Abstract
Official abstract text for this publication.
A tool bit includes a hexagonal drive portion, a working end, and a shank interconnecting the drive portion and the working end. The shank includes an outer peripheral surface having a curvature in a plane including a central axis of the tool bit. The outer peripheral surface having the curvature includes a length in the direction of the central axis. A ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.15:1 and about 0.35:1. The curvature is defined by a radius, and wherein a ratio of the radius of the curvature of the outer peripheral surface of the shank to the length of the tool bit is between about 0.08:1 and about 0.75:1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tool bit comprising: a hexagonal drive portion; a working end; and a shank interconnecting the drive portion and the working end, wherein the shank includes an outer peripheral surface having a curvature in a plane including a central axis of the tool bit, wherein the outer peripheral surface having the curvature includes a length in the direction of the central axis; wherein a ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.15:1 and about 0.35:1; wherein the curvature is defined by a radius, and wherein a ratio of the radius of the curvature of the outer peripheral surface of the shank to the length of the tool bit is between about 0.08:1 and about 0.75:1. 2. The tool bit of claim 1 , further comprising an identification band received within a groove of the shank, wherein the identification band is positioned between the curvature and the hexagonal drive portion in the direction of the central axis. 3. The tool bit of claim 1 , wherein the length of the outer peripheral surface having the curvature is between about 0.15 inches and about 0.35 inches. 4. The tool bit of claim 1 , wherein the radius of the curvature is between about 0.08 inches and about 0.75 inches. 5. The tool bit of claim 1 , wherein the shank is polished to a surface finish of at least about 2 microns along the entire length of the outer peripheral surface having the curvature. 6. The tool bit of claim 1 , wherein the hexagonal drive portion and the working end each include a corrosion-resistant coating. 7. The tool bit of claim 1 , wherein the tool bit includes a hardness between about 52 HRC and about 60 HRC.
