Value Collection JY9037516 Straight Flute Tap M39x1.5

Product Description

The VALUE COLLECTION JY9037516 is a straight flute tap designed for cutting M39x1.5 Metric Fine internal threads in a variety of industrial and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread quality in materials suited to standard tapping speeds. The plug chamfer allows for use in through-hole applications, easing entry and reducing the force required to start the cut. With 6 flutes and a 6H class of fit, the tap produces threads that meet standard tolerance requirements for metric fine fastener assemblies. Overall length is 6.0625 inches, with a thread length of 4 inches.

This tap is intended for use in machine shops, maintenance facilities, and manufacturing environments where large-diameter metric fine threads are required. The M39x1.5 designation makes it suitable for precision thread cutting in applications where finer thread pitch improves clamping force or reduces backlash. It is typically used in horizontal or vertical milling machines, drill presses with tapping attachments, or CNC machining centers. Right-hand threading direction is standard for conventional fastener assembly. The D6 thread limit helps control tolerance in production threading operations.

Key Features

• M39x1.5 Metric Fine thread size for large-diameter precision threading
• 6-flute design for improved chip load distribution and thread finish quality
• Plug chamfer for through-hole applications and ease of thread starting
• 6H class of fit meets standard metric thread tolerance requirements
• High-speed steel construction provides durability across a range of workpiece materials
• D6 thread limit supports consistent tolerance control in production use

Compatibility

Designed as an OEM-style replacement or direct-use tap for machine tapping operations requiring M39x1.5 Metric Fine right-hand threads in through-hole configurations.

Installation Notes

This tap is installed and operated by machinists or tool and die professionals using appropriate tapping equipment such as a drill press with a tapping head or a CNC machining center with rigid tapping capability. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter before threading. Use appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread quality. Never reverse the tap abruptly under power; follow standard reversing procedures to clear chips and avoid tap breakage.
