Diamond Gravers are
non-rotating tools intended for scratch engraving of trophy brass and aluminum.
They are available with tip angles between 90° and
150°. The material being engraved determines the angle of cutter to use. The
softer the material, the wider the angle needed. If the
angle is too sharp (lower number), the graver may dig in and cause a
rough cut. Also, the pressure must be adjusted to suit the
particular material being engraved.
