Value Collection JY4994208 Straight Flute Tap M20x2.50

Product Description

The VALUE COLLECTION JY4994208 is a straight flute tap designed for cutting M20x2.50 metric coarse internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap suits general-purpose tapping where consistent thread quality is required. The 6H class of fit delivers standard tolerance threads appropriate for most metric fastener applications. With a D7 thread limit, 4 flutes, and a 2-inch thread length, it handles through-hole and shallow blind-hole work in production or maintenance settings. Machinists, tool-and-die tradespeople, and maintenance mechanics are the primary users.

This tap is suited for use in machine shops, maintenance and repair operations, and fabrication environments where M20 metric coarse threads are required. The plug chamfer - with a moderate lead-in taper - makes it appropriate for through-hole applications and for starting threads in blind holes where adequate depth allowance exists. The right-hand thread direction is standard for the vast majority of metric fastener assemblies. It is compatible with standard tap wrenches, tapping arms, and CNC tapping cycles when used with appropriate holders.

Key Features

• M20x2.50 metric coarse thread form for standard metric fastener compatibility
• Plug chamfer provides moderate lead-in taper, suitable for through-hole and deeper blind-hole applications
• 4-flute design offers good chip clearance in a range of workpiece materials
• High-speed steel construction provides durability across general-purpose tapping operations
• Bright, uncoated finish - suitable for use with standard cutting fluids
• 6H class of fit meets standard tolerance requirements for metric threaded assemblies

Compatibility

Designed as a standard-geometry straight flute tap for use in general-purpose M20x2.50 metric coarse tapping applications with tap wrenches, tapping heads, or compatible CNC toolholders.

Installation Notes

Installation should be performed by a qualified machinist or maintenance mechanic following standard tapping procedures. Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled pilot hole before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Never reverse a tap while chips are present without first clearing the flutes, as this can cause breakage.
