    You can buy an angle grinder for very little money so why would you buy a variable speed grinder? With it’s versatility, range of accessories and solid reliability the Finipower + variable speed angle grinder is the machine of choice for grinding, finishing and polishing.  Stainless steel, non ferrous metal, it does everything. So why, how and when should you use the Finipower variable speed grinders?

    Why Does Speed Control Matter?

    Consider using a cutting tool.  When drilling different metals it is standard practice to change the drill speed to ensure effective use of the drill.  Abrasives are no different. If you want the right performance and optimum lifetime from your abrasive when working on stainless steel and non ferrous metals then you need to be able to vary your machine speed. Most abrasive manufacturers will put the maximum safe operating speed on a disc, what you need to know is the recommended operating speed. Recommended operating speeds are often half the maximum. But operating at the recommended speed is no use if the machine has no torque.

    The Finipower variable speed angle grinders allows you to control the speed.  Reducing the grinder speed will

    • Reduce the grinding temperature which will also reduce the risk of work hardening the metal
    • Significantly improve the life of your abrasives and therefore reduce your costs
    • Improve control and therefore reduce Re-working and
    • Give a better quality finish thus increasing customer satisfaction 

    They are versatile machines which can be used for grinding, satin finishing and mirror polishing various materials with a range of attachments.

    So What Can Attach to the Finipower?

    The Finipower variable speed grinders have an M14 2.0 pitch thread. So the short answer is, ‘almost anything’.  With a range of different fittings you can cut, grind, finish and polish with your Finipower.

    Note: We recommend a maximum wheel width of 50mm for sanding and finishing wheels and brushes. User a wheel wider than 50mm can damage the gear head and bearings.

    • Tapered spindle (Part no:  MH/T1) – Fitting a tapered spindle allows the operator to work with polishing mops, lap mops and unitised wheels for  polishing, weld discolouration removal and finishing.  To prevent damage to the gear head we specify a maximum recommended width 25mm and a maximum recommended diameter 150mm.
    • Spindle extension attachment (Part numbers:  MH/D1, MH/D2 + MH/D3).  With an M14 spindle extension attachment any abrasive wheel or brush up to a maximum 50mm diameter can be fitted onto a parallel shaft including unitised wheels, cloth abrasive flap brushes and a range of other tools.
    • Brushes and wheels fitted directly onto the M14 thread.  Cibo have developed an extensive range of wheels and brushes manufactured to include an M14 fitting so they can be spin directly onto the grinder thread.  Maximum available width 50mm.

    There are three different options, all of which screw directly onto the Finipower:

    Hints and Tips

    1. Recommended operational speeds for your Finipower:

    • High power grinding including with coarse flap discs – 6,000 rpm
    • Medium aggression sanding such as traditional sanding discs and Rapid Combi Discs – 3,500 to 5,000 rpm
    • Finishing and pre-polishing – 3,000 to 4,000 rpm
    • Wheels & brushes – 2,000 to 3,000 rpm

    2. To prevent any shaft fixed onto the grinder from binding to the metal face of the grinder shaft we recommend that whenever possible you keep the disc backing flange on the machine when attaching any mandrels or other wheels.

    n.b.  Appropriate PPE and other safety wear should be used at all times.
