We stock a range of 3M™ abrasives including aluminium oxide lapping film, aluminium oxide and silicon carbide micro fnishing films Our scary sharpening kits have been designed to provide the optimum mix of types and grades to enable clean, fast and efficient tool sharpening.
The films, approx A4 in size with a heavy duty Pressure Sensitive Adhesive, are cut into strips of the desired width, which are then attached to float glass or another perfectly flat substrate.
Aluminium Oxide Lapping Film has premium, micron-graded mineral particles that are electrostatically oriented for greater cutting efficiency bonded into a layer of resin that wears away slowly for increased durability.
Aluminium Oxide is a heavier duty version that lapping film - the particles are more pebble-like than silicon Carbide particles so they don't fracture as easily and last longer.
The Silicon carbide particles are longer, thinner, harder and more brittle than aluminium oxide, so they remove material very rapidly at first and then the finish becomes slightly finer as the abrasive 'beds in'.
3M abrasives are the preferred choice of industrial and professional users worldwide. Manufactured with astonishing precision and consistency using the best materials available they just work - beautifully!
