Value Collection JY4994406 Straight Flute Tap M22x2.50

Product Description

The VALUE COLLECTION JY4994406 is a straight flute plug tap designed for cutting M22x2.50 metric coarse internal threads in through-holes and open-bottomed blind holes. Manufactured from high-speed steel with a bright, uncoated finish, this tap offers the hardness and wear resistance needed for general-purpose threading in steel, cast iron, aluminum, and similar materials. With 4 flutes and a plug chamfer of approximately 3 to 5 threads, it is suited for production threading work where chips can clear forward through the hole. Licensed machinists and tool-and-die professionals are the primary users of this tap in both manual and CNC tapping operations.

This tap is intended for metric coarse threading applications in machine shops, maintenance facilities, and manufacturing environments. The M22x2.50 thread size is common in heavy mechanical assemblies, structural fastener repairs, and equipment manufacturing. The plug chamfer style makes it a versatile choice for starting threads in through-hole applications where a full bottom thread form is not required. At 4.6875 inches overall length with a thread length of 2.21875 inches, it fits standard tap holders and machine spindles used in typical shop setups.

Key Features

• M22x2.50 metric coarse thread form for use in standard metric fastener applications
• Plug chamfer for reliable thread starts in through-holes and open blind holes
• 4 straight flutes for chip clearance and consistent thread form
• High-speed steel construction provides hardness suitable for ferrous and non-ferrous workpiece materials
• Bright, uncoated finish allows visual inspection of cutting edges before and after use
• D4 thread limit for controlled tolerance fit in standard metric threaded assemblies

Compatibility

Designed as a standard OEM-style straight flute plug tap for use in manual tap handles, tapping heads, and CNC machine tool holders sized for M22 taps.

Installation Notes

Threading operations with this tap should be performed by a qualified machinist following established shop practices. Secure the workpiece fully before beginning the tapping cycle and use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. For hand tapping, use a properly sized tap wrench and advance the tap in consistent increments, backing off periodically to break chips. Inspect the tap for chipping or wear before each use and replace if cutting edges show damage.
