SPR Diamond
Uncoated
Economy grade grinding product for less demanding applications where abrasive cost is the primary consideration. The friability of SPR enables controlled diamond fracturing, wheel self-sharpening and free cutting action.

SPR N Diamond
Nickel based alloy coating
Coating level 56 wt %
Superior Diamond Innovations metal coating adds texture to the surface of the diamond, increases the crystal’s heat capacity and heat dissipation. Increased diamond retention and prolonged tool life are additional benefits.

SPR N 30 Diamond
Nickel based alloy coating
Coating level 30 wt %
Similar to SPR N, but with a 30 % coating level. Reduces grinding energy and heat generation, with a minimal reduction in wheel life.

SPR Cu50 Diamond
Copper coated
Coating level 50 wt %
Copper coating increases thermal conductivity of the wheel rim. Improved heat dissipation, prevents thermal workpiece damage in dry and wet grinding applications.
