Value Collection JY9036641 Straight Flute Tap M12x1.25

Product Description

The VALUE COLLECTION JY9036641 is a straight flute tap designed for cutting M12x1.25 metric fine internal threads in blind holes and bottomed bores. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable thread-cutting performance across a range of workpiece materials. The bottoming chamfer allows threading close to the bottom of a blind hole, making it the right choice when thread engagement near the floor of the bore is required. With 4 flutes and a right-hand thread direction, this tap follows conventional clockwise-drive tooling setups found on most machine tools and tap handles used in metalworking and maintenance environments.

This tap is suited for production machining, tool-and-die work, maintenance and repair operations, and general metalworking applications where M12x1.25 metric fine threads are specified. The metric fine pitch is common in automotive, precision mechanical, and instrumentation assemblies where finer thread pitch provides greater tensile strength and better resistance to loosening under vibration compared to coarse-pitch equivalents. It is installed by machinists, tool-and-die makers, and maintenance mechanics working in shop environments.

Key Features

• M12x1.25 metric fine thread form for precision and vibration-resistant fastener applications
• Bottoming chamfer allows threading to within 1-2 threads of a blind hole floor
• High-speed steel construction provides hardness and wear resistance across common workpiece materials
• 4-flute design for balanced cutting and consistent thread form
• Right-hand thread direction compatible with standard tap wrenches and CNC tapping attachments
• D5 thread limit for controlled fit tolerance in production applications
• Bright, uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a standard straight flute tap for use in any tap wrench, tapping head, or machine tool setup configured for right-hand M12x1.25 metric fine thread cutting operations.

Installation Notes

This tap is installed by machinists and maintenance mechanics using a tap wrench, tapping fixture, or machine tapping attachment. Always ensure the pilot hole is drilled to the correct metric fine tap drill diameter before tapping, and use an appropriate cutting fluid for the workpiece material to extend tool life. Secure the workpiece firmly before applying torque, and back off periodically to break chips when tapping steel or harder materials. Never force a tap into an undersized hole, as this is the leading cause of tap breakage.
