Value Collection JY9036427 Metric Coarse Tap Set Hss

Product Description

The VALUE COLLECTION JY9036427 is a 3-piece metric coarse tap set designed for cutting internal threads in metal workpieces. Built from high-speed steel (HSS) with a bright uncoated finish, this set delivers reliable performance across a range of threading applications. Each tap features 4 flutes for efficient chip evacuation and a right-hand thread direction. The overall length is 3-13/16 inches, with a thread length of 1-13/16 inches. The D7 thread limit designation indicates a Class 3B tolerance range, making these taps suitable for threading applications requiring close fits. Machinists, maintenance technicians, and toolroom professionals rely on sets like this for production and repair threading work.

This tap set is suited for threading metric coarse threads in ferrous and non-ferrous metals in machine shop, maintenance, and fabrication environments. The 4-flute design works well in through-holes and blind holes where chip clearance is a consideration. The HSS construction handles moderate cutting speeds and is compatible with standard tapping fluids and cutting oils. This set is appropriate for bench work, drill press tapping, and CNC tapping operations where metric coarse thread forms are required.

Key Features

• 4-flute geometry promotes efficient chip evacuation during tapping
• Bright uncoated finish suitable for use with standard cutting oils and tapping fluids
• Right-hand thread direction for standard metric coarse threading applications
• D7 thread limit for Class 3B tolerance threading work
• 3-piece set provides multiple tap stages for progressive thread cutting

Compatibility

Designed as an OEM-style replacement or standard toolroom tap set for metric coarse threading applications in metalworking and maintenance environments.

Installation Notes

Tap installation and use should follow standard machining safety practices. Secure the workpiece before tapping, and use an appropriate tapping fluid or cutting oil to extend tap life and improve thread quality. Apply consistent, even torque and back off periodically to break chips when tapping blind holes. Replace any tap showing signs of wear or damage before continuing work to avoid thread damage or tap breakage.
