ROTATING APPLICATIONS
Inch Drill Bodies with a Round Shank
DRILL-FIX DFR inch drills with round shanks (no flats) are specifically designed for use in rotating applications where the drill rotates and the workpiece remains
stationary.
Metric Bodies with 2° Whistle Notch
DRILL-FIX DIFT and DFR inch drills with a flange can be used in rotating applications where the drill rotates and the workpiece remains stationary. To maintain accuracy and get maximum performance from the drill, use only the approved toolholding method shown below.
Inch Bodies with Flange
DRILL-FIX inch drills, with a flange, were designed for use on lathes or any machine where the tool remains stationary and the workpiece rotates. An “x” is marked on the flat of the X-axis of the drill to aid insert orientation on the machine tool. It is important to align the X-axis of the drill with the X-axis on the machine tool. Accurate alignment is absolutely essential for good performance. The drill must be on center, within the tolerance shown above. Angularity must not exceed .003 within the designated drill depth.
