STEP REAMER TYPE 3482 - STRAIGHT SHANK - LEFT SPIRAL FLUTE LONG CARBIDE - FOR NON-FERROUS
TYPE
Flute long carbide tips brazed to one piece hardened alloy steel bodies. Left spiral polished flutes. Available with cutting or non-cutting pilots.
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 flute long carbide. Tool geometry and carbide grade appropriate for material being machined.
NOTES:
  1. Order must indicate if pilot is cutting or non-cutting and identify material being machined.
  2. The difference between major and minor diameter shall not exceed 6%, and must fall within dimensions shown for that particular tool.
  3. Non-cutting pilot diameters may be smaller than cutting diameter range, but not less than non-cutting pilot minimum diameter dimension shown.
  4. It is recommended that stock removal of 3% be the basis for selecting each cutting diameter.
Below is Lexington Cutter's selection of Step Type 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.
Shank diameter tolerance thru 23/32" tool diameter: +.0000"/-.0010".
Shank diameter tolerance over 23/32" tool diameter: +.0000"/-.0015".
