Embodiment Construction

[0018] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In some cases, reference numerals will be indicated in this specification and the drawings will show the reference numerals followed by letters such as 100a, 100b or primary designators such as 100', 100", etc. It should be understood that in the drawings Letters or main designators are used immediately after the designation to indicate that these features have a similar shape and have a similar function as is usually the case when the geometric structure is mirrored about the plane of symmetry. For ease of explanation in this specification, the letters or main designators are generally not Included herein, but may be shown in the drawings to indicate repetition of features discussed in this written description.

Abstract

A tool bit (200, 300, 400, 500) comprises a shank portion (202, 302, 402, 502) including a cylindrical configuration defining a longitudinal axis (L), a radial direction (R), and a circumferential direction (C), and a working portion (204, 304, 404, 504) including a cylindrical configuration that is concentric with the shank portion (202, 302, 402, 502) and a flat bottom surface (218, 318, 418, 518).

Description

technical field [0001] The present invention relates to cast serrated cutting edges formed from replaceable drill bits for motor graders or other similar equipment. More specifically, the present invention relates to a low cost cutter head that attaches to a blade assembly of a machine. Background technique [0002] Machinery such as motor graders use long blades that are used to level the work surface during the grading phase of construction work, etc. These blades often encounter abrasive materials, such as rocks, dirt, etc., which can degrade the working edge, rendering the blades ineffective for their intended purpose. Some blades have a serrated cutting edge, which means that instead of being continuously flat, the edge undulates up and down, creating teeth. The downside of this blade is that the teeth may wear out more easily than desired. After 100-200 hours of operation in a harsh environment, such blades can be dulled while substantially removing the teeth. They...
