Allied Machine and Engineering 1C52A-0111 Spade Drill Insert

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52A-0111 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. 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 under high heat and abrasion. The insert measures 1-11/32 inches in diameter with a seat size 2 designation and a thickness of 0.1875 inches. It carries a C5 (P40) manufacturer grade, making it well-suited for interrupted cuts and demanding production drilling applications where carbide rigidity and coating durability are required.

This insert is intended for use in T-A Series spade drill holders with a seat size 2 bore. It is primarily rated for machining steel and hard materials in CNC turning centers, machining centers, and drill press setups. Typical applications include through-hole and blind-hole drilling in manufacturing, tooling, and fabrication environments. Installation and use are performed by machinists and tooling technicians in production or job shop settings.

Key Features

• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• TiAlN PVD coating improves heat resistance and extends tool life in steel and hard material applications
• 132-degree point angle reduces thrust and improves chip formation on entry
• Seat size 2 designation ensures proper fit in compatible T-A Series holders
• C5 (P40) grade carbide suited for interrupted cuts and medium-to-heavy chip loads
• 0.1875-inch insert thickness for consistent seating and repeatable depth control

Compatibility

Designed for use with T-A Series seat size 2 spade drill holders. Primary workpiece material compatibility includes steel (ISO material code P) and hard materials (ISO material code H).

Installation Notes

Insert installation and removal should be performed by a qualified machinist with the spindle fully stopped and the machine locked out per standard LOTO procedures. Use the correct torque driver or insert key specified by the holder manufacturer to seat the insert properly — do not over-tighten or use improvised tools. Inspect the insert seat for chips or contamination before seating a new insert. Discard worn or chipped inserts; do not attempt to regrind solid carbide spade drill inserts in the field.
