For Sale: used Cincinnati NMTB50 helical drive gear p/n 134602
Not sure what mill or attachment this is used with, but it's a Cincinnati factory drive gear, stamped with p/n "134602" (barely visible stamped on the face of the gear in the first photo below). Based on the size of the gear, I'd guess it's for a No. 3 or larger mill.
Good condition, no broken teeth or gouging on the taper.
Taper = NMTB50 with 1"-8 drawbar thread
Number of teeth = 27
Outside diameter = 5.100"
Width of gear = 2.027"
Projection = 0.871" (distance from taper side of flange to backside of gear, use to match position of gear from column face on attachment)
Pitch diameter = 4.75"
Circular pitch = 0.55"
Two identical gears available, both same condition. $100 each plus actual shipping. Payment by check or PayPal (+3% or F&F).
