Product Description

American Standard Woodruff Keyseat Cutters Are Intentionally Manufactured With An Oversized Diameter To Allow For Tool Sharpening. The Diameter Oversize Tolerances For American Standard Woodruff Keyseat Cutters Are As Follows: +.010" To +.015" For Diameters 1/4" Through 3/4"; +.012" To +.017" For Diameters 7/8" Through 1-1/8"; And +.015" To +.020" For Diameters 1-1/4" Through 1-1/2". The “Cobalt” Version Of Keo®’S Keyseat Cutters Are Slotting Or Woodruff Key-Seat Cutters Made Of Cobalt-Alloy Tool Steel (Sometimes Labelled Hss-Co) That Provide Higher Speed/Cutting Capability And Greater Wear-Resistance Compared To Standard Hss Versions. They Are Still Built As Keyseat Cutters (For Woodruff Keysets Or Narrow Slots), Designed Around Matching Key/Slot Standards.

  • Manufactured from premium cobalt high-speed steel (HSS-Co) for superior hardness and heat resistance.
  • Designed for machining Woodruff keyseats, straight keyways, and narrow slots to precise standard dimensions.
  • Offers a performance step-up from standard HSS cutters—ideal for tougher materials and higher-speed operations.
  • Combines durability, edge retention, and cost-effectiveness for general to heavy-duty keyseat work.
  • AlTiN Coated (Aluminum Titanium Nitride) is a high-performance PVD (Physical Vapor Deposition) coating engineered for extreme temperature resistance, exceptional hardness, and superior oxidation stability.
