11mm and larger HS Metric Taper Taps

11mm and larger HS Metric Taper Taps

Metric Taper taps. High Speed Steel. Ground Thread.

To determine the proper drill size for a metric hole-to-be-tapped, just subtract the pitch of the tap from the diameter of the tap to yield the drill diameter.
As an example: a hole-to-be-tapped as 4mm x .7 needs to be drilled with a 3.3mm drill bit.

Basic metric tap types:
Taper tap: 5-6 lead threads ground. The easiest tap for starting to thread a hole.
Plug tap: 3-4 lead threads ground. The most common tap: a "middle ground" tap for threading.
Bottoming tap: 1-2 lead threads ground. Used for continuing to thread a blind hole close to the bottom of the hole. It's difficult to start threading a hole with this tap.
Spiral Point tap: A tap with a chisled point that pushes metal chips ahead of the forming threads. Extremely useful for tapping through-holes (ie holes that extend through the work.) Often machine-driven. Spiral Point taps are not recommended for use in blind holes: the accumulation of chips can tend to bind and break these taps more easily than others.
