What customers have to say about our work

“When I first e-mailed you I got a reply the next day advising me with what to purchase. You also went out of your way to get the grinder I required. You also went out of your way to have a normal conversation by e-mail. It looks like to me that you Paul care about small companies like me even though I live in NEW ZEALAND and also larger ones. Paul you are a credit to your company and may you go on to build it larger as you deserve it.”
Denis Roberts (Manager) New Zealand

"I feel I must tell you that I am over the moon with
the TV50 and C-tec cutting cowl. I used it for the first time today, and was amazed how well it
worked. It's worth its weight in gold. Thanks very much."
Regards Phil Hone.

Hi Paul,
Thank you for the lead.
Spoke to Rob, very happy with the two TV50’s which he purchased from you 10 years ago. We have now supplied him a new motor & head for one of the units the other is still going strong.
Best regards, Jerry”

 Bolt on Diamond Segments

Concrete - Grinding – Polishing

PWM bolt on diamond segments are available in a wide range of bonds and diamond grit size which have been designed to cover a wide range of applications. All segments are manufactured within the EU.

Our Standard range of diamond segments are suitable for a wide range of applications including removal of paint, general coatings, screeds and the cleaning and preparation of power floated floors.

Our PCD Segments are very aggressive and ideal for removal of adhesives, glue, thick coatings and latex - applications that standard diamond segments can struggle with.

Below is a brief description of each segment type and typical application.

Bond – The strength of the metal binder that holds the diamond grit in the segment. Typically the harder the bond the longer the life. An abrasive subfloor will require a harder bond. A harder floor will require a softer bond.

Grit – The size of the diamond grit in the segment. Typically the larger the grit the more aggressive the segment will be. The smaller the grit the finer the finish will be.  The higher the number then the finer the finish will be e.g. 3000 grit will give a highly polished finish.

Concrete – can be soft, hard, abrasive, dusty and brittle etc. No two floors are ever the same, typically they are more abrasive when new or have a high sharp sand content. The more abrasive the floor the harder bond you will need to get the best performance out of the diamonds.

DFG 5-3 Diamond Disc - Segment DFG 5-3 – Very Soft Bond 25 Grit Diamond - Aggressive silver segments with a soft bond combination making these segments ideal for very hard floors. The soft bond is designed to wear away on the hard materials so that new sharp diamond grit is constantly being exposed. Segment life is sacrificed to the benefit of increased output. Ideal for low powered grinders


DFG 7-4 Diamond Segment - Disc DFG 7-4 – Medium Bond 30/40 Grit - One of our most versatile segments suitable for a wide range of applications – a “general purpose” segment better suited to hard rather than soft concrete.  This segment type will give a finish suitable for a paint coating and is ideal for the removal of trowel marks and similar. A good balance of segment life V output that is effective over a wide range of surfaces.


DFG 7-5 Diamond Grinding Disc - Segment DFG 7-5 and 7-6 – Medium Bond 80 and 120 Grit – the first 2 stages of metal bond polishing. These bonds are an alternative to normal resin bonded polishing pads as they offer far better wear rates. Final polish with a resin pad in the equivalent grit size will still be needed.  Click Here for more info on our Polishing Pads.


DFG 8-4 diamond disc - segment DFG 8-4 – Hard Bond 30/40 grit – These segments offer a similar finish to the DFG7-4 but sacrifice a little output for better wear rates. Normally used on new or abrasive concrete, they have a stronger/harder bond which wears away slowly to expose the diamond grit. A long life segment!


DFG 9-4 Diamond Disc - Segment DFG 9-4 – Very Hard Bond 30/40 – These diamond segments have the hardest bond in our range while offering a similar finish to the DFG7-4 / 8-4 The ideal segment for very abrasive concrete. A very long life segment but some speed of output has been sacrificed.


DFG GT Diamond Disc - Segment DFG GT are for VERY VERY VERY! Hard concrete, for those jobs that just will not grind. Please ring for more information.


PCD Segments – Hard Bond, very large grit size, typically 8-10mm – These segments have been designed specifically for the removal of adhesives, thick coatings and latex.  Unlike standard segments the PCD segments have a scraping/cutting action that prevents smearing that can result from heat build up.

They are more resistant to accidental damage than the PCD Plate type segment. A high output, long life segment that easily justifies the higher investment.



Counter Clockwise PCD Plate

Counte Clockwise


PCD Plates, Clockwise and Counter Clockwise – These are a more aggressive type of PCD segment. They have been designed to work with the rotation of the machine, incorrect rotation will destroy them in seconds – you have been warned! PCD plates are ideal for removal of thick latex, coatings and adhesives.





“Grizzly” Diamond segments for the fast, effective removal of coatings, adhesive and bituminous materials. Available with our standard three screw fixing  for attachment to our full range of grinders or for direct fitting to specific drive plates.
