Value Collection MSC-04997474 M8x1 Spiral Point Tap Hss

Product Description

The VALUE COLLECTION MSC-04997474 is a spiral point tap designed for cutting M8 x 1 metric fine internal threads in through-hole applications. Manufactured from high speed steel (HSS) with a bright uncoated finish, this plug chamfer tap features 2 flutes and a right-hand thread direction. The spiral point geometry pushes chips forward ahead of the cut, making it well suited for tapping through holes where chip evacuation would otherwise cause problems. The 1.125-inch thread length provides adequate engagement for standard fastener depths in this thread class.

This tap is intended for use in production and maintenance environments where M8 x 1 metric fine threads are required. Metric fine threads offer a tighter pitch than coarse equivalents, making them common in precision assemblies, automotive components, hydraulic fittings, and instrumentation where vibration resistance or fine adjustment is needed. The plug chamfer style provides a moderate lead-in, balancing starting ease with usable thread length. It is appropriate for use in manual tapping handles, CNC rigid tapping, or drill press setups on ferrous and non-ferrous materials.

Key Features

• M8 x 1 metric fine thread form for precision threading applications
• High speed steel construction provides durability across a range of workpiece materials
• Spiral point geometry advances chips forward, reducing clogging in through-hole tapping
• Plug chamfer offers balanced lead-in for both hand and machine tapping
• Right-hand thread direction, compatible with standard toolholders and tap handles
• Bright uncoated finish suitable for general-purpose use

Compatibility

Designed as an OEM-style replacement or general-purpose tap for applications requiring M8 x 1 metric fine right-hand internal threads in through-hole configurations.

Installation Notes

This tap should be installed in a suitable tap handle, tapping head, or rigid tapping chuck appropriate for the shank size. Always ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill diameter for M8 x 1 before tapping. Use a cutting fluid appropriate for the workpiece material to reduce heat and extend tool life. Do not force the tap if resistance increases unexpectedly, as HSS taps are susceptible to breakage under side load or binding.
