Value Collection JY4992459 Straight Flute Tap M8x0.75

Product Description

The VALUE COLLECTION JY4992459 is a straight flute plug tap designed for cutting M8x0.75 metric fine internal threads in a variety of workpiece materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread form in ferrous and non-ferrous metals when used in standard tapping operations. The plug chamfer, with its moderate lead-in, makes it suited for through-hole and moderately deep blind-hole applications. At 2.719 inches overall length with a 1.125-inch thread length, it fits standard tap holders and chucks used in machine shop and field maintenance environments. Machinists, tool-and-die tradespeople, and maintenance technicians are the primary users.

This tap is used in applications requiring metric fine thread pitch in the M8 range, common in automotive, hydraulic fittings, instrumentation, and precision machinery where a finer pitch provides greater holding strength and finer adjustment than the coarse M8x1.25 standard. The right-hand thread direction and D4 thread limit make it compatible with standard tapping fluids and toolholders used in both CNC and manual tapping setups. It does not support coolant-through delivery, so external cutting fluid application is required for optimal tool life and surface finish.

Key Features

• M8x0.75 metric fine thread form for high-strength and fine-adjustment fastening applications
• High-speed steel construction provides hardness and wear resistance across common workpiece materials
• Plug chamfer with 4 flutes supports chip clearance in through-hole and moderate blind-hole tapping
• D4 thread limit maintains consistent fit and tolerance across production runs
• Right-hand thread direction compatible with standard tapping equipment and toolholders
• Bright, uncoated finish allows straightforward visual inspection for wear during service life

Compatibility

Designed as a standard straight flute plug tap for use in any manual or CNC tapping setup capable of driving an M8 tap with a right-hand drive toolholder or tap wrench.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Secure the workpiece fully before tapping to prevent movement and tap breakage. Apply cutting fluid or tapping compound continuously throughout the operation, as this tap does not support coolant-through delivery. Replace the tap at first sign of chip loading, squealing, or increased torque resistance to prevent breakage in the hole.
