Value Collection JY4996245 M27x1.50 Plug Hand Tap Hss

Product Description

The VALUE COLLECTION JY4996245 is a straight-flute hand tap designed for cutting M27x1.50 metric fine internal threads by hand. Built from high speed steel (HSS) with a bright, uncoated finish, this plug-chamfer tap is suited for starting threads in through-holes or finishing pre-started threads with moderate lead-in. The 4-flute geometry provides even chip load distribution across the cutting edges. With an overall length of 4 inches and a thread length of 2.5 inches, this tap is sized for standard hand-tapping setups in machine shops, maintenance environments, and field repair applications. Installation is performed by hand with a tap wrench or adjustable tap handle.

This tap is intended for metric fine thread applications requiring M27x1.50 pitch in ferrous and non-ferrous materials. The D7 thread limit designates the tolerance range of the produced thread, making this tap appropriate for general-purpose metric fine fits. Machinists, tool-and-die workers, and maintenance technicians use plug taps as the primary working tap in most hand-tapping sequences. The bright finish means no coating is present, which suits applications where coating compatibility is a concern or where cutting fluid selection is left entirely to the operator.

Key Features

• M27x1.50 metric fine thread form for precision internal threading
• Plug chamfer provides 3-5 thread lead-in, suitable for through-holes and continuation tapping
• 4-flute straight-flute design distributes cutting load evenly and suits shorter-chip materials
• High speed steel construction handles a broad range of workpiece materials
• D7 thread limit for general-purpose metric fine tolerance fits
• Bright, uncoated finish with no added coating variables

Compatibility

Designed as a standard hand tap for use with M27x1.50 metric fine thread applications. Compatible with any tap wrench or adjustable handle sized for the square drive of this tap shank.

Installation Notes

Secure the workpiece before tapping and ensure the tap is started perpendicular to the work surface to prevent cross-threading. Use an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Apply steady, even pressure and back off periodically to break chips. Inspect the tap and tap wrench for secure engagement before each use.
