Metric Spiral Point Taps For Stainless Steel (Blue Band)

<p><strong>Spiral Point Taps – HSS-E – Blue Ring Series</strong></p>

<p>The Somta Blue Ring Spiral Point Tap range is engineered for high-performance threading in stainless steel. Designed with a forward-angled point, these taps efficiently push chips ahead of the cutting action, reducing clogging and enabling faster, smoother threading—especially in through holes.</p>
