Eagle Cutting Tool MT-300-350-P-I M30x3.50 Hss Plug Tap

Product Description

The EAGLE CUTTING TOOL MT-300-350-P-I is an M30.0x3.50 high-speed steel (HSS) metric plug tap designed for cutting internal threads in ferrous and non-ferrous metals. The plug tap chamfer style — typically 3 to 5 threads of lead — makes it suitable for through-hole and moderately deep blind-hole threading applications. At a nominal diameter of 30 millimeters and a 3.50 mm pitch, this tap handles coarse-thread metric fastener specifications commonly encountered in heavy equipment, structural, and industrial fabrication work. Machinists, tool-and-die makers, and maintenance professionals use this tap in manual or CNC tapping operations.

This tap is intended for threading M30x3.50 coarse metric holes in workshop, manufacturing, and field maintenance settings. It is appropriate for use in steel, cast iron, aluminum, and similar machinable materials. The plug chamfer entry makes it a general-purpose choice when starting a thread from a drilled through-hole or when a bottoming tap is not required. It is well-suited for industrial maintenance departments, machine shops, and trade professionals who need reliable metric coarse-thread capability at larger diameters.

Key Features

• M30.0x3.50 coarse metric thread form for large-diameter internal threading
• High-speed steel (HSS) construction provides hardness and wear resistance across common workpiece materials
• Plug chamfer lead for versatile use in through-holes and moderately deep blind holes
• Minimum order quantity of 1, allowing single-unit purchase for service or repair use

Compatibility

Designed for cutting M30.0x3.50 coarse metric internal threads; compatible with standard tap wrenches, T-handle wrenches, and CNC tapping holders sized for the corresponding tap shank diameter.

Installation Notes

This tap should be installed and operated by a qualified machinist or tradesperson familiar with tapping procedures. Before tapping, ensure the workpiece is secured and the pilot hole is drilled to the correct tap-drill diameter for M30x3.50 coarse thread per standard metric tap-drill charts. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Reverse the tap periodically when hand-tapping to break chips and prevent binding or tap breakage.
