Allied Machine 24020S-125F Indexable Spade Drill 31/32-1-3/8in

Product Description

The ALLIED MACHINE AND ENGINEERING 24020S-125F is an indexable spade drill from the T-A 2 Series, designed for general-purpose hole-making in a wide range of workpiece materials. It covers a drilling diameter range of 31/32 inches to 1-3/8 inches and reaches a maximum drill depth of 7-3/8 inches. The tool features a straight flute configuration with through-coolant capability via axial concentric entry, helping manage heat and chip evacuation during extended drilling operations. The steel body and flatted shank design are standard on production and job-shop machining setups where rigidity and repeatability matter. Machinists and CNC operators are the primary users of this tooling.

The 24020S-125F is suited for production drilling applications in machining centers and CNC lathes where consistent hole quality across multiple material types is required. Its universal workpiece material rating covers steel, cast iron, stainless, aluminum, non-ferrous, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. The standard-length body and straight flute geometry make it a practical choice for typical drilling depths in both horizontal and vertical machining setups. Through-coolant support makes it particularly effective when running at elevated feed rates or when drilling deep holes that require active chip flushing.

Key Features

• Drilling diameter range of 31/32 inches to 1-3/8 inches covers a broad range of bore sizes with a single holder
• Maximum drill depth of 7-3/8 inches with a flute length of 7-3/8 inches supports deep-hole applications
• Through-coolant design with 1/4-inch coolant hole thread size and axial concentric entry (Code 1)
• Flatted cylindrical shank at 1-1/4 inches diameter provides positive drive and resistance to slipping under load
• Universal workpiece material compatibility across six material group codes: H, K, M, N, P, and S
• T-A 2 Series platform supports indexable insert interchange for cost-effective insert replacement without replacing the holder

Compatibility

Compatible with workpiece materials classified under codes H, K, M, N, P, and S, covering steel, cast iron, stainless steel, aluminum, non-ferrous metals, and high-temperature alloys. Designed for use in the T-A 2 Series indexable spade drill system. No additional specific model or machine compatibility data was provided in the product input.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle and toolholder are completely powered down and locked out before inserting or removing the drill body. Verify that the flatted shank is fully seated and the set screw or clamping mechanism is properly engaged before running. Connect through-coolant supply lines according to machine tool specifications before initiating any drilling cycle.
