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". This Tool Is A Keyseat (Or Keyway) Milling Cutter Engineered For Slotting Operations Such As Keyseats, Woodruff Key Slots, And Similar Radial Slots In Shafts/Hubs. It Combines A Carbide-Tipped Cutting Edge With A Staggered-Tooth Geometry, Mounted On A Steel Shank Body. The Staggered-Tooth Design Improves Cutting Efficiency And Chip Ejection; The Carbide Tips Enhance Wear Resistance, Thermal Stability, And Cutting Speed Capability. For Example: “These Standard Keyseat Milling Cutters Have Carbide-Tipped Steel Cutting Edges That Provide Excellent Wear Resistance, Heat Resistance, And Retain Their Hardness Better Than High-Speed Steel Or Cobalt Steel Cutting Edges. The Body (Shank/Steel) Offers Better Shock Absorption And Flexibility Compared To Solid Carbide Tools, Which Makes It Robust In Typical Milling Setups.

  • Designed for milling Keyseats, Woodruff keyways, and narrow slots to standard dimensions.
  • Combines carbide cutting edges with a tough steel body, providing durability and wear resistance at a lower cost than full-solid carbide.
  • Made in the USA by KEO® Cutter.
  • AlTiN Coated (Aluminum Titanium Nitride) – A high-performance PVD coating known for its exceptional heat resistance, hardness, and oxidation stability.
