Value Collection JY9036492 Metric Coarse Tap Set 3 Pc

Product Description

The VALUE COLLECTION JY9036492 is a 3-piece metric coarse tap set designed for threading operations in metal fabrication, maintenance, and repair work. Built from high-speed steel with a bright, uncoated finish, each tap in the set features 3 flutes for efficient chip evacuation during through-hole and blind-hole tapping. The overall length of 2 inches and a thread length of 0.6875 inches make these taps suitable for compact workpiece access. Thread direction is right hand, and the thread limit is rated D4, indicating the tolerance class for the cut thread. Machinists, millwrights, and maintenance technicians working with metric fastener standards will find this set appropriate for production and field repair applications.

This tap set is suited for use on ferrous and non-ferrous metals where metric coarse thread profiles are required. It is commonly used in machine shops, industrial maintenance environments, and field service settings. The 3-flute geometry provides a balance of chip clearance and tool strength, making it practical for hand tapping and low-speed machine tapping in through-hole applications. The bright finish allows easy inspection of the cutting edges before and after use.

Key Features

• High-speed steel construction for durability in metal threading applications
• 3-flute design promotes chip clearance during tapping
• Metric coarse thread standard for compatibility with common metric fastener profiles
• D4 thread limit for consistent tolerance on cut threads
• Right-hand thread direction, the standard for most metric fastener applications
• Bright, uncoated finish allows straightforward visual inspection of cutting edges

Compatibility

Designed as a standard metric coarse tap set for use in hand tapping and low-speed machine tapping applications requiring right-hand metric coarse threads.

Installation Notes

Tapping operations should be performed by a qualified machinist or maintenance technician using appropriate cutting fluid to extend tool life and improve thread quality. Secure the workpiece firmly before beginning to prevent movement that could break the tap. When hand tapping, use a calibrated tap wrench and advance the tap in short increments, reversing periodically to break chips. Inspect cutting edges before each use and replace worn taps to avoid thread damage.
