Eagle Cutting Tool MT-040-070-P-I M4.0x0.70 Hss Plug Tap

Product Description

The EAGLE CUTTING TOOL MT-040-070-P-I is an M4.0x0.70 high-speed steel (HSS) metric plug tap designed for cutting internal threads in metal workpieces. The plug chamfer — typically 3 to 5 threads long — makes this tap suitable for through-holes and most standard tapping applications where a starter or bottoming tap is not required. Built from HSS, it offers the hardness and heat resistance needed for general-purpose threading in steel, aluminum, and similar materials. Plumbers, electricians, HVAC service techs, and maintenance professionals keep metric plug taps on hand for field repairs and equipment fabrication tasks.

This tap is intended for M4.0 metric threads with a 0.70 mm pitch, a common fastener size found in light mechanical assemblies, electrical enclosures, HVAC equipment panels, and plumbing fixture components. It is well-suited for use in machine tapping or hand tapping operations in shop and field environments where metric thread standards apply.

Key Features

• High-speed steel (HSS) construction provides hardness and wear resistance
• Plug chamfer design suitable for through-holes and standard tapping applications
• Compact and lightweight at 0.09 pounds for easy handling and portability
• Minimum order quantity of 1 — available as a single-piece purchase

Compatibility

Designed as a standard M4.0x0.70 metric plug tap compatible with conventional tap wrenches, T-handle tap wrenches, and machine tapping chucks that accept industry-standard HSS tap shank sizes.

Installation Notes

Plug taps should be installed by a qualified technician or machinist familiar with thread-cutting procedures. Always secure the workpiece firmly before tapping, use an appropriate cutting fluid to reduce heat and extend tap life, and ensure the tap is started straight to avoid thread misalignment or tap breakage. Follow applicable shop safety practices and equipment manufacturer guidelines when performing tapping operations on energized or pressurized systems — de-energize or depressurize all equipment before any machining work begins.
