No other sanding tool can be used so universally.

No matter what the concern, the bench grinding machine PBGS 10‑120 with working speeds adjustable from 0 to 11,500 rpm masters all the following tasks and more:

Sharpening tools that have become blunt, such as drill bits, milling cutters, cutting blades, scissors or knife blades on the preassembled grinding wheel (grain size 120). Polishing surfaces on the preassembled polishing disc (grain size 400). Grounding wooden or plastic workpieces or engraving glass, ceramics and leather by means of the flexible shaft with ball bearings and the matching rotation tool. Even cutting operations and removing rust spots are effortless with the high-speed drive shaft.

Fields of application for the bench grinding machine PBGS 10‑120:

  • Polishing
  • Sanding
  • Sharpening
  • Deburring
  • Rust removal
  • Engraving
  • Cutting
  • Milling

Safe working with secure positioning

Laterally closed guards and two swivel-mounted protective screens in front of the grinding stones always ensure safe working without flying sparks. The workpiece supports can be conveniently adjusted to the respective application or workpiece by means of a knurled screw. For a non-slip and low-vibration stand, four rubber feet are integrated into the solid base of the device. In order to firmly screw the bench grinding machine PBGS 10‑120 to a workbench or work table, a bottom plate with pre-drilled holes is already attached to the device. It is also possible to temporarily fix the machine to a vice or on a frame to use the bench grinder as a pedestal unit. A safe stand with minimum vibration development of the machine should always be ensured.

282-piece accessory kit

Accessories tip for the PBGS 10-120:
Maximum radius of action with the 282-piece accessory kit for rotation tools

You'll be perfectly equipped if you directly get the maxi accessory kit with 282 pieces for the Trotec bench grinding machine PBGS 10‑120, which universally matches conventional rotation tools. In this way you'll not only be provided with a well-assorted supply of spare tools at home, but, thanks to a variety of further accessories you'll also benefit from a great deal of additional options. You're for instance provided with additional silicon carbide grinding stones for processing porcelain, glass or ceramic, polishing and cleaning brushes of brush bristles, brass and stainless steel for material-compliant applications, a large diamond-tipped milling cutter set, different engraving cutters and lots more.    

The 100-piece accessory kit in detail

The 100-piece accessory kit of the bench grinding machine PBGS 10‑120 always offers you the right tool for countless application possibilities.
In the following we'll describe the individual attachments and accessory parts sorted by possible applications:

Cutting / separating

12 x Cutting wheels
With the stable cutting wheels made of fibreglass-reinforced material, thin wood, sheet metal or plastics can be cut with precision. Also thin, protruding screws or nails can be cut off.

Grinding / sharpening

40 x Grinding wheels
The abrasive wheels are made of an especially resilient material. They are perfectly suited to carry out woodwork or for grinding metal or plastics.

10 x Abrasive belts
With the abrasive belts different materials like hardwood and softwood, metal and fibreglass can be reliably processed even in the smallest space – e.g. also for smoothing edges that are rounded from the inside and outside. The abrasive belt is simply attached to the corresponding abrasive belt mandrel (included in the kit).

10 x grinding heads (corundum/aluminium oxide)
The high-quality grinding attachments made of corundum or aluminium oxide offer high resilience with regard to hard material. They are ideal for grinding, sharpening, smoothing and deburring stone, ceramics or different metals.

1 x Grinding stone
The rectangular grinding stone made of corundum serves to sharpen the blade or to deburr tiles-, glass- or ceramic edges.

Polishing / cleaning

10 x felt polishing attachments
With the polishing heads of felt you can clean most metals as well as wood, stone, tiles, ceramic, glass, marble, granite and plastics without any problems. Dust is reliably removed even from the smallest gaps and old, tarnished jewellery, for instance, shines with a new brilliance. 

1 x Polishing paste
For polishing metal and plastic surfaces with felt or textile attachments to a high finish, we recommend using the polishing paste. It removes the oxidation film and can get rid off small defects on the surface.

3 x brass brush
The brass wire brushes are softer for cleaning than stainless steel brushes and treat the surfaces of soft metals such as gold, copper or brass with care – apart from jewellery and accessories, these also include door handles, specific vehicle parts and electrical contacts.

4 x cleaning brushes
The different cleaning heads clean particularly efficiently and in poorly accessible intermediate spaces.

Milling and engraving

3 x milling cutter / 2 x diamond-tipped engravers
The carbon steel milling cutters with a straight groove thread, ball head and bevel are suited for steady grooving or milling out as well as making recesses and indentations. The 2 diamond-tipped engraving bits for rougher to very filigree engraving tasks are included. The engraving bits can be used for materials of wood, ceramics, glass, metal, leather as well as further materials.

Mandrels and bits for ideal stability

2 x mandrels for abrasive belts
The mandrels are used to hold the abrasive belts.

2 x mandrels for cutting/sanding discs, polishing felt
The mandrels serve to insert the polishing bits of felt and textiles as well as the cutting wheels and abrasive wheels.

3 x collet chucks
For the use of further tool bits, 3 collet chucks are included in the kit.

1 x Wrench
To provide for a quick change-over of the tool bits, a universal wrench for commercially available multi-function tools is already enclosed.

Flexible shaft, storage box

1 x flexible shaft, 1 metre (attachment)
A practical flexible shaft is included to also make filigree work that requires a great deal of finesse an easy task for you. In this way you can guide the tool point one-handed like a pen.

1 x Storage box
With the practical wooden storage box you always have all tool heads and accessory components handy and smartly stowed away.

Brand quality plus cost-efficiency

So far, you basically only had two options when choosing a bench grinder: either good but expensive, or mainly cheap.

Trotec's PowerTools now offer a smart choice: good and cheap at the same time. For we do not only stand for brand quality where measuring devices and air conditioners are concerned, but also when it comes to power tools: professional Trotec solutions with an excellent value-for-money ratio!

Tips and notes for selecting the correct speed level

  • For cutting, forming, chamfering or milling grooves in the wood, and for sanding or grinding wood or metal, select a high speed.
  • If you wish to cut plastics or other materials with a low melting point, select a low speed.
  • For drilling into wood, select a low speed to prevent overheating of the tool.
  • For polishing, buffing and cleaning by means of a wire brush, select the lowest speed in order to prevent damage of the brush by loosening of the bristles from the mount.
  • For milling or drilling into non-ferrous metals, such as aluminium, copper, lead, zinc alloys, select a low speed. Additionally use a cutting oil or another suitable lubricant (not water) in order to prevent chips from settling on the cutting edges of the tool, and to prevent the tool from being overheated.

Info: Even with lower speed values, you should work without pressure. Applying higher pressure to the workpiece will not improve the result.
Alternatively, for example, use a different tool bit or another speed setting to obtain the desired result.
