Eagle Cutting Tool DT-1224-I 12-24 Nc Hss Combo Tap Drill

Product Description

The EAGLE CUTTING TOOL DT-1224-I is a combination tap and drill tool designed to perform two operations in a single pass. Made from high-speed steel (HSS), it drills the pilot hole and taps the threads simultaneously, reducing setup time on the job. The DT-1224-I is sized for 12-24 NC (National Coarse) threading, a standard fastener thread found across mechanical and electrical trade work. It is suited for use in hand-held drill drivers or drill presses and is handled by machinists, electricians, HVAC technicians, and other tradespeople who regularly tap threaded holes in sheet metal, enclosures, or light structural material.

The 12-24 NC thread size is widely used in electrical panel work, equipment enclosures, and light mechanical assemblies. This combination tool is appropriate for production and service applications where drilling and tapping the same hole repeatedly is required. It performs best in softer metals such as aluminum, mild steel, and sheet metal where HSS tooling is well suited. The import designation reflects the manufacturing origin and positions this as a cost-effective option for high-volume or general-service use rather than precision or hardened-material applications.

Key Features

• Combination drill and tap in a single tool eliminates the need for a separate drill bit and tap
• 12-24 NC thread form compatible with standard 12-24 fasteners used in electrical and mechanical trade work
• High-speed steel (HSS) construction provides adequate hardness for use in aluminum, mild steel, and sheet metal
• Single-pass operation reduces cycle time when tapping multiple holes
• Compatible with standard drill drivers and drill presses

Compatibility

Designed as a replacement or service-stock combination tap drill for 12-24 NC threading applications in standard drill press or hand-drill setups using a compatible chuck size.

Installation Notes

This tool is installed and operated by machinists, electricians, or HVAC technicians using a drill press or variable-speed hand drill. Always secure the workpiece before drilling and use an appropriate cutting fluid when tapping steel to extend tool life and improve thread quality. Do not exceed the recommended RPM range for HSS tooling in the material being worked. Replace the tool if chipping or dulling is observed to avoid thread damage or breakage in the hole.
