Eagle Cutting Tool MT-390-300-P-I Hss Metric Plug Tap

Product Description

The EAGLE CUTTING TOOL MT-390-300-P-I is an M39.0x3.00 high-speed steel (HSS) metric plug tap designed for cutting internal threads in metal workpieces. The plug chamfer style makes it suited for threading through-holes and moderately deep blind holes, as it provides a gradual lead-in that distributes cutting forces across several threads. At 2.03 pounds, this is a full-size industrial tap intended for use in a tapping machine, drill press, or manual tap wrench setup where precise alignment is maintained. HSS construction provides the hardness and wear resistance needed for production tapping in steel, cast iron, aluminum, and similar machinable materials.

This tap is used in machining and metalworking applications where M39.0x3.00 metric threads are required. The M39 diameter with a 3.00 mm pitch is a coarse-thread specification common in heavy industrial and structural fastener applications. It is typically installed by machinists, toolroom technicians, and maintenance trades performing heavy repair or fabrication work. Applications include threading large-diameter bolt holes in machine bases, flanges, heavy equipment frames, and structural components.

Key Features

• M39.0x3.00 metric coarse thread specification for large-diameter internal threading
• Plug chamfer provides a tapered lead-in across several threads for controlled cutting entry
• HSS construction delivers hardness and thermal resistance for tapping ferrous and non-ferrous metals
• Full-size industrial tap at 2.03 pounds, built for machine or hand-tapping setups
• Minimum order quantity of 1 unit allows single-tool procurement

Compatibility

Designed as an OEM-style cutting tool replacement or new-application tap for any machine or hand-tapping setup requiring M39.0x3.00 metric coarse internal threads.

Installation Notes

This tap is installed by qualified machinists or maintenance technicians. Before tapping, ensure the pilot hole is drilled to the correct tap-drill diameter for M39.0x3.00 per standard metric thread charts, and secure the workpiece firmly. Use an appropriate cutting fluid for the material being threaded to reduce heat and extend tool life. When using a tap wrench, maintain perpendicular alignment to avoid tap breakage.
