Eagle Cutting Tool DT-3750-24-I 3/8-24 Nf Hss Combo Tap Drill

Product Description

The EAGLE CUTTING TOOL DT-3750-24-I is a combination tap and drill tool ground from high-speed steel (HSS) and sized for the 3/8-24 NF (National Fine) thread specification. It combines the drilling and tapping operations into a single pass, reducing setup time and tool changes on the job. Machinists, pipefitters, and mechanical contractors use combination tap drills when threading holes in steel, aluminum, and similar materials where consistent thread form and cycle time both matter. The 3/8-24 NF thread pitch is a common fastener standard in automotive, instrumentation, and mechanical assembly work.

This tool is suited for production and maintenance applications where 3/8-24 NF threaded holes are required in ferrous and non-ferrous metals. It is used in shop environments and field repair scenarios alike, typically in drill presses, CNC equipment, or hand-held power tools where appropriate feed and speed control can be maintained. The HSS construction handles moderate heat and wear under normal cutting conditions without requiring carbide tooling costs.

Key Features

• Combination drill and tap design completes hole creation and threading in a single operation
• High-speed steel (HSS) construction provides durability in ferrous and non-ferrous materials
• 3/8-24 NF thread specification suits fine-thread fastener applications in automotive and mechanical assembly
• Import-grade tooling offers a cost-effective option for general maintenance and production use
• Minimum order quantity of 1, available as a single unit

Compatibility

Designed as an OEM-style replacement and standard tooling option for applications requiring 3/8-24 National Fine threaded holes in drill press, CNC, or compatible hand-held power tool setups.

Installation Notes

Combination tap drills are installed and operated by machinists or qualified mechanical tradespeople. Use recommended cutting fluid for the material being tapped to extend tool life and improve thread quality. Set spindle speed and feed rate appropriate for the workpiece material and tool diameter before beginning the cut. Secure the workpiece firmly before operation to prevent tool breakage or thread damage.
