Value Collection JY4991857 Straight Flute Tap M5x0.90

Product Description

The VALUE COLLECTION JY4991857 is a straight flute plug tap designed for cutting M5x0.90 Metric Special internal threads in through-holes and open-ended blind holes. Manufactured from high-speed steel with a bright uncoated finish, it delivers reliable thread-cutting performance in a range of ferrous and non-ferrous materials. The plug chamfer — typically 3 to 5 thread leads — makes it well suited for through-hole tapping where the tap can advance freely past the bottom of the hole. With 4 flutes and a D3 thread limit, this tap holds close tolerances appropriate for standard metric fastener assemblies. Machinists, toolroom technicians, and maintenance trades keep this size on hand for general production and repair work.

This tap is intended for M5x0.90 metric special threading applications in machine shop, maintenance, and production environments. The 0.875 inch thread length and 2.375 inch overall length make it compatible with standard tap handles, manual tap wrenches, and low-speed machine tapping setups. It is a practical choice for threading operations in steel, aluminum, brass, and similar materials where a straight flute geometry is appropriate and chip evacuation can be managed through proper cutting fluid application and peck-tapping technique.

Key Features

• M5x0.90 Metric Special thread form for non-standard pitch metric fastener applications
• 4-flute straight flute geometry for balanced cutting and rigidity
• Plug chamfer (3-5 thread lead) suited for through-hole tapping
• High-speed steel construction for general-purpose thread cutting across common workpiece materials
• D3 thread limit for consistent tolerance control in metric threaded assemblies
• Bright uncoated finish — ready to use with standard cutting fluids

Compatibility

Designed as a general-purpose straight flute tap for use with standard manual tap wrenches and machine tapping holders accepting industry-standard shank dimensions for M5 taps. No specific compatible model information was provided in the product data.

Installation Notes

Tapping operations should be performed by a qualified machinist or maintenance technician familiar with thread-cutting procedures. Always secure the workpiece firmly and ensure the tap is started square to the hole to prevent tap breakage. Apply an appropriate cutting fluid for the workpiece material and use a peck-tapping motion in blind or deep holes to clear chips. Never force a tap against resistance — back off to break chips and re-apply cutting fluid before continuing.
