Patent ID: 7373935

Claim:
A carbide wire blade comprising: a. a solid cylindrical metallic body comprising a first end, a second end, and an outer surface having an outer diameter, OD 1 ; b. a first tungsten carbide cutter slideably mounted on the body and comprising a central longitudinal channel extending the entire length of the first cutter and having an inner diameter, ID 1 , sized to slideably fit over the body, said first cutter further comprising a distal end region comprising a cutting lip having an outer diameter, OD 2 , and a proximal end region having an outer diameter, 0 D 3 , that is less than OD 2 , such that the outer surface of the first cutter forms an angle with respect to the outer surface of the body in the range of 1° to 45°; c. a first vibration dampening member slideably mounted on the body and positioned adjacent the proximal end of the first cutter and having an inner diameter, ID 2 , substantially equivalent to ID 1 , and an outer diameter, OD 4 , that is greater than ID 2 and less than or equal to OD 3 ; and d. a first spacer slideably mounted on the body and comprising a distal end adjacent the first dampening member, said distal end comprising at least one slot, and a proximal end opposite the distal end, said proximal end comprising at least one slot, said spacer comprising a central longitudinal passageway extending the entire length of the spacer and having an inner diameter, ID 3 , sized to slideably fit over the body, said first spacer having a length in the range of ⅛ to ⅝ inches.
