M14 Diamond Grinding Turbo Cupwheels. 36 grit

Description   : Aluminum cup wheels are better because the body of aluminum does not conduct (retain heat) unlike steel cup wheels.

Steel is a conductor of heat.,The friction caused by grinding stone creates a build up of heat and after 30minutes or so there can be a high temperature  build up on the disc. , resulting in burnt fingers and destroying  all the diamonds, making the cup wheels less effective. Heat creates burn marks in the alloys and pit holes of gas in the metal body. resulting in breaking up the segment on the disc. (Destroyed disc)

Aluminum cup wheels are better because they are balance perfectly. Each  disc or wheel is laithed out of a single block of aluminum and  centre threaded with M14 to fit all UK market grinders. 

The Segment is molecular bonded to the surface of aluminum. The segment is moulded in our factory and stamped with the turbo pattern which is very rough to take off lots of material. The mould is imprinted   to only a depth of 6mm with a 3mm solid smoothing section to the  bottom. Masons find this an advantage. They use a worn cup wheel  disc to do fine finishing (removing saw marks from blades) They  state there is no need for higher grits. One tool for the job. In fact the man featured on our video (25 years experience) on our web site says "I have 2 cup wheels on the go. one to shape.  when it 's worn past the turbo ridges, I use it to polish off. or to fine tune what I am doing. I find them good on lots of types of stone.(sandstone- hard & soft ) They don't burn my fingers when I want to change them over.
