A gear cutting tool of the type formed from a length of bar stock having a generally rectangular cross-section comprising a first cutting face formed into a front wall portion of the bar stock at a desired rake angle therewith for a part of the length of said cutting tool, said tool including a base portion having rectangular mounting surfaces extending the remaining length of said cutting tool and a cutting end having a first flank surface formed thereon for defining a first cutting edge between said first cutting face and a first side of the tool, and further comprising a second cutting face formed as a slot in said front wall portion of the bar stock at a desired rake angle therewith for substantially the full length of said cutting tool, said cutting end also having a second flank surface formed thereon for defining a second cutting edge between said second cutting face and a second side of the tool.
A method for manufacturing a gear cutting tool of the type formed from a length of bar stock having a generally rectangular cross-section comprising the steps of:
- forming a first cutting face in a front wall portion of the bar stock at a desired rake angle therewith for part of the length of the tool;
- forming a second cutting face as a slot within said front wall portion of the bar stock at a second desired rake angle therewith for substantially the full length of said cutting tool;
- forming a cutting end having first and second flank surfaces thereon for defining first and second cutting edges between said cutting faces and sides of the tool.
