Allied Machine 1C53T-0116 Spade Drill Insert 1.5 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C53T-0116 is a solid carbide spade drill insert designed for high-performance hole-making in steel and hard materials. Part of the T-A Series, this insert measures 1-1/2 inches in diameter and seats into a Size 3 holder. The 132-degree point angle is optimized for steel penetration and chip control. A PVD-applied TiN coating reduces friction and extends tool life on ferrous workpieces. At 0.1 pounds, this insert is a direct replacement component used by machinists and tool-and-die professionals in production drilling operations on CNC machining centers and manual lathes.

This insert is suited for drilling operations in steel and hard materials in both production shop and job-shop environments. The T-A Series spade drill system is a modular platform in which the insert is clamped into a reusable holder, allowing fast insert changes without removing the tool body from the spindle. Typical applications include deep-hole drilling in structural steel, alloy steel, and hardened workpieces where solid carbide with a TiN PVD coating provides a measurable advantage over high-speed steel tooling.

Key Features

• 1-1/2 inch diameter solid carbide construction for rigidity and wear resistance
• 132-degree point angle engineered for steel and hard material penetration
• TiN PVD coating reduces friction and extends cutting edge life on ferrous workpieces
• Seat Size 3 compatibility fits standard T-A Series modular holders
• Manufacturer Grade C5 (P40) carbide grade rated for steel cutting applications
• 0.25-inch insert thickness for stable seating in the holder pocket

Compatibility

Designed for use with T-A Series Seat Size 3 spade drill holders. Compatible with primary workpiece materials coded P (steel) and H (hard materials) per ISO material classification. Verify holder seat size before installation.

Installation Notes

Insert installation and removal should be performed by a qualified machinist using the appropriate clamping screws and torque drivers specified by the tool holder manufacturer. Ensure the spindle is fully stopped and the machine is locked out before changing any insert. Inspect the holder pocket for debris, damage, or wear before seating the new insert, as a contaminated or worn pocket will compromise concentricity and reduce insert life.
