Allied Machine 1C52A-0106 Spade Drill Insert 1-3/16 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52A-0106 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. This insert measures 1-3/16 inches in diameter with a 132-degree point angle and a thickness of 0.1875 inches. It carries a TiAlN (titanium aluminum nitride) coating applied via PVD process, which increases surface hardness and heat resistance during cutting. Rated at manufacturer grade C5 (P40), this insert is built for the rigors of production drilling in ferrous and hard-material applications. It is part of the T-A series, a widely used indexable spade drill platform in industrial machining environments.

This insert fits Seat Size 2 T-A series spade drill holders and is suited for drilling operations in steel and hard materials in CNC machining centers, lathes, and drill presses. Typical applications include production-volume hole-making in structural steel, alloy steel, and similarly rated hard workpiece materials. The C5 (P40) grade designation indicates suitability for interrupted cuts and general-purpose steel machining where toughness is a priority alongside wear resistance.

Key Features

• 1-3/16 inch diameter solid carbide construction for rigidity and wear resistance
• 132-degree point angle optimized for steel and hard material entry
• TiAlN PVD coating improves heat resistance and extends tool life in ferrous materials
• C5 (P40) material grade suited for general-purpose and interrupted-cut steel drilling
• Seat Size 2 T-A series compatibility fits standard indexable spade drill holders
• 0.1875 inch insert thickness provides stable seating in the holder pocket

Compatibility

Designed for use with Seat Size 2 T-A series spade drill holders. Primary workpiece material compatibility includes steel and hard materials per material codes P and H.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill holder is fully removed from the spindle and all machine power is locked out before seating or replacing the insert. Use the appropriate T-A series insert screw and torquing tool as specified by the holder manufacturer to secure the insert in the pocket. Inspect the seat pocket for chips or damage before installation to ensure proper insert contact and runout performance.
