Allied Machine 24040S-150F Indexable Spade Drill 1-29/32 to 2-9/16 in

Product Description

The ALLIED MACHINE AND ENGINEERING 24040S-150F is an indexable spade drill body designed for deep-hole drilling operations in a wide range of workpiece materials. Part of the T-A 4 series, it accepts interchangeable spade drill inserts and supports drilling diameters from 1-29/32 inches to 2-9/16 inches at depths up to 9-1/8 inches. The body features a flatted cylindrical shank measuring 1-1/2 inches in diameter and is built from steel for rigidity under heavy feed rates. Through-coolant delivery via axial concentric entry keeps the cutting zone clear of chips and controls heat during extended cuts. This tool is installed by machinists and toolroom professionals on CNC machining centers and manual boring mills.

The 24040S-150F is suited for general-purpose drilling in production and job-shop environments. Its universal material compatibility rating covers a broad spectrum of workpiece materials including steel, stainless, cast iron, aluminum, nonferrous alloys, and high-temperature alloys. Straight flutes support efficient chip evacuation in through-hole and blind-hole applications where coolant pressure assists in flushing swarf. The standard-length configuration fits common tool-holding systems sized for 1-1/2 inch shank drills.

Key Features

Compatibility

Designed as an OEM-compatible T-A 4 series spade drill body accepting standard indexable spade drill inserts for the stated diameter range. Compatible with universal workpiece material codes H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists. Ensure the machine spindle and coolant supply are fully shut down and locked out before mounting or dismounting the drill body. Verify shank seating and retention in the tool holder before initiating a cut, and confirm coolant flow is active prior to engaging the workpiece to prevent insert damage. Follow the insert manufacturer torque specifications for clamping screws when seating spade drill inserts.
