Allied Machine 45YH-.386 Spade Drill Insert Letter W Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 45YH-.386 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. It features a 132-degree point angle and an AM200 PVD coating, delivering extended tool life and heat resistance at the cutting edge. With a seat size of Y and a letter W diameter (9.8 mm), this insert fits directly into compatible GEN2 T-A spade drill holders. It is installed by machinists and tool-room technicians working in production drilling operations where consistent hole geometry and insert durability are critical.

This insert is suited for drilling into a range of ferrous and hard materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. Typical applications include production machining in job shops, manufacturing cells, and CNC turning or milling centers where spade drill tooling is used to reduce cycle times and tooling costs versus twist drills. The GEN2 T-A series is a widely used platform in industrial drilling.

Key Features

• Cobalt insert material for improved toughness and heat resistance in ferrous and hard workpiece materials
• AM200 PVD coating classification for enhanced wear resistance and longer cutting life
• 132-degree point angle optimized for general-purpose drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials
• Letter W diameter (9.8 mm) with seat size Y for precise fit in compatible GEN2 T-A holders
• Thickness of 0.0938 inches for dimensional consistency across insert changes
• Part of the GEN2 T-A series, a standard spade drill platform in industrial machining environments

Compatibility

Designed for use with GEN2 T-A series spade drill holders accepting a seat size Y insert. Compatible with workpiece materials coded P (steel), M (stainless steel), K (cast iron), S (super-alloys and titanium), and H (hard materials).

Installation Notes

This insert is replaced by a machinist or toolroom technician during scheduled tooling changes or at signs of wear. Power down and lock out the machine spindle before removing or seating the insert. Use the appropriate torque wrench and insert screw specified by the holder manufacturer to secure the insert — do not overtighten by hand. Inspect the seat pocket for chips or damage before installing a new insert to ensure proper seating and accurate hole geometry.
