Value Collection JY4993309 Straight Flute Tap M12x1.75

Product Description

The VALUE COLLECTION JY4993309 is a straight flute tap designed for cutting M12x1.75 metric coarse internal threads in through-holes and accessible blind holes. It features a plug chamfer with 4 flutes and is manufactured from high-speed steel with a bright, uncoated finish. The 6H class of fit and D6 thread limit make it suitable for standard tolerance threading applications. Machinists, tool-and-die makers, and maintenance technicians use this tap when threading steel, cast iron, aluminum, and similar materials by hand or with a tapping machine.

This tap is a general-purpose threading tool suited for production and maintenance environments. The plug chamfer provides a moderate lead-in of approximately 3 to 5 threads, making it appropriate for through-holes and deep blind holes where full thread depth is needed before the bottom. The M12x1.75 metric coarse thread form is one of the most common fastener sizes in metric tooling and machinery applications. It is commonly used in fabrication shops, maintenance facilities, and manufacturing operations requiring standard metric threads.

Key Features

• M12x1.75 metric coarse thread form for one of the most widely used metric fastener sizes
• Plug chamfer with 4 straight flutes for balanced cutting action and chip clearance
• High-speed steel construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish allows visual inspection of cutting edges before and after use
• 6H class of fit and D6 thread limit deliver standard tolerance threads for general fastener assembly
• Right-hand thread direction for conventional tapping operations

Compatibility

Designed as a standard-tolerance replacement or stock tap for any application requiring M12x1.75 metric coarse internal threads with a 6H class of fit and D6 thread limit.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC machine with appropriate tapping cycle. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the drilled hole before beginning the threading operation. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread finish. Do not exceed the rated capacity of the tapping equipment, and reverse the tap periodically to break chips when working in deep or blind holes.
