Allied Machine 1C52A-1.046 Spade Drill Insert 1-3/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52A-1.046 is a solid carbide spade drill insert designed for high-performance hole-making operations in metal cutting applications. Part of the T-A series, this insert features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that extends tool life in demanding cutting conditions. It carries a C5 (P40) material grade, indicating suitability for interrupted cuts and higher feed rates. At 0.1875 inches thick and 1-3/64 inches in diameter, this insert fits Seat Size 2 T-A series holders. Machinists and tooling professionals install this insert as a replaceable cutting element in spade drill body assemblies.

This insert is suited for drilling operations in steel and hard materials in production machining environments. It is commonly used in CNC machining centers, lathes with live tooling, and dedicated drill presses where consistent hole quality and insert interchangeability are required. The T-A spade drill system allows rapid insert changes without removing the drill body from the machine, reducing downtime on the shop floor. Applications include structural steel fabrication, heavy equipment manufacturing, and general metalworking.

Key Features

• 1-3/64 inch diameter with Seat Size 2 for use in compatible T-A series drill bodies
• Solid carbide construction with C5 (P40) grade for strength and wear resistance in steel cutting
• 132-degree point angle for efficient chip formation and reduced thrust in through-hole and blind-hole drilling
• TiAlN PVD coating improves heat resistance and extends cutting edge life in hard and abrasive materials
• Designed for primary workpiece materials: steel and hard materials (ISO material codes P and H)
• 0.1875 inch insert thickness for precise seating in T-A series holders

Compatibility

Designed for use with Allied Machine and Engineering T-A series spade drill bodies requiring a Seat Size 2 insert. Consult the T-A series holder selection guide to confirm body compatibility with the 1-3/64 inch diameter insert.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine in a de-energized, locked-out state per applicable machine safety procedures. Use the manufacturer-specified insert seating wrench or torque tool to secure the insert in the drill body pocket without over-tightening. Inspect the insert seat and clamping screw for wear or damage before installing a new insert. Follow the T-A series setup instructions for proper insert orientation and seating verification before resuming cutting operations.
