60° inclusive countersinks drill downwards a small amount in order to make a quality starting hole and a profile. Follow up with a secondary drill for the full depth of cut of the workpiece. They don't route along a slot. Combination drill/countersinks provides exceptional starting positioning for secondary drills, PLUS provide qualified countersink dimensions for screw heads, etc. Premium Aluminum Titanium Nitride (AlTiN) coating provides quantum increases in productivity, either in terms of speed or longevity, with or without coolant.
Use on manual or CNC driven lathes and manual or CNC driven milling machines.
Excellent for cutting:
Poly (methyl methacrylate) (PMMA)
*Cermets are composites in which ceramic materials and metals join together.
**Coroplast® is soft plastic cardboard made with super soft, super flexible PVC.
AlTiN Coating Benefits:
Extra wear resistance
Allows for faster feed and speed rates
Cutting edge protected from wear
Better chip evacuation
Less heat build up
Superior cutting quality and extended tool life
WARNING! Inspect cut quality and adjust feed and speed accordingly. Care should be taken to observe proper feeds and speeds according to the workpiece material to avoid damage.Note: For optimal results and extended tool life use mist lubricant system or air cooling.
