What are spiral point taps?

2019-06-17 17:47 | 31 calls
A spiral point tap has a straight, fairly shallow flute and is often referred to as a gun nose. The gun nose or spiral point is designed to drive the swarf forward.

The relatively shallow flutes ensure the sectional strength is maximised. They also act to allow lubricant to reach the cutting edges. This type of tap is recommended for threading through holes.
