Value Collection JY9037052 M40x2 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9037052 is a straight flute tap designed for cutting M40x2 metric fine internal threads in a wide range of ferrous and non-ferrous materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread quality in moderate-duty tapping applications. It features a bottoming chamfer for threading close to the bottom of blind holes and carries a 6H class of fit with a D7 thread limit for standard tolerance control. The overall length is 5 inches and the thread length is 2 inches. This tool is installed by machinists, tool-and-die makers, and maintenance technicians working with metric fine thread specifications.

This tap is suited for production and maintenance applications requiring M40x2 metric fine threads. The bottoming chamfer makes it particularly useful in blind-hole applications where full thread depth close to the bottom is required. The 4-flute straight flute design provides rigidity and chip control in through-hole and shallow blind-hole tapping. It is appropriate for use in manual tapping operations as well as low-speed machine tapping setups where coolant-through is not required.

Key Features

• M40x2 metric fine thread form for precise, fine-pitch internal threading
• Bottoming chamfer allows threading to near the bottom of blind holes
• 4 straight flutes provide rigidity and support chip evacuation in short-chip materials
• High-speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for general-purpose tapping applications
• 6H class of fit with D7 thread limit for standard tolerance compliance

Compatibility

Designed as a standard replacement or direct-use tap for any application requiring M40x2 metric fine internal threads with a 6H class of fit and bottoming chamfer geometry.

Installation Notes

This tap is installed by qualified machinists or maintenance technicians using a tap wrench, tapping head, or machine spindle rated for the tap size. The workpiece should be securely fixtured and the spindle or drive stopped completely before changing or inspecting the tap. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Follow shop safety protocols and applicable standards for tooling inspection and replacement.
