The KIK® HS Brad Point Bit can be sharpened with a Flat File simply by following the shape and angle of the
cutting edges at the tip of the bit.
With a Grinding Wheel, place the bit with one wing and the spur point engaging the edge of the wheel.
Rotate it horizontally to 15º (45º Center) from the centerline of the wheel (Fig 1).
Then tilt the bit 10º (45º Center) above that centerline (Fig 2). Repeat for the other side of the bit.
