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". These Keo® Keyseat (Or Woodruff-Keyseat Style) Cutters Are Made Of High-Speed Steel, With A Left-Hand Cutting Direction. That Means The Cutter Is Intended To Rotate Opposite The Direction Of A Normal Right-Hand Cutter — So That It Cuts When The Spindle Rotates Counter-Clockwise, And The Feed Direction Corresponds Accordingly.

  • Precision cutters made from high-speed steel (HSS) for strength, durability, and reliable general-purpose machining.
  • Designed specifically for Woodruff keyseats, straight keyways, and narrow slots that require a left-hand cutting direction.
  • Ideal for setups where the spindle rotation or feed direction necessitates a left-hand tool.
  • Provides excellent value and versatility for both production and maintenance operations.
  • Titanium Nitride (TiN) is a physical vapor deposition (PVD) coating that forms a thin, extremely hard ceramic layer on the surface of cutting tools.
