*Tapping Recommendations:  Drill Sizes should be 2% - 3% larger than standard in HT, AT, and Hard Alloys.
*For Automatic Tapping RMP should be 10x TPI.
*Reccomend Taps for Pre-Heat Treated Alloys up to 38 HRc.
*All Feeds & Speeds are based on the use of Carbide tooling.
*Actual optimum Feed & Speed will vary upon machine rigidity, horsepower, coolant, tool geometry, etc.
