Value Collection JY4992400 Straight Flute Tap M7x1.25

Product Description

The VALUE COLLECTION JY4992400 is a straight flute tap designed for cutting M7x1.25 metric special internal threads in ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in general machining and maintenance applications. It features 4 flutes with a plug chamfer, a 6H class of fit for standard tolerance threading, and a D5 thread limit for controlled oversize. Overall length is 2-23/32 inches with a 1-1/8 inch thread length. Machinists, tool and die professionals, and maintenance technicians use this tap for tapping through holes where chip evacuation is managed manually or with cutting fluid.

This tap is suited for creating M7x1.25 metric special threads in workshop, production floor, and field repair environments. The plug chamfer style requires a pre-existing lead or starter hole and works best in through-hole applications where the tap can advance without bottoming out. Right-hand threading direction makes it compatible with standard tap wrenches, tapping heads, and drill press setups. It is appropriate for light to medium duty tapping operations where a high-speed steel tap meets the material hardness requirements.

Key Features

• M7x1.25 metric special thread form for non-standard metric threading requirements
• High-speed steel construction provides hardness and wear resistance for general-purpose tapping
• 4-flute straight design supports chip control in through-hole applications
• Plug chamfer with approximately 3-5 thread lead eases starting and reduces entry force
• 6H class of fit meets standard tolerance requirements for metric threaded fasteners
• D5 thread limit provides consistent oversize control for repeatable thread quality
• Bright, uncoated finish is compatible with most cutting oils and tapping fluids

Compatibility

Designed as a standard replacement or new-application tap for M7x1.25 metric special thread profiles in through-hole configurations across general machining, maintenance, and repair operations.

Installation Notes

This tap should be installed and used by qualified machinists or maintenance professionals familiar with tapping operations and cutting tool safety. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter before starting. Apply appropriate cutting fluid to extend tool life and improve thread finish. Reverse the tap periodically during operation to break chips and prevent binding or tool breakage.
