Type 441 Fractional - Left Spiral Flutes
Carbide Tipped
  • Left spiral polished flutes
  • Arbor hole tapered 1/8" per foot with drive slots
  • Tool diameter tolerance
    thru 1": plus .0001", plus .0005"
    over 1": plus .0002", plus .0006"
  Modifications: (Prompt delivery)
  • Modified tool diameter - priced below
  • Metric tool diameter
  • Cutting diameter reduced for step or pilot
  • End chamfer other than 45ยบ
  • End cutting or corner radius
  • Increased / decreased circular margin
  • Increased / decreased tool diameter back taper
Use:
  • Used only on thru holes for heat treated steels, hard cast irons and other hard materials; left spiral flutes should not be used on blind holes
  • Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots, or intersecting holes
  • Shell reamers are used with an arbor which is tapered to fit the hole in the reamer. Drive slots in the reamer engage lugs on the arbor to supplement the rotational drive from the tapered arbor. The space between the reamer's drive end and the arbor collar permits easy removal of the shell reamer by prying
