Value Collection MSC-04997235 M4x0.70 Spiral Point Tap

Product Description

The VALUE COLLECTION MSC-04997235 is a spiral point tap designed for cutting M4x0.70 metric coarse internal threads in through-hole applications. The spiral point geometry pushes chips forward ahead of the cutting action, reducing chip packing and allowing smoother threading in production and maintenance environments. Constructed from high speed steel with a bright uncoated finish, this tap delivers reliable performance in ferrous and non-ferrous materials at moderate cutting speeds. The plug chamfer distributes cutting load across the leading threads, making it suitable for both hand tapping and machine tapping operations where a gradual thread start is preferred.

This tap is used in general metalworking, toolroom, and MRO applications where M4x0.70 metric coarse threads are required. The 6H class of fit produces a standard tolerance internal thread compatible with 6g class metric fasteners, which represents the most common metric fastener tolerance pairing in commercial and industrial assemblies. It is appropriate for use in machine shops, maintenance facilities, and light manufacturing where metric threading is routine.

Key Features

• Spiral point design pushes chips forward, suited for through-hole threading
• M4x0.70 metric coarse thread form with 6H class of fit tolerance
• 2-flute geometry provides efficient chip evacuation in through-hole applications
• Plug chamfer for gradual thread engagement in hand or machine tapping
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a standard replacement or general-use spiral point tap for applications requiring M4x0.70 metric coarse internal threads with a 6H class of fit in through-hole configurations.

Installation Notes

This tap should be installed and operated by machinists or maintenance technicians familiar with threading operations. Before tapping, ensure the workpiece is securely fixtured and the correct tap drill size for M4x0.70 has been used to prepare the hole. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. When machine tapping, verify spindle speed and feed rate are appropriate for the material and tap size to avoid breakage.
