Value Collection JY4995825 M8x0.50 Straight Flute Tap 6H Hss

Product Description

The VALUE COLLECTION JY4995825 is a straight flute tap designed for cutting M8x0.50 metric fine internal threads in a variety of workpiece materials. Built from high-speed steel with a bright uncoated finish, this tap delivers reliable thread quality in production and maintenance threading applications. The plug chamfer features a 3-5 thread lead-in, making it suitable for through-hole threading as well as starting threads in blind holes with adequate depth. At 2.719 inches overall length with a 1.125-inch thread length and a D3 thread limit, this tap is sized for standard machine or hand tapping setups. It is designed for right-hand threading and holds a 6H class of fit for general-purpose metric fine fastener applications. Machinists, tool-and-die technicians, and maintenance professionals typically install and use this tap.

This tap is suited for creating M8x0.50 metric fine threads in ferrous and non-ferrous metals, plastics, and similar machinable materials. The 4-flute straight flute design provides chip clearance and thread form stability in moderate-depth holes. Typical use cases include fabrication shops, maintenance and repair operations, and production threading where metric fine fastener standards are required. The bright uncoated surface finish is appropriate for general-purpose materials where specialized coatings are not required. No coolant-through capability is included, so external cutting fluid application is the standard approach for this tap.

Key Features

• M8x0.50 metric fine thread form for precision fastener and close-tolerance applications
• High-speed steel construction for durability across a range of common machinable materials
• 4 straight flutes provide chip clearance and consistent thread form
• Plug chamfer with 3-5 thread lead-in suits both through-holes and adequately deep blind holes
• 6H class of fit meets general-purpose metric internal thread standards
• D3 thread limit provides controlled oversize for proper fit with standard metric fine fasteners
• Right-hand thread direction, compatible with standard tapping equipment and tap wrenches

Compatibility

Designed as a standard straight flute tap for use in machine tapping setups, CNC machining centers, drill presses with tapping attachments, or hand tapping operations requiring M8x0.50 metric fine internal threads.

Installation Notes

Machinists and maintenance technicians should ensure the workpiece is securely fixtured before tapping. Apply appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread quality. Use a properly sized tap drill for M8x0.50 metric fine threads as specified by standard metric tap drill charts. Avoid forcing the tap — back off periodically to break chips, particularly in deeper holes, to prevent tap breakage.
