Benefits of technology
The invention is a rotatable cutting tool for use in impinging earth strata. The tool has a cutting tool body with a head portion, a collar portion, and a shank portion. The head portion has a first head section and a second head section, each with a plurality of side faces that meet to form common edges. The first head section has a first angle relative to the central longitudinal axis of the cutting tool body, and the second head section has a different angle. The technical effect of this design is that the tool can efficiently cut through earth strata with high precision.
Problems solved by technology
As can be appreciated, during operation the entire rotatable cutting tool is typically subjected to a variety of extreme cutting forces and stresses in an abrasive and erosive environment.

Embodiment Construction
[0013]Referring to FIGS. 1-2, there is illustrated a cutting tool, generally designated as reference number 10, in accordance with aspects of the invention. It will be appreciated that the invention has application to various kinds of cutting tools useful in various kinds of cutting operations. Exemplary operations include, without limitation, road planing (or milling), coal mining, concrete cutting, and other kinds of cutting operations wherein a cutting bit with a hard cutting member impinges against a substrate (e.g., earth strata, pavement, asphaltic highway material, concrete, and the like) breaking the substrate into pieces of a variety of sizes including larger-size pieces or chunks and smaller-sized pieces including dust-like particles. In addition, it will be appreciated that the cutting tool 10 of the invention may be manufactured in various sizes and dimensions depending upon the desired application of the tool.

Abstract
A rotatable cutting tool for use in impinging earth strata includes a cutting tool body having a central longitudinal axis, the cutting tool body including a head portion, a shank portion axially rearward of the head portion and a hard cutting tip affixed to the head portion of the cutting tool body. The head portion includes a first head section adjacent to an axial forward end of the head portion, wherein the first head section includes a plurality of first side faces such that adjacent first side faces meet to form a corresponding plurality of first common edges. The head portion further includes a second head section adjacent to an axial rearward end of the head portion, the second head section having a plurality of second side faces wherein adjacent second side faces meet to form a corresponding plurality of second common edges.
Description
BACKGROUND OF THE INVENTION[0001]The invention pertains to a rotatable cutting tool that is useful for the impingement of earth strata such as, for example, asphaltic roadway material, coal deposits, mineral formations and the like. More specifically, the present invention pertains to a rotatable cutting tool that is useful for the impingement of earth strata wherein the cutting tool body possesses improved design so as to provide for improved performance characteristics for the rotatable cutting tool.[0002]Rotatable cutting tools have been used to impinge earth strata such as, for example, asphaltic roadway material or ore bearing or coal bearing earth formations or the like. Generally speaking, these kinds of rotatable cutting tools have an elongate cutting tool body (typically made from steel) and a hard tip (or insert) affixed to the cutting tool body at the axial forward end thereof. The hard tip is typically made from a hard material such as, for example, cemented (cobalt) tun...
