Allied Machine 25010H-003I Indexable Spade Drill Taper Shank

Product Description

The ALLIED MACHINE AND ENGINEERING 25010H-003I is an indexable spade drill body designed for deep-hole drilling applications in metalworking and machining environments. Built on the T-A 1 series platform, this extended-length tool accepts interchangeable spade drill inserts and covers a diameter range of 45/64 inches to 15/16 inches with a maximum drill depth of 10-3/4 inches. The 3MT taper shank mounts directly into compatible Morse taper spindles and tailstocks. Through-coolant delivery via two radial entry ports with 1/8 inches NPT threads keeps the cutting zone clear of chips and controls heat during extended cuts. Installed by machinists and tool-room technicians on lathes, drill presses, and machining centers equipped with Morse taper tooling.

This drill body is suited for general-purpose hole-making across a broad range of workpiece materials, including steel, cast iron, aluminum, non-ferrous alloys, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. The extended flute and body length make it appropriate for through-hole and blind-hole applications where standard-length tooling cannot reach depth. The 17-5/32 inches overall length and 13-39/64 inches body length position it for setups where clearance and rigidity must both be managed carefully.

Key Features

• Diameter range: 45/64 inches to 15/16 inches for insert-driven size flexibility
• Extended length with 10-3/4 inches maximum drill depth and 17-5/32 inches overall length
• Helical flute geometry promotes chip evacuation during deep drilling passes
• 3MT taper shank for direct mounting in Morse taper spindles without adapters
• Through-coolant capable via dual radial entry ports threaded 1/8 inches NPT
• T-A 1 series body compatible with 2T-3SR rotary coolant adapter
• General-purpose tool performance across universal workpiece material classifications

Compatibility

Compatible with T-A 1 series indexable spade drill inserts and the 2T-3SR rotary coolant adapter. Shank interfaces with 3MT Morse taper spindles. Workpiece material compatibility codes: H, K, M, N, P, and S.

Installation Notes

Installation is performed by qualified machinists. Power down and lock out the machine spindle before seating or removing the taper shank. Clean the taper bore and shank with a lint-free cloth before mounting to ensure full contact and prevent runout. Verify coolant line connections at the 1/8 inches NPT ports are leak-free before initiating a cut cycle, and confirm the correct spade drill insert is seated and torqued per the insert manufacturer's guidelines.
