摘要： PROBLEM TO BE SOLVED: To provide a tooth profile of cutting tools that can offer such a path of chips as reduces the abrasion of edges near tool corners. SOLUTION: This metal cutting tool in form of, for example, a saw blade and a grooving tool, has teeth each having a major cutting edge 14 and side cutting edges. Each major cutting edge 14 is rounded on a large radius via a polishing process, and each side cutting edge has a radius made smaller by flat-grinding of at least a part 23 of its related side face after the rounding by the polishing process.

摘要： A metal cutting bandsaw blade includes a strip and a recurring group of teeth projecting therefrom. The recurring group of teeth has a setting pattern and a height pattern. The setting pattern has at least three units selected from the following setting types:(a) unset teeth(b) teeth set to the right(c) teeth set to the left.The setting pattern includes at least one of each of the setting types. The height pattern has at least two selected from the following height types:(a) high teeth(b) low teeth.The height pattern includes at least one of each of the height types. The total number of teeth in the recurring group is the product of the number of setting units and the number of heights units. The number of setting units is incommensurable with the number of height units. The number of teeth set to the right in the recurring group is equal to the number of teeth set to the left. All of the set teeth in the group have substantially equal setting widths.

摘要： Bandsaw blade with teeth arranged in recurrent groups, where each tooth has a height either high, medium or low, and a setting either right, left or unset, and the group is formed by having tooth height variations in subgroups with a first number of members, and setting variations in subgroups with a second number of members, where the first and second numbers are incommensurable, making the number of teeth in the recurrent group equal to the product of the first and the second numbers, and where all set teeth have the same setting width regardless of height. One example is where tooth height varies in subgroups of two and setting in subgroups of three, making the number of teeth in the recurrent group equal to six. Another example is with three teeth in the height group and four in the setting group, making the number of teeth in the recurrent group equal to twelve.
