Allied Machine 150H-0018-NP Spade Drill Insert 9/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 150H-0018-NP is a cobalt spade drill insert engineered for high-performance holemaking in demanding machining applications. Measuring 9/16 inch in diameter with a 132-degree point angle, this insert fits a Seat Size 0 spade drill holder and belongs to the T-A series. It features an AM200 coating designed to extend tool life and improve chip evacuation in tough materials. Machinists, toolroom technicians, and CNC operators rely on this insert type for consistent, repeatable hole geometry across production runs.

This insert is suited for indexable holemaking operations in metalworking environments including job shops, production machining facilities, and maintenance repair settings. The T-A series spade drill system is commonly used for drilling into carbon steel, alloy steel, cast iron, and stainless steel. The cobalt substrate provides added heat resistance and edge retention compared to standard high-speed steel, making it a practical choice when drilling at elevated feeds and speeds or in interrupted-cut conditions.

Key Features

• 9/16 inch diameter with 132-degree point angle for precise hole geometry
• Cobalt substrate delivers enhanced heat resistance and edge retention
• AM200 coating extends tool life and supports efficient chip flow
• Seat Size 0 designation ensures correct fit in compatible T-A series holders
• Indexable design allows insert replacement without removing the drill body from the machine

Compatibility

Designed for use with Seat Size 0 T-A series spade drill holders. Verify seat size and series designation against your holder specifications before ordering. No additional compatible model numbers were specified in the product data.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per established LOTO procedures. Seat the insert fully into the holder pocket and secure with the appropriate fastener torqued to the holder manufacturer's specification. Inspect the seat and insert pocket for chips or debris before seating to ensure proper contact and accurate hole location. Follow applicable shop safety standards and tool manufacturer guidelines for speeds, feeds, and coolant application.
