Allied Machine 1C53A-0128 Spade Drill Insert 1-7/8in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C53A-0128 is a solid carbide spade drill insert designed for high-performance drilling in steel and hard materials. Measuring 1-7/8 inches in diameter with a 132-degree point angle, this insert seats into Seat Size 3 T-A series spade drill holders. The TiAlN PVD coating provides thermal resistance and wear protection during demanding cutting operations. At 0.1 pounds, the insert is a direct consumable replacement component maintained in tooling inventory by machinists and tool crib technicians in production and job shop environments.

This insert is engineered for use in T-A series spade drill bodies requiring a Seat Size 3 insert. Primary workpiece materials include steel and hard materials, making it suited for structural, die, and tooling applications. It carries a C5 (P40) manufacturer grade, placing it in the ISO P-grade range appropriate for interrupted and continuous cuts in ferrous materials. Typical applications include through-hole and blind-hole drilling on CNC machining centers and manual drill presses in industrial manufacturing settings.

Key Features

• Solid carbide construction with C5 (P40) grade for durability in steel and hard material cutting
• TiAlN coating applied via PVD process for elevated heat resistance and extended tool life
• 132-degree point angle optimized for entry geometry on ferrous workpieces
• Seat Size 3 interface fits T-A series spade drill holders directly
• 1-7/8 inch cutting diameter with 0.25 inch insert thickness
• Sold individually, single-unit packaging for toolroom and line replenishment

Compatibility

Designed for use with T-A series spade drill holders requiring a Seat Size 3 insert. Compatible primary workpiece materials are steel and hard materials as specified by the manufacturer.

Installation Notes

Insert replacement should be performed by a qualified machinist or toolroom technician with the spindle fully stopped and the machine locked out per site lockout/tagout procedures. Seat surfaces on the holder should be inspected and cleaned before seating the new insert to ensure proper clamping geometry. Follow the drill body manufacturer torque guidelines for the clamping screw. Do not use the insert in applications or workpiece materials outside the rated grade designation.
