wherein the tip end at least two walls and at least two additional walls define key blank carrier front and back sides and key blank carrier bit and spine sides respectively, the key blank carrier front side comprising at least one aperture extending through the key blank carrier front side along an edge of the front side bordering the key blank carrier spine side.
7. The key blank cutting carrier of claim 6 , wherein the at least one aperture extending through the key blank carrier front side comprises at least two apertures extending through the key blank carrier front side along the edge of the front side bordering the key blank carrier spine side.
8. The key blank cutting carrier of claim 1 ,
wherein the carrier body comprises an elongated sleeve defining at least a portion of the key blank recess,
wherein the sleeve further comprises a tip end and a head end, the head end comprising a substantially planar surface, the tip end being at least partly formed by the at least two walls and at least two additional walls, and
wherein the tip end at least two walls and at least two additional walls define key blank carrier front and back sides and key blank carrier bit and spine sides respectively, the key blank carrier front side comprising at least one aperture extending through the key blank carrier front side along an edge of the front side on the key blank carrier bit side.
9. The key blank cutting carrier of claim 1 , further comprising a key blank positioned within the recess in direct contact with the at least two walls.
10. The key blank cutting carrier of claim 1 ,
wherein the carrier body comprises an elongated sleeve defining at least a portion of the key blank recess,
wherein the sleeve further comprises a tip end and a head end, the head end comprising a substantially planar surface, the tip end being at least partly formed by the at least two walls and at least two additional walls,
wherein the tip end at least two walls and at least two additional walls define key blank carrier front and back sides and key blank carrier bit and spine sides respectively, the key blank carrier front side comprising at least one aperture extending through the key blank carrier front side along an edge of the front side on the key blank carrier bit side, the key blank carrier bit side further comprising a shoulder band adjacent to the head end between the head end and the at least one aperture, the shoulder band extending from the front side of the key blank carrier to the back side of the key blank carrier.
11. A key blank cutting carrier adapted for mechanical interface with a key blank cutter, the carrier comprising:
a key blank carrier body;
a key blank recess within the key blank carrier body, the recess defined by at least two walls and sized and shaped to securely receive at least a portion of a key blank within the recess;
at least one key blank cutter alignment feature coupled to the carrier body and positioned on the carrier body to mechanically engage a portion of a key blank cutter into which a portion of the key blank carrier is placed; and
a key blank burr removal opening in a first edge of the carrier body, wherein the key blank burr removal opening comprises a beveled edge.
12. The key blank cutting carrier of claim 11 , wherein the key blank burr removal opening is a V-shaped opening.
13. The key blank cutting carrier of claim 11 , wherein the key blank carrier body further comprises a substantially planar surface, and the first edge of the carrier body forms a first edge of the substantially planar surface.
14. The key blank cutting carrier of claim 11 ,
wherein the carrier body comprises an elongated sleeve defining at least a portion of the key blank recess,
wherein the sleeve further comprises a tip end and a head end, the head end comprising a substantially planar surface, the tip end being at least partly formed by the at least two walls and at least two additional walls,
wherein the tip end at least two walls and at least two additional walls define key blank carrier front and back sides and key blank carrier bit and spine sides respectively, the key blank carrier front side comprising at least one aperture extending through the key blank carrier front side along an edge of the front side bordering the key blank carrier spine side.
