Helically Interpolating a Hole at 225 IPM Through a Milled Slot
with Toroid End Mill and RHINO-CARB™ Inserts from Dapra
 
This video demonstrates Dapra's 1" Toroid End Mill executing the helical interpolation of a 1.75" diameter hole to a depth of 1.25".  The material is H13, and the machine tool used is a Fadal 4020 with a 40-taper spindle. 
 
Hole making with helical interpolation provides fast metal removal without significant spindle load or stress on the machine tool. It also allows for hole making to begin on a less than ideal surface, as the video demonstrates. In this case, the top 1/2" of the hole is made through an existing slot, a function not possible with a drill. Additionally, helical interpolation allows many hole sizes to be achieved with one tool, also not possible with a drill.
 
The parameters for this video are:
