FRACTIONAL TYPE 3437 - STRAIGHT SHANK - LEFT SPIRAL FLUTES - FOR CAST IRON
TYPE
Carbide tips brazed to one piece hardened alloy steel bodies. Left spiral polished flutes.
Left spiral flutes should only be used on through holes and very hard materials. Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots or intersecting holes. NAS 897 chucking reamers manufactured to national aerospace standards 897 C with partial flute length carbide. Tool geometry and carbide grade appropriate for material being machined.
Below is Lexington Cutter's selection of NAS 897 Reamers. We offer a wide variety of carbide tipped and solid carbide cutting tools. Over 95% are in stock either finished or semi finished for fast delivery.
Shanks are ground to the next smallest shank diameter listed in NAS 897 if tool diameter is within .005" of shank diameter.
