Value Collection JY9037201 M17x0.5 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9037201 is a straight flute tap designed for cutting M17x0.5 metric special internal threads in a wide range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent performance in general-purpose threading applications. The plug chamfer style provides a gradual lead-in of approximately 3 to 5 threads, making it well suited for through-hole threading. With 4 flutes and a D3 thread limit, the tap maintains accurate 6H class of fit tolerances. Overall length is 3-13/16 inches with a thread length of 1-13/16 inches. Machinists and tool and die professionals select this tap when metric special thread forms are required on production or repair work.

This tap is intended for use in machine shop, maintenance, and toolroom environments where M17x0.5 metric special threads must be cut or repaired. The straight flute geometry works best in shorter-chipping materials such as cast iron, brass, and harder steels. The plug chamfer makes it a practical choice for through-hole applications where the tap can run completely through the workpiece. Right-hand thread direction is standard for conventional metric fastener applications. It is sold individually and is compatible with standard tap holders and tap wrenches sized for the shank diameter.

Key Features

• M17x0.5 metric special thread form for non-standard pitch applications
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Plug chamfer lead-in suits through-hole threading operations
• 4-flute design provides balanced cutting action and thread form accuracy
• 6H class of fit with D3 thread limit for standard tolerance metric threads
• Bright, uncoated finish — no additional coating to affect thread dimensions
• Right-hand thread direction; no coolant-through feature

Compatibility

Designed as an OEM-style replacement or standard toolroom tap for applications requiring M17x0.5 metric special internal threads; fits standard tap holders and tap wrenches accepting the corresponding shank size.

Installation Notes

This tap is installed and operated by machinists or tool and die technicians using a tap wrench, tapping head, or CNC rigid tapping setup. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for M17x0.5 before beginning the tapping operation. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Inspect the tap for wear or damage before each use; a worn or chipped tap can produce out-of-tolerance threads or break in the bore.
