Use for engraving and routing with CNC, pantograph or duplicating machines. Made of premium high-speed steel, individually heat-treated to extreme hardness of 62–65 HRC in a process that retains toughness. Not as durable as carbide cutters but very effective for applications that require greater tip resiliency, such as making deep, fine cuts.

We suggest that they be ground by either plunge-cut or cross-feed method with a soft grinding wheel. All centerless ground to a close tolerance of +.0000″/–.0002″, with flats that are within .001″ above center.
