Value Collection JY74527359 M14x2 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY74527359 is a straight flute tap designed for cutting M14x2 metric coarse internal threads in through-holes and open-ended applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread formation in a wide range of ferrous and non-ferrous materials. The plug chamfer — tapered over approximately 3 to 5 threads — allows the tap to start in a chamfered or pre-drilled hole without requiring a taper tap first. At 3.5625 inches overall length with a 1.65625-inch thread length, it fits standard tap wrenches and machine holders for the 0.4290-inch shank diameter.

This tap is suited for job-shop machining, maintenance and repair operations, and production threading where M14x2 metric coarse threads are required. The 4-flute, straight-flute geometry works best in through-hole applications where chips can exit freely. The 6H class of fit produces standard-tolerance metric threads appropriate for most bolted assemblies and general mechanical fastening. The D7 thread limit indicates the tap is ground to produce threads at the high end of the 6H tolerance range, accounting for slight spring-back in common materials.

Key Features

• M14x2 metric coarse thread form for standard metric fastener compatibility
• High-speed steel construction provides toughness and wear resistance across a range of workpiece materials
• Plug chamfer starts cleanly in pre-drilled through-holes without a separate taper tap
• 4 straight flutes promote chip clearance in through-hole threading operations
• 6H class of fit with D7 thread limit produces tolerance-correct threads for general mechanical assemblies
• Bright, uncoated finish — no additional break-in required; compatible with most cutting fluids

Compatibility

Designed for use in any tap wrench, T-handle, or machine tapping setup accepting a 0.4290-inch shank diameter. Cuts M14x2 metric coarse right-hand internal threads per standard metric thread specifications.

Installation Notes

Secure the workpiece firmly before tapping and ensure the pilot hole is drilled to the correct tap-drill diameter for M14x2 threads. Use an appropriate cutting fluid or tapping compound for the workpiece material to reduce friction and extend tap life. Apply steady, even pressure and back off periodically to break chips when tapping by hand. Avoid forcing the tap if resistance increases suddenly — back out, clear chips, and reapply cutting fluid before continuing.
