Step-by-Step Guide

Prepare the core hole: Drill the proper diameter and lightly chamfer the entry.
Clamp and align: Secure workpiece; insert tap and align axially. The long shank provides clearance.
Apply lubrication: Generously use cutting oil; reapply as needed during cutting.
Cut the thread: Maintain constant speed and feed. Form B drives chips forward—no reverse needed.
Inspect: Clean and check the thread using a screw or gauge.

FAQ

Can this set be used on a bench drill?
Yes, as long as the spindle has reverse function or controlled feed. Always ensure good lubrication.

Why is the tool extra long?
It improves accessibility in deep or recessed thread positions—especially useful in assembly or maintenance work.

Is Form B suitable for blind holes?
No, Form B is optimized for through holes. Use Form C for blind holes.

What’s the correct lubrication?
Use cutting oil suitable for steel; for tough steels, use active oils to minimize friction.

What tolerance can I expect?
Threads meet ISO 2 / 6H for standard fit and accuracy.
