Allied Machine 24010H-004IS045 Indexable Spade Drill 4MT

Product Description

The ALLIED MACHINE AND ENGINEERING 24010H-004IS045 is an indexable spade drill designed for steel machining in general-purpose drilling applications. This tool features a helical flute geometry, a 4MT taper shank, and through-coolant capability for effective chip evacuation and heat management during deep-hole drilling operations. The drill produces a 0.7087 inch (18.00 mm) diameter bore with a maximum drill depth of 4.75 inches and an overall length of 10.75 inches. The steel body construction suits heavy-duty cutting environments. It is installed by machinists and CNC operators in production and job-shop settings where consistent hole geometry in steel workpieces is required.

This spade drill is intended for use on steel workpieces, classified under primary workpiece material code P. Its standard-length body of 5.875 inches and standard flute length of 5.875 inches position it for typical production drilling scenarios. The T-A SS 1 series designation identifies it within Allied Machine and Engineering's T-A indexable drilling platform. The axial concentric and radial coolant entry style (code 3) supports both internal and external coolant delivery, making it well suited for vertical machining centers, lathes, and drill presses equipped with through-spindle coolant systems.

Key Features

• Helical flute geometry promotes efficient chip evacuation in steel drilling
• Through-coolant capability with axial concentric and radial entry (code 3) for thermal control
• 4MT taper shank provides rigid, secure tool holding on compatible machine spindles
• 0.7087 inch (18.00 mm) cutting diameter with 4.75 inch maximum drilling depth
• Steel body construction rated for general-purpose P-material (steel) applications
• Indexable insert design enables insert replacement without removing the drill body

Compatibility

Designed for use with Allied Machine and Engineering T-A SS 1 series indexable spade drilling systems. Compatible with machine tool spindles accepting a 4MT (Morse Taper 4) shank connection. Suitable for machining steel workpieces (primary workpiece material code P) in general-purpose applications.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing the drill body. Verify taper shank seating and cleanliness before securing the tool, as contaminants in the taper socket can cause runout and premature insert wear. Confirm through-coolant supply lines are connected and flushed before initiating a cutting cycle.
