Value Collection JY63326730 M4x0.5 Spiral Point Tap Hss

Product Description

The VALUE COLLECTION JY63326730 is a spiral point tap designed to cut internal threads in through-hole applications. Sized at M4 x 0.5 in the Metric Fine thread standard, it uses a plug chamfer lead to progressively engage the workpiece and push chips forward ahead of the cutting flutes. The two-flute geometry keeps the tool profile compact for use in tight clearance areas. The tap is manufactured from high speed steel (HSS) with a bright, uncoated finish and carries a D4 thread limit tolerance. Right-hand thread direction. Suitable for machinists, maintenance technicians, and fabricators working in metal or similar materials.

This tap is intended for threading through-holes in ferrous and non-ferrous metals where chip evacuation forward through the hole is possible. The plug chamfer provides a balance between ease of starting and thread cutting length, making it a practical choice for general production and repair work on M4 threaded fastener applications. The Metric Fine pitch of 0.5 mm is commonly used where vibration resistance or fine adjustment is required, such as in instrumentation, small mechanical assemblies, and precision fixtures.

Key Features

• M4 x 0.5 Metric Fine thread size for precision small-fastener applications
• Spiral point design pushes chips forward through the hole, reducing clogging in through-hole threading
• Plug chamfer for reliable starting and efficient full-thread cutting
• High speed steel construction provides durability across a range of workpiece materials
• D4 thread limit tolerance for consistent fit with standard M4 x 0.5 fasteners
• Bright uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for M4 x 0.5 Metric Fine through-hole threading operations in standard machining and maintenance applications.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC machine spindle. Always drill the correct tap drill diameter for M4 x 0.5 before tapping to avoid tap breakage. Apply appropriate cutting fluid for the workpiece material throughout the operation. Do not reverse the tap under power to break chips — spiral point taps rely on forward chip ejection through the hole.
