Tap, M3x0.5 Metric, Spiral Point, TiN Coated 

High speed steel (HSS) spiral point plug style taps with a titanium (TiN) coating.

Spiral point style plug taps have the same general tap dimensions as straight flute taps however they have the first few threads cut at an angle which enhances the removal of chips from the cutting surface. This design makes spiral point taps ideal for production tapping of through holes.

The flutes on a spiral point tap are more shallow than those of a conventional tap resulting in more surface area for cutting, making them stronger thereby allowing for higher cutting speeds and less power required for the tap to travel.

These metric taps comply with standard tap dimensions as defined in DIN 371. The thread tap limits (pitch diameter limits) is D3 (plus 0.0015).
