Value Collection JY74527300 M8x1 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY74527300 is a straight flute tap designed for cutting M8x1 metric fine internal threads in a variety of materials. Made from high-speed steel (HSS) with a bright, uncoated finish, this tap features 4 flutes and a plug chamfer for smooth thread engagement and efficient chip clearance. With an overall length of 2-23/32 inches and a thread length of 1-1/8 inches, it is suited for production and maintenance threading operations where a straight flute design is appropriate. The right-hand thread direction and D5 thread limit designation make it a standard choice for metric fine threading work in machine shop and maintenance environments.

This tap is intended for use in threading M8x1 metric fine holes in ferrous and non-ferrous metals, plastics, and similar workpiece materials. The plug chamfer style, with typically 3 to 5 threads of lead, makes it suitable for through-holes and deeper blind-hole applications where some lead-in room is available. It is commonly used in manual tapping operations as well as light-duty machine tapping setups in metalworking, maintenance, and repair environments.

Key Features

• M8x1 metric fine thread size for precise fastener fitment in close-tolerance applications
• 4-flute straight design provides stable cutting and efficient chip evacuation
• Plug chamfer allows use in through-holes and blind holes with adequate depth clearance
• High-speed steel construction offers good wear resistance across a range of workpiece materials
• Bright/uncoated finish for general-purpose threading without specialized coating requirements
• D5 thread limit for standard tolerance class fits

Compatibility

Designed as a standard M8x1 metric fine straight flute tap suitable for general threading operations in compatible workpieces where an HSS plug chamfer tap is specified.

Installation Notes

Threading operations should be performed by a qualified machinist or maintenance professional using a properly aligned tap wrench, tapping head, or machine spindle. Always ensure the workpiece is securely clamped and that the correct tap drill size is used for the M8x1 thread prior to tapping. Apply appropriate cutting fluid to extend tool life and improve thread quality. Back the tap off periodically during hand tapping to break chips and reduce the risk of tap breakage.
