Speeds and Feeds calculator A drilling speeds and feeds calculator is vital if you want to drill metal efficiently. Due to the fact that different metals heat up faster than others you will see that recommended drilling speeds vary. For example you will see the drilling speed for stainless steel is lower than many other metals.

The RPM calculated in the Drilling Speed and Feed Calculator refers to the spindle speed in drilling process, and the IPM refers to feed rate. The exact RPM is not always needed, the following calculator (formula) may be used to estimate the value closely. Cutting speed (SFM): the rate at the workpiece surface, measured in surface feet per

Star Single Flute Gundrill Used as a general-purpose tool in most drilling applications to obtain hole sized within .001", run-out requirements of .001" per inch, straightness of .001" per foot. This tool has a single fl ute, 3-piece construction design and has the deepest fl ute channel, enabling maximum chip evacuation.

To calculate the feed rate, use the following formula: f = N × fr. (Eq. 3) where f = calculated linear feed rate of the drill [in/min]. N = spindle speed
