FRACTIONAL TYPE 3432 - STRAIGHT SHANK - RIGHT SPIRAL FLUTES - FOR NON-FERROUS
TYPE 3432
Carbide tips brazed to one piece hardened alloy steel bodies. Right spiral polished flutes.
Right spiral flutes have a greater chip clearing ability for use in blind holes. Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots or intersecting holes. NAS 897 chucking reamers manufactured to 897 C with partial flute length carbide. Tool geometry and carbide grade appropriate for material being machined.
Shanks are ground to the next smallest shank diameter listed in NAS 897 if tool diameter is within .005" of shank diameter.
