Allied Machine 1C52A-0105 Spade Drill Insert 1-5/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C52A-0105 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 1-5/32 inches in diameter and seats in a Size 2 holder. It features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating applied to C5 (P40) grade carbide substrate. The coating reduces heat buildup and extends tool life in demanding ferrous cutting applications. Machinists and toolroom professionals install this insert in compatible T-A series spade drill bodies for production drilling operations.

This insert is suited for drilling steel and hard materials in CNC machining centers, lathes, and drill presses where a replaceable-tip spade drill system is in use. The T-A series platform is a common choice in production environments where insert changeout speed matters. The 1-5/32 inch diameter and Size 2 seat make this insert a direct fit for corresponding T-A series bodies used in medium-diameter hole applications typical of job shop and production machining work.

Key Features

• 1-5/32 inch diameter with Seat Size 2 for T-A series spade drill bodies
• Solid carbide construction, C5 (P40) grade, for rigidity and wear resistance
• 132-degree point angle optimized for entry and chip formation in steel
• TiAlN PVD coating reduces friction and extends tool life in ferrous and hard materials
• Designed for primary workpiece materials classified as Steel (P) and Hard Material (H)
• 0.1875 inch insert thickness for consistent seating in the holder

Compatibility

Designed for use with ALLIED MACHINE AND ENGINEERING T-A series spade drill bodies accepting a Size 2 seat and a 1-5/32 inch diameter insert.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Seat the insert fully in the holder pocket and secure per the body manufacturer torque procedure using appropriate insert screws and a calibrated torque driver. Inspect the seat and clamping surfaces for chips or debris before each insert installation to maintain concentricity and prevent premature insert failure.
