of most manufacturers: AEG WS12-125 XE, Makita 9562CRV, Flex LE 14-11 125, the lower limit is 2800 rpm. On a household tool, you can find 1000 rpm, like the Titan PSUM11125E. The operation of such grinders requires more attention from the user and periodic switching on at maximum idle speed to increase the flow of cooling air.

Small one-handed grinder 125mm Titan BSUM7125. One-handed models.

Professional, such as Makita GA5030 or AEG WS10-125, household, such as BauMaster AG-90122X or Dnipro-M MShK-980 differ from other tools. They have a short body: 250-280 mm; light weight: 1.5-2 kg; electric motor power: from 700 to 1000 watts, and girth: 175-190 mm.
The small diameter of the main handle, only 55-60 mm, with a taper at the end, makes it possible to hold the small 125 mm single-handed grinder even for a worker with a medium palm and short fingers.

A strong grip is reinforced with ribs on the non-slip plastic of the body, like in Einhell TE-AG 125/750, or with rubber pads, like in Vitals-Master Ls 1272HL.
To turn on without the help and interception with the second hand, the wide Start key is installed on the side and slider type, like in Stanley STGS9125. It does not need to be groped, it is always in the area of ​​the thumb and due to this the angle grinder is controlled even with a glove. To increase passive safety on small one-handed grinders, keys are installed with a shift force above average, like in Dnipro-M MShK-800.

This tool is useful for short cuts and localized grinding. For example, in a confined space under the bottom of a car, in the engine compartment, in an overhead position or standing on a ladder when the worker can hardly reach the object even with an outstretched hand.
Working with wire brushes with one hand is inconvenient because heavy rigs have a higher moment of inertia and skid.
