Re: [CAD_CAM_EDM_DRO] Carbide bits

Hi Roland:
      I watch for them on sell so I have a number of them when I get into something tough or hard.
They are not as good as a regular C5 carbide drill but they will cut better then a HSS bit in real hard
stuff.  Just be sure to grind them with a large angle on the end. Something like a 170 deg. tip angle
and don't back them off with a lot of clearance.  Recently used them to drill a hyd. cyl. rod and pin.
