FAQ

What is the difference between taper, plug, and bottom style taps?

Taper style taps start the thread square with the workpiece, plug style taps are used for through holes, and bottom style taps generate the thread to the bottom of blind holes.

Can I use this tap with a power tapper?

Yes, the square shank and robust HSS construction make it suitable for both manual and powered tapping operations.

Is the uncoated finish appropriate for stainless steel?

While the uncoated HSS works well with many metals, for highly abrasive materials like stainless steel, a coated tap may extend tool life, though many users find the uncoated version sufficient for occasional use.

How do I prevent tap breakage?

Use proper lubrication, ensure the tap is aligned with the hole axis, and back off periodically to clear chips and reduce torque buildup.

What pack size should I choose for a small workshop?

If you tap infrequently, a single‑piece pack is economical; for regular production work, the 12‑piece pack offers better value and ensures you have the right size on hand.
