Allied Machine 23015H-100F Indexable Spade Drill Helical

Product Description

The ALLIED MACHINE AND ENGINEERING 23015H-100F is an indexable spade drill designed for precision hole-making in a wide range of workpiece materials. It accepts interchangeable spade drill inserts, making it a cost-effective tooling solution for production and job-shop environments. The drill covers a diameter range of 55/64 to 15/16 inches with a maximum drill depth of 4-5/8 inches. A helical flute geometry promotes efficient chip evacuation, and through-coolant capability via a 1/8-inch NPT axial concentric entry port helps maintain cutting temperatures and extend insert life. Licensed machinists and tooling specialists are the primary installers of this holder in CNC machining centers and drill presses.

The 23015H-100F belongs to the T-A 1.5 series and is rated for general-purpose performance across universal workpiece material groups, including ferrous, non-ferrous, cast iron, and heat-resistant alloys (material codes H, K, M, N, P, S). Its intermediate-length classification suits typical through-hole and blind-hole operations in production environments where balanced reach and rigidity are required. The cylindrical shank with flatted drive is compatible with standard toolholders sized for a 1-inch shank diameter.

Key Features

• Diameter range: 55/64 to 15/16 inches for close-tolerance bore sizing
• Helical flute design promotes positive chip flow and reduced cutting forces
• Through-coolant delivery via 1/8-inch NPT axial concentric entry for improved tool life
• Flatted cylindrical shank prevents rotational slippage in standard toolholders
• T-A 1.5 series intermediate-length body balances reach and rigidity
• Universal material compatibility covers steel, cast iron, aluminum, non-ferrous, stainless, and high-temp alloys

Compatibility

The 23015H-100F is part of the Allied Machine T-A 1.5 series and accepts T-A series indexable spade drill inserts rated for the corresponding diameter range. It is designed for use with standard toolholders accommodating a 1-inch flatted cylindrical shank. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is properly torqued to the machine manufacturer's specifications before securing the shank. Verify coolant line connections to the 1/8-inch NPT port are leak-free and that system pressure is appropriate for the application before initiating a cut. Inspect the spade insert seating and locking screw torque each time the insert is indexed or replaced.
