Value Collection JY9036658 M12x1.5 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9036658 is a straight flute tap designed for cutting M12x1.5 metric fine internal threads in through-holes and blind holes where a bottoming chamfer is required. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread cutting performance in a wide range of workpiece materials. The 4-flute straight flute geometry provides chip control suited to short-chipping materials. With an overall length of 3.375 inches and a thread length of 1.656 inches, the JY9036658 handles standard M12x1.5 threading operations on manual and CNC tapping equipment. A D5 thread limit provides a consistent fit for general-purpose metric fine threaded fastener applications.

This tap is used in machine shops, maintenance facilities, and production environments where M12x1.5 metric fine threads are required. The bottoming chamfer style allows threading to within a few threads of a closed blind hole bottom, making it appropriate for applications where full thread depth near the base of a blind hole is critical. It is installed and used by machinists, tool and die makers, and maintenance mechanics working with metric fine fastener standards.

Key Features

• M12x1.5 metric fine thread form for standard metric fine fastener applications
• Bottoming chamfer allows threading close to the bottom of blind holes
• 4-flute straight flute design suited to short-chipping materials
• High-speed steel construction for general-purpose tapping performance
• Bright uncoated finish for use across a broad range of workpiece materials
• Right-hand thread direction, D5 thread limit for consistent fit tolerance

Compatibility

Designed as a standard M12x1.5 metric fine straight flute bottoming tap compatible with manual tap handles and CNC tapping chucks accepting industry-standard tap shank dimensions for this thread size class.

Installation Notes

Tapping operations should be performed by a qualified machinist following established speeds and feeds for HSS taps in the target workpiece material. Ensure the workpiece is properly secured and the tap is aligned perpendicular to the hole axis before beginning the threading operation. Use an appropriate tapping fluid or cutting oil to extend tool life and improve thread quality. For blind hole applications, confirm the drilled depth provides sufficient clearance below the required thread depth before using a bottoming tap.
