Value Collection JY4996203 Straight Flute Tap M25x1.50

Product Description

The VALUE COLLECTION JY4996203 is a straight flute tap designed for cutting M25x1.50 metric fine internal threads in metallic workpieces. With a plug chamfer, it is suited for threading through-holes and starting threads in blind holes where adequate chip clearance is present. The four-flute configuration provides rigidity and consistent thread form. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable cutting performance across a range of ferrous and non-ferrous materials. The 6H class of fit and D6 thread limit ensure standard tolerance threading compatible with precision metric fastener applications. Machinists and tool and die professionals are the primary users of this tap.

This tap is suited for production and maintenance threading operations where M25x1.50 metric fine threads are required. The plug chamfer style makes it a general-purpose choice for shop use, manual tapping, and CNC tapping operations on mills, lathes, or drill presses. The straight flute design works best in short-chipping materials such as cast iron, brass, and aluminum. A thread length of 2.219 inches (2-7/32 inches) accommodates most standard fastener engagement depths at this thread pitch. Overall length is 4.906 inches (4-29/32 inches), making it compatible with standard tap holders and collet chucks sized for this shank diameter.

Key Features

• D6 thread limit for consistent, repeatable thread quality
• Four straight flutes provide rigidity and support in short-chipping materials
• Plug chamfer style suited for through-holes and starting threads in open blind holes
• High-speed steel construction offers toughness across common shop materials
• Bright, uncoated finish — no additional coating to affect thread tolerance

Compatibility

Designed as an OEM-style replacement or direct-use tap for M25x1.50 metric fine threading applications. Fits standard tap holders, torque arms, and collet chucks sized for the corresponding shank diameter at this tap class.

Installation Notes

Tapping operations should be performed by a qualified machinist. Secure the workpiece firmly and ensure the spindle or tap handle is properly aligned with the pilot hole before beginning thread cutting. Use an appropriate cutting fluid or tapping compound for the material being threaded to reduce friction and extend tap life. Do not force the tap; back off periodically to break and clear chips, particularly in blind-hole applications.
