Allied Machine 220Y0S-075F Indexable Spade Drill 3/8-27/64 in

Product Description

The ALLIED MACHINE AND ENGINEERING 220Y0S-075F is an indexable spade drill designed for general-purpose hole-making in a wide range of workpiece materials. It accepts interchangeable spade blade inserts, allowing the body to be reused across multiple jobs. The drill features a straight flute geometry, through-coolant capability with axial concentric entry, and a flatted cylindrical shank measuring 3/4 inches in diameter. Maximum drilling depth reaches 1-1/4 inches. Overall length is 4-7/16 inches. This tool is installed and operated by machinists and tool-and-die technicians on CNC machining centers, lathes, and drill presses.

The 220Y0S-075F belongs to the T-A Y Series short-length indexable spade drill line. It is suited for drilling operations in universal workpiece materials including ferrous metals, non-ferrous metals, stainless, high-temperature alloys, and cast materials, corresponding to material codes H, K, M, N, P, and S. The short-length body format is well matched to rigid setups requiring minimal tool overhang and stable cutting conditions. Through-coolant delivery helps manage chip evacuation and heat at the cutting zone during production drilling.

Key Features

• Drilling diameter range of 3/8 inches to 27/64 inches accommodates close-tolerance hole sizing with appropriate blade selection
• Through-coolant support with 1/8-inch coolant hole thread size and axial concentric entry for direct coolant delivery to the cutting edge
• Flatted cylindrical shank at 3/4 inches diameter provides positive drive and resists rotation in the tool holder
• Straight flute design assists chip flow in short-depth drilling applications
• T-A Y Series indexable insert system allows blade replacement without removing the drill body from the spindle
• Short-length classification minimizes deflection in general-purpose production drilling setups

Compatibility

Designed for use with T-A Y Series spade drill blade inserts. Compatible with universal workpiece materials identified by codes H, K, M, N, P, and S, covering a broad range of ferrous and non-ferrous applications. Verify blade insert grade and geometry selection against the specific workpiece material and machine spindle requirements before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with indexable tooling systems. Ensure the machine spindle is fully stopped and the machine is locked out before inserting or removing the tool body or spade blade inserts. Confirm the flatted shank is properly seated and clamped in the tool holder to the holder manufacturer's specification before running the spindle. Through-coolant connections must be verified leak-free and at the correct operating pressure for the machine before initiating a cut.
