Allied Machine TAK1-20.00 Spade Drill Insert 20mm Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TAK1-20.00 is a carbide spade drill insert engineered for precision hole-making in demanding machining applications. Designed for use with compatible T-A Pro spade drill holder bodies, this insert features a 132-degree point angle and a physical vapor deposition (PVD) TiAlN coating that improves wear resistance and extends tool life at elevated cutting temperatures. The insert measures 20.00 mm in diameter with a Seat Size 1 designation. It weighs 0.03 pounds and carries a thickness of 0.1563 inches. Installation is performed by qualified machinists and tooling technicians working on CNC or manual drilling operations.

This insert is suited for drilling applications in cast iron and similar ferrous workpiece materials, corresponding to ISO material group K. The T-A Pro series is a modular spade drilling system that allows the insert to be replaced independently of the holder body, reducing tooling cost per hole. Typical use cases include production machining environments where hole diameter consistency and tool change speed are priorities. The 132-degree point angle supports controlled entry and reduced thrust in medium-to-hard workpiece materials.

Key Features

• 20.00 mm cutting diameter with Seat Size 1 for T-A Pro holder compatibility
• Carbide substrate provides rigidity and hardness for ferrous material drilling
• TiAlN PVD coating improves oxidation resistance and extends insert life at high cutting speeds
• 132-degree point angle reduces axial thrust and supports clean hole entry in cast iron
• Modular design allows insert replacement without changing the holder body
• Metric measurement system; primary workpiece material class K (cast iron)

Compatibility

Designed for use with T-A Pro series spade drill holder bodies accepting Seat Size 1 inserts. Intended primary workpiece material is cast iron (ISO material group K).

Installation Notes

Installation and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and spindle locked. Proper seat and screw torque should follow the holder manufacturer specifications for the T-A Pro system. Inspect the holder seat for debris or wear before seating a new insert, as contamination will affect runout and hole quality. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
