PSA & MAGNETIC BACKED DIAMOND DISCS
NORTH JERSEY DIAMOND WHEEL carries an extensive line of diamond discs and polishing laps/pads. A wide variety of backs are available, from aluminum and solid steel backs, which are ground flat and parallel, to PSA (pressure sensitive adhesive) backs. Solid steel discs have a corrosion resistant copper undercoating to prevent rust. Discs are available with plain center holes, no center holes and with 1/4"-20 thread screw back mount. Many different types of diamond surfaces are available from uninterrupted surfaces to uniquely shaped working surfaces which aid in flushing away swarf. Discs come in a wide range of diamond grits from 60 for rough grinding to 3000 for polishing. In addition to the standard hard electroplated nickel process used for most discs NORTH JERSEY DIAMOND WHEEL also has sintered metal bond discs available. Discs range from 6" to 24" diameter.
