Allied Machine 24010S-100L Indexable Spade Drill 45/64-15/16in

Product Description

The ALLIED MACHINE AND ENGINEERING 24010S-100L is a T-A 1 Series indexable spade drill designed for general-purpose hole-making in a wide range of workpiece materials. It accepts interchangeable spade drill inserts, allowing insert replacement without removing the holder from the machine. The body features straight flutes and through-coolant capability with axial concentric and radial coolant entry, supporting higher cutting speeds and longer tool life in production drilling applications. With a 1-inch flatted cylindrical shank and an overall length of 10-7/8 inches, this holder fits standard drill press, milling machine, and machining center spindles used by machinist and tooling professionals.

This spade drill holder covers a diameter range of 45/64 to 15/16 inches and reaches a maximum drill depth of 6-5/8 inches, making it well suited for moderate-depth through and blind holes in production and job-shop environments. The universal primary workpiece material classification covers steel, cast iron, hardened materials, non-ferrous metals, non-metallic materials, and superalloys, giving machinists flexibility across a broad range of materials without changing the holder. Standard-length designation suits the majority of common drilling setups where reach is not a limiting factor.

Key Features

• Diameter range from 45/64 to 15/16 inches accommodates multiple insert sizes in one holder
• Through-coolant with axial concentric and radial entry (Coolant Entry Style Code 3) for effective chip evacuation and heat control
• Coolant hole thread size 1/8 inch NPT for direct coolant line connection
• Flatted cylindrical shank (1 inch diameter) provides positive drive and reduces slip in standard toolholders
• Straight flute geometry supports consistent chip flow in through-coolant drilling setups
• General-purpose performance rating across universal workpiece material codes H, K, M, N, P, and S

Compatibility

Designed as an OEM-style T-A 1 Series indexable spade drill holder accepting compatible T-A 1 Series spade drill inserts in the 45/64 to 15/16 inch diameter range. Compatible with machines accepting a 1-inch flatted cylindrical shank. No specific machine model compatibility was stated in the product data.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully de-energized and locked out before mounting or removing the holder. Verify shank seating and drawbar or set-screw engagement before initiating a cut. Confirm coolant line connection at the 1/8 inch NPT coolant port is secure and leak-free before running coolant-through operations.
