Value Collection JY9037102 Straight Flute Tap M48x1.5

Product Description

The VALUE COLLECTION JY9037102 is a straight flute tap designed for cutting internal metric fine threads in through-holes and blind holes where a bottoming chamfer is required. Built from high-speed steel (HSS) with a bright uncoated finish, this tap cuts M48x1.5 threads to a 6H class of fit with a D6 thread limit. It features 4 flutes for chip clearance and runs right-hand thread direction. With a 2-inch thread length and a 5-inch overall length, this tap is sized for larger-diameter threading applications in metalworking and machining environments. It is installed by machinists and toolmakers on manual lathes, mills, and tapping machines.

This tap is suited for metric fine threading in ferrous and non-ferrous metals where tight tolerances are required. The bottoming chamfer allows threading close to the bottom of a blind hole, making it a common choice for fixtures, machine components, and assemblies that require full thread engagement near the base of the hole. The M48x1.5 designation and 6H fit class are standard in precision mechanical and industrial applications.

Key Features

• M48x1.5 metric fine thread form for precision internal threading
• Bottoming chamfer allows threading to the bottom of blind holes
• 4-flute geometry provides chip clearance during cutting
• 6H class of fit with D6 thread limit for consistent, standards-compliant thread quality
• High-speed steel construction for durability across a range of metals
• Bright uncoated finish suitable for use with cutting fluid in standard tapping operations

Compatibility

Designed as a standard M48x1.5 metric fine straight flute tap for use in manual and CNC tapping operations requiring a 6H class of fit and bottoming chamfer in industrial machining applications.

Installation Notes

This tap should be installed by a qualified machinist familiar with threading operations and proper tap alignment. Always secure the workpiece firmly and ensure the tapping spindle or wrench is aligned perpendicular to the hole before threading begins. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Back the tap out periodically to clear chips, and never force a bottoming tap beyond its thread length into the bottom of a hole.
