Value Collection JY74527367 M18x1.5 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY74527367 is a straight flute tap designed for cutting M18x1.5 metric fine internal threads in a wide range of metalworking applications. Manufactured from high-speed steel (HSS) with a bright uncoated finish, this tap delivers reliable performance in through-hole and blind-hole threading operations. It features 4 flutes and a plug chamfer, making it suited for general-purpose threading where partial thread lead-in is acceptable. The tap has an overall length of 4-1/32 inches and a thread length of 1-13/16 inches, with a shank diameter of 0.5420 inches. Its D6 thread limit designation indicates the tolerance class for the cut thread, which is important when specifying fit for fasteners and mating components.

This tap is used in machine shops, maintenance facilities, and manufacturing environments where metric fine threads are required. The M18x1.5 thread specification is common in automotive, hydraulic, and precision mechanical assemblies. The plug chamfer style makes it appropriate for use in both through holes and sufficiently deep blind holes where a few threads of lead-in are acceptable. It is suitable for use in manual tapping operations as well as low-speed machine tapping setups when properly supported.

Key Features

• M18x1.5 metric fine thread specification for precision threading applications
• 4-flute straight flute design for consistent chip formation in a variety of base materials
• Plug chamfer provides 3-5 threads of lead-in, suitable for through holes and deep blind holes
• High-speed steel (HSS) construction for durability and heat resistance during tapping
• Bright uncoated finish — no additional coating to affect thread tolerance buildup
• D6 thread limit for standard tolerance control on cut threads
• Right-hand thread direction, compatible with standard fastener orientation

Compatibility

Designed as a standard replacement or stock tap for M18x1.5 metric fine threading operations in general metalworking, maintenance, and manufacturing environments.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians using a tap wrench, tapping head, or machine spindle rated for the workpiece material and tap size. Before tapping, ensure the drilled hole is the correct diameter for M18x1.5 metric fine threads per standard drill chart references. Apply appropriate cutting fluid for the base material to reduce heat and extend tap life. Back out periodically to break and clear chips, especially in deeper holes.
