  • 1 13/16 in overall length fits standard tap wrenches

Tap Set M2.5 Metric Threading

This three-piece set provides taper, plug and bottoming hand taps for M2.5 x 0.45 metric threads. The high-speed steel tools are bright finished and uncoated for general-purpose threading work. They suit maintenance, repair and light production tasks where a complete thread form is required.

Sustained Cutting Performance

High-speed steel construction retains hardness during repeated hand-tapping operations without the rapid edge loss seen in carbon steel. The three-flute design clears chips steadily through the 1/2 inch thread length, reducing binding during deep or blind holes. Bright finish offers no lubricity, so cutting fluid is essential for consistent results.

Installation and Common Issues

Taps are turned by hand with a suitable wrench; no power-drive shank is included. The D3 limit and 6H class of fit demand accurate drill size and alignment to avoid oversize or bell-mouthed threads. Breakage often occurs when the bottoming tap is forced without clearing chips or when lubrication is omitted.

Questions about this item

How much heat does the M2.5 HSS tap generate during continuous pneumatic tapping?

The uncoated high-speed steel tap produces typical cutting heat for M2.5 metric threads; use cutting fluid and allow cooling pauses during extended runs.

What pneumatic tool holder or chuck is required to drive the 1/2 in thread-length taps?

A 3-flute compatible collet or tap holder that accepts 1 13/16 in overall length shanks is needed for secure drive.

Will the D3 class-of-fit threads mate correctly with existing 6H nuts and bolts?

Yes, the D3 limit on a 6H class-of-fit tap cuts internal threads that assemble with standard M2.5 x 0.45 external threads.
