Allied Machine 24005H-075F Indexable Spade Drill 39/64-11/16 in

Product Description

The ALLIED MACHINE AND ENGINEERING 24005H-075F is a T-A 0.5 series indexable spade drill designed for precision hole-making across a wide range of workpiece materials. It covers a drill diameter range of 39/64 to 11/16 inches and reaches a maximum drill depth of 2-1/2 inches. The helical flute design promotes efficient chip evacuation and consistent hole quality. A flatted cylindrical shank measuring 3/4 inches in diameter provides secure toolholder engagement. Through-coolant capability with axial concentric entry supports extended tool life and thermal management during high-feed drilling operations. This tool is installed and operated by machinists and CNC tool-and-die professionals in shop environments.

The 24005H-075F is rated for general-purpose drilling across universal workpiece material groups, including ISO material codes P, M, K, N, S, and H. This covers carbon and alloy steels, stainless steels, cast irons, non-ferrous materials, heat-resistant superalloys, and hardened materials. Typical applications include production drilling on CNC machining centers and drill presses where consistent bore diameter and depth control are required. The standard-length body suits common fixturing setups without requiring extended-reach adaptations.

Key Features

• Drill diameter range of 39/64 to 11/16 inches for flexible bore sizing
• Helical flute geometry for improved chip flow and hole finish
• Through-coolant with 1/8 inch NPT axial concentric entry for heat and chip management
• Flatted cylindrical shank at 3/4 inches diameter for secure drive and anti-rotation
• General-purpose performance across ISO material groups P, M, K, N, S, and H
• T-A 0.5 series platform for compatibility with corresponding Allied insert and holder systems

Compatibility

Designed for use within the Allied Machine and Engineering T-A 0.5 series indexable spade drill system. Compatible workpiece material groups per supplier data include ISO codes P, M, K, N, S, and H.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle and toolholder are fully powered down and locked out before inserting or removing the drill body. Verify the flatted shank is properly seated and clamped in the holder to the toolholder manufacturer's specified retention method before operation. Confirm coolant supply lines are connected and system pressure is verified before initiating a drilling cycle to protect the insert and workpiece.
