Web Machinist “ Smart Drill Index ”

View My Stats

The “Smart Drill Index” shown above is included in the “Web Machinist” Software Program below:

The Web Machinist Drill Index is now the Smart Drill Index!  What makes this drill index a Smart Drill Index?  Not only does this drill index chart provide the sizes of Fractional Drills, Number Drills, Letter Drills and Metric Drills in both inches and millimeters, it also can calculate the suggested speed and feed rates for common metal alloys!  See below:

The Smart Drill Index in Web Machinist allows you to reference the Drill Size and print each chart for reference.  If you click on any drill in any of the charts you will open the Drill Speeds and Feeds chart for that particular drill as seen below:

The Drill Speeds and Feeds chart provides calculated drill speeds and feed rates in both inches per revolution and inches per minute base on the drill size, metal alloy and metal condition.
