Allied Machine 25030S-125L Indexable Spade Drill 1-13/32 to 1-7/8in

Product Description

The ALLIED MACHINE AND ENGINEERING 25030S-125L is an extended-length indexable spade drill designed for deep-hole drilling operations in industrial machining environments. Part of the T-A 3 series, it accepts interchangeable spade drill inserts and covers a diameter range of 1-13/32 inches to 1-7/8 inches with a maximum drill depth of 13-3/4 inches. The straight-flute body measures 15 inches in length with a 19-inch overall length. Through-coolant capability is standard, with coolant entry via axial concentric and radial channels threaded at 1/4 inches NPT. This drill is installed by machining professionals on CNC lathes, machining centers, and drill presses.

The 25030S-125L is suited for general-purpose deep-hole drilling across a wide range of workpiece materials. Allied Machine designates this tool with primary workpiece material codes H, K, M, N, P, and S, covering cast iron, non-ferrous metals, steel, stainless steel, and high-temperature alloys. It is appropriate for both production and job-shop environments where consistent hole quality at extended depths is required. The flatted cylindrical shank with a 1-1/4-inch diameter provides secure toolholder retention during high-feed operations.

Key Features

• Extended-length design reaches up to 13-3/4 inches drill depth in a single pass
• Diameter range of 1-13/32 inches to 1-7/8 inches accommodates multiple insert sizes
• Through-coolant delivery via axial concentric and radial ports with 1/4 inches NPT threading
• Straight flute geometry with 15-inch flute length supports chip evacuation at depth
• Flatted cylindrical shank at 1-1/4 inches diameter resists rotation under cutting loads
• T-A 3 series platform supports general-purpose performance across universal workpiece materials

Compatibility

Compatible with T-A 3 series spade drill inserts covering the 1-13/32-inch to 1-7/8-inch diameter range. Designed for use in CNC machining centers and drill presses equipped with toolholders accepting a 1-1/4-inch flatted cylindrical shank.

Installation Notes

Installation is performed by qualified machinists. Before mounting, confirm the toolholder bore and retention mechanism are compatible with the 1-1/4-inch flatted shank. Machine spindle and coolant supply must be fully stopped and locked out before inserting or removing the drill body. Verify coolant line connections at the 1/4-inch NPT ports are leak-free before beginning a drilling cycle. Follow the machine tool manufacturer and insert manufacturer recommended feed and speed parameters for the target workpiece material.
