Value Collection JY9037318 M26x1 Straight Flute Tap 4 Flute Hss

Product Description

The VALUE COLLECTION JY9037318 is a straight flute tap designed for cutting M26x1 Metric Special internal threads in ferrous and non-ferrous materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in standard machine shop and maintenance environments. The plug chamfer style provides a moderate lead-in of approximately 3 to 5 threads, making it suitable for through-hole threading applications. With 4 flutes and a right-hand thread direction, it produces clean, accurate threads to a 6H class of fit and D5 thread limit. Machinists, toolroom technicians, and maintenance mechanics install this tap in drill presses, CNC machines, or hand-tapping setups where M26x1 thread profiles are required.

This tap is intended for Metric Special M26x1 threading operations where a fine-pitch, non-standard metric thread is specified. It is commonly used in industrial manufacturing, toolroom work, and precision maintenance applications where standard metric thread sizes do not meet the design requirement. The 2-7/32-inch thread length accommodates a range of workpiece thicknesses, and the 4-29/32-inch overall length is compatible with standard tap holders and machine spindles used for this diameter class.

Key Features

• M26x1 Metric Special thread form for non-standard fine-pitch applications
• High-speed steel construction provides wear resistance across a range of workpiece materials
• Plug chamfer with 3 to 5 thread lead-in suits through-hole threading
• 4-flute design for stable cutting action and consistent thread quality
• 6H class of fit and D5 thread limit ensure dimensional accuracy within standard tolerance
• Bright, uncoated finish works in dry or lubricated cutting conditions
• Right-hand thread direction; no coolant-through feature

Compatibility

Designed as a standard replacement or new-install tap for applications requiring an M26x1 Metric Special internal thread. Fits conventional tap holders, T-handle wrenches, and machine spindle adapters sized for the shank of a tap in this diameter range.

Installation Notes

This tap is installed by qualified machinists or maintenance mechanics using appropriate tap holders, T-handle wrenches, or CNC machine spindles. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap-drill diameter for an M26x1 thread before beginning. Apply a suitable cutting fluid to reduce heat and extend tool life, and back the tap off periodically to break chips when tapping blind holes. Follow applicable shop safety procedures and machine guarding requirements during all tapping operations.
