Drilling Speeds and Feeds The speed of a drill is measured in terms of the rate at which the outside or Finally, calculate the feed rate using Equation 3, given that the appropriate initial feed per tooth (chipload) is f t ≈ 0.008 in/tooth (from Table 3): f [in/min t × ×

The tool is designed so that holes up to the maximum depths can be produced in one step without chip removal, and this at the highest cutting speeds and feed rates. The through-coolant supply contributes to this and guarantees good cooling at the tip and hence outstanding tool life. Extra long drill with through-tool cooling CrazyDrill Cool XL

Speeds and feeds are based off of x3, x5, x7 drill lengths only utilizing flood coolant or coolant through where capable. Results *Recommended "Chimp" Loads *RPM SFM IPM IPR Cycle Time Per Hole (In Seconds) *The RPM and Chip Load that automatically populates in this calculator are the factory suggested parameters for running the desired tool.

A gun drill was used for deep hole drilling and we used etalon material, were here is possible to define cutting forces without any further 

Drilling Solutions Stub (2D - 3D) Short flute lengths and rigid. Ideal for shallow Holes. Jobber (4D - 7D) Medium to long flute length drills for a wide range of work materials. Taper (8D - 30D) Long flute lengths with stable chip evacuation for deep-hole drilling. Micro Drills under 2mm in diameter with length to diameter ratio’s up to 50XD

Selecting and using a gun drill for deep hole drilling can sometimes be the recommended speeds and feeds from the gun drill manufacturer
