INDEXABLE DRILL TROUBLESHOOTING TIPS:
Inserts Chipping or Breaking-
  • Inadequate coolant supply- Check coolant volume and pressure
  • Speeds and feeds being used are incorrect- Adjust speed and feeds according to tables provided
  • Insert screws may be damaged- Check screw head and thread for nicks and burrs. Do not overtighten screws
  • Inserts not seating properly- Make sure the inserts are seated properly in the pocket bottoms. Clean insert pockets whenever inserts are replaced or indexed making sure no nicks or burrs are present.
  • Misaligned drill/offcenter drill- Check toolholder TIR. Replace or adjust TIR as necessary.
  • Drill not seating properly in tool holder, spindle or turret- Make sure there are no nicks, burrs or chips in tool shank and/or holder. Use a feeler gauge to check parting line between tool shank and socket.
  • Too much tool deflection or lack of tool rigidity due to too much tool overhang- Check if tool can be held shorter.
Rough Cutting Action-Tool Makes Rumbling Noise and Deflects-
  • Excessive thrust, Feed rate too high- Lower feed rate and/or increase speed.
  • Chips being recut- Add more coolant flow.
