METRIC TYPE 3420 - STRAIGHT SHANK - LEFT SPIRAL FLUTES
TYPE
Carbide tips brazed to one piece hardened alloy steel bodies. Left spiral polished flutes.
Designed and manufactured for maximum tool life. Left spiral flutes should only be used on through holes for heat treated steels, hard cast iron and other hard materials. Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots or intersecting holes.
Below is Lexington Cutter's selection of Spiral Flute 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.
