The cutting dimensions remain the same except for the number of flutes on larger sizes. Previously, the larger-sized tools had 4 or 5 flutes. All SAE J1926 and AS5202 port tools now have 3 flutes

SCT constantly strives to offer the best tools on the market and have found the following benefits favorable for switching to 3 flutes:

  • The tools are less likely to chatter with three flutes which typically results in better finishes to the critical sealing surfaces.
  • It requires less horsepower. This is important and ideal for today’s smaller-sized machines like drill mills.
  • Three-fluted port tools have a larger flute pocket to facilitate better chip evacuation which also gives better surface finishes.

The tools in stock with the old part numbers will be phased out once the stock is depleted.

This following smaller sizes are no longer available with old part numbers:

MS16142-2         MS16142-3           MS16142-4
MS33649-1         MS33649-2         MS33649-3

The smaller sizes were already 3 flute and have been converted to the new part number. If stock with an old part number is unavailable, please switch to the AS5202 and SAE J1926 part numbers for prompt deliveries.
