Allied Machine 483H-0113 Spade Drill Insert 1-13/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 483H-0113 is a cobalt spade drill insert designed for high-performance drilling applications in demanding industrial environments. Part of the GEN2 T-A series, this insert features a 1-13/32 inch diameter and a 132-degree point angle, making it well-suited for precise hole entry and chip control in tough materials. The AM200 PVD coating provides enhanced wear resistance and extended tool life under high cutting speeds. At 0.25 inches thick, this insert seats into a Size 3 holder and is intended for use by machinists and toolroom professionals operating drill presses, CNC machining centers, or manual lathes with drilling capability.

This insert is engineered for cutting steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. The GEN2 T-A platform is a common choice in production machining environments where consistent hole quality and insert interchangeability across a standardized holder system are required. Typical applications include through-hole and blind-hole drilling in structural components, manifolds, and aerospace or industrial fabrication work where material hardness and work-hardening tendencies demand a high-cobalt substrate with a durable PVD coating.

Key Features

• 1-13/32 inch diameter cobalt insert for the GEN2 T-A spade drill system
• 132-degree point angle for controlled entry and reduced thrust in hard materials
• AM200 PVD coating for elevated wear resistance and extended tool life
• Compatible with ISO material groups P, M, K, S, and H including super-alloys and titanium
• Seat Size 3 for proper indexing and secure clamping in matching holders
• 0.25 inch insert thickness ensures rigid support during high-feed drilling operations

Compatibility

Designed for use with GEN2 T-A series Seat Size 3 spade drill holders. No additional specific model or holder numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping and torque procedures for Seat Size 3 inserts. Ensure the machine spindle is fully stopped and locked out before seating or removing any insert. Inspect the holder pocket for debris or wear before installation to ensure proper seating and prevent premature insert failure. Follow shop safety protocols and applicable ANSI or OSHA machining standards when operating drilling equipment.
