Weld gun cap dresser cutter

A tip dresser cutter, comprising:

• a circumferential portion having a circular shape rotatable about an axis of rotation;
• a center portion located radially inward from the circumferential portion proximate the axis of rotation;
• and
• a cutting flute extending radially between the center portion and the circumferential portion, the cutting flute comprising a leading edge, a trailing edge, a radially inward canted surface extending between the leading edge and the trailing edge,
• wherein the radially inward canted surface comprises:
• a first section extending between the center portion proximate the axis of rotation and a first location on the cutting flute;
• and
• a second section extending between the first location on the cutting flute and a second location on the cutting flute, the second section of the radially inward canted surface comprising a curved portion that is parallel to a plane of rotation of the cutting flute,
• wherein the second section of the radially inward canted surface further comprises a leading step portion located proximate the leading edge, and
• wherein the curved portion is recessed into the tip dresser cutter radially outward towards the circumferential portion relative to the leading step portion.

• wherein at least one of the following:
• (1) the second section of the radially inward canted surface further comprises a trailing step portion located proximate the trailing edge, and wherein the curved portion is recessed into the tip dresser cutter radially outward towards the circumferential portion relative to the trailing step portion;
• or
• (2) the curved portion encompasses a portion of the radially inward canted surface within the second section and not the entire radially inward canted surface within the second section, and wherein the second section of the radially inward canted surface further comprises:
• a second portion that excludes the curved portion, wherein at least one location in the second portion of the radially inward canted surface within the second section is located at a first distance away from the axis of rotation that is equivalent to a first radius, and wherein each location along the curved portion of the radially inward canted surface within the second section is located at a second distance away from the axis of rotation that is equivalent to a second radius that is greater than the first radius.
