Why do we need high powered grinders?

The obvious answer is that high powered grinders will save you money. 

• Higher power means you can remove more material or make more cuts per year.  Time is money right?
• Higher power also means that your abrasives will be working at their optimal speed, meaning you get a better finish and your abrasives will last longer.

Apart from this, abrasive manufacturers are coming up with more aggressive disks for faster material removal.  The problem with these new disks is that they will destroy most electric grinders and stall most air grinders because they need a high powered tool to run them.  Some examples are the PFERD ALU-Master, CC-Grind disks and the Maija Frästechnik milling discs. These unique new products offer extremely fast material removal but require high powered grinders.

The PFERD ALUMASTER high speed discs are a unique tool that offers very fast material removal.  It is ideal for use on aluminium because it does not produce hazardous or explosive dust. 

It uses ten replaceable tungsten inserts to machine the aluminium rather than grind it.  This also means that the tool doesn’t clog up.  

These discs suit 115mm or 125mm grinders with a max speed of 13,300rpm and PFERD recommend an air grinder of at least 1000watts or an electric grinder of at least 1400watts

Another new disc that requires a high powered grinder are the Maija Frästechnik milling discs.  These are available for a range of materials including steel, aluminium and titanium.  Maija Frästechnik tested and recommend Deprag Turbine powered grinders for use with their discs.

Cengar started business back in 1954 in Halifax, UK.  They patented the world's first twin piston air hacksaw in 1954, and then updated it in 1964.  Since then they have added new models and worked to improve the power, reliability and vibration levels of it's saws.  Recently Cengar updated it's production equipment to again improve quality and reduce lead times.

You will find Cenagr tools in oil rigs, refineries, fibreglass manufacturers, mines and pallet repair facilities all over the world.  They are used to cut steel plate, angle sections, I-beams, bolts, sections and pipes.  All of Cengars saws have very simple, reliable piston motors which use very little air.  No vanes, no bearings, no gears!  They are ATEX approved for T5, Zone 1 hazardous area use except for the Cengar JSM, which is ATEX certified to M2 for underground coal mine use.

Please beware, there are a number of copies of the Cengar CL50 and CL75. They are copies of the old version of these saws so they do not perform as well and they do not have ATEX approvals.  Spare parts are not compatible with modern Cengar saws, and it is an issue to find spares in Australia.

Assembly Technologies Pty Ltd are the Australian importers for Cengar saws.  We usually have all of the saws, blades and spares in stock.  Repair of the saws is very simple, any air tool repair shop should be able to repair them.  In case you have difficulty, we have a full work shop and are able to repair any Cengar saw.
