Allied Machine 27030S-150L Indexable Spade Drill 1-7/8 in

Product Description

The ALLIED MACHINE AND ENGINEERING 27030S-150L is an indexable spade drill engineered for deep-hole drilling operations in metal fabrication and machining environments. It accepts spade blade inserts across a diameter range of 1-13/32 inches to 1-7/8 inches and reaches a maximum drill depth of 22 inches. The tool features a straight flute design, a flatted cylindrical shank measuring 1-1/2 inches in diameter, and through-coolant capability via axial concentric and radial coolant entry. It belongs to the T-A 3 series and is classified as an extra-long tool suited for deep-reach applications. Installation and operation are handled by machining professionals on CNC or manual drilling equipment.

This drill body is intended for general-purpose drilling across a universal range of workpiece materials, including steel, cast iron, aluminum, non-ferrous alloys, high-temperature alloys, and plastics, corresponding to material codes H, K, M, N, P, and S. The extra-long body length and 22-inch flute length make it well suited for deep-bore applications in production machining, job shop work, and heavy-equipment component manufacturing where standard-length tooling cannot reach the required depth.

Key Features

• Diameter range of 1-13/32 inches to 1-7/8 inches accommodates multiple spade blade insert sizes
• 22-inch maximum drill depth with matching 22-inch flute length for full-depth chip evacuation
• Through-coolant system with axial concentric and radial entry (coolant hole thread size: 1/4 inch) keeps cutting zone temperature controlled at depth
• Flatted shank with 1-1/2-inch diameter and 4-inch shank length provides positive drive and resists rotation in the holder
• Straight flute geometry suited for general-purpose drilling across universal workpiece material categories
• T-A 3 series body construction in steel for durability in high-cycle production use

Compatibility

Designed as an OEM-style replacement body for the T-A 3 series indexable spade drill system, accepting standard spade blade inserts compatible with the 1-13/32 inches to 1-7/8 inches diameter range within that series.

Installation Notes

This tool body is installed by qualified machinists on CNC machining centers or manual drill presses with appropriate spindle tooling and holders rated for the 1-1/2-inch flatted shank. Ensure the machine spindle, toolholder, and workpiece fixturing are properly secured before initiating a cut. Connect through-coolant supply at the recommended operating pressure for the machine and verify coolant flow before drilling to depth. Do not exceed the rated drill depth or use the body without a properly seated spade blade insert.
