Allied Machine 1C50A-.546 Spade Drill Insert 35/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C50A-.546 is a solid carbide spade drill insert designed for high-performance drilling operations in steel and hard materials. Measuring 35/64 inches in diameter with a 132-degree point angle, this insert delivers precise entry geometry and clean hole formation. The TiAlN (Titanium Aluminum Nitride) PVD coating provides thermal resistance and wear protection, extending tool life in demanding cutting conditions. Manufactured to a C5 (P40) material grade, the insert is engineered for use in the T-A series spade drill system. It is installed and changed out by machinist and tool-and-die professionals working with CNC and manual drilling equipment.

This insert is suited for production drilling in steel and hard material workpieces in industrial and manufacturing environments. It fits the T-A series seat size 0 spade drill body system and is appropriate for applications requiring consistent hole diameter and controlled chip evacuation. The 132-degree point angle makes it effective for flat-bottomed entry geometry and general-purpose through-hole drilling in P- and H-classification workpiece materials.

Key Features

• Solid carbide construction rated at C5 (P40) material grade for durability in steel and hard material cutting
• TiAlN PVD coating provides heat resistance and extended tool life at elevated cutting speeds
• 132-degree point angle for precise entry and reduced thrust force
• Designed for T-A series seat size 0 spade drill bodies
• Compact 0.125 inch thickness for low-profile seating in the drill body

Compatibility

Designed for use with T-A series spade drill bodies accepting seat size 0 inserts. Intended for primary workpiece materials classified as P (steel) and H (hard material).

Installation Notes

Installation of spade drill inserts should be performed by a qualified machinist with the machine powered off and the spindle fully locked. Use the appropriate torx or hex key to seat the insert flush and secure against the body pocket before any cutting operation. Ensure the insert is free of chips and debris in the pocket seat prior to tightening to avoid insert rocking or premature failure. Follow the drill body manufacturer torque and clamping guidelines provided with the T-A series body documentation.
