Unique Bargains 3pcs Metric Hand Tap and Die Set M12 x 1 Taper/Bottom Thread Taps + Round Die Tap and Die Kit Hand Threading Tapping Tools for Repair

Made from 9SiCr alloy tool steel, this tap and die set offers excellent hardness, toughness, and wear resistance, with an uncoated finish for good cutting performance across a wide range of threading applications.

The set includes a taper tap for starting threads in through holes, a bottom tap for threading near the bottom of blind holes, a straight flute tap for fast downward chip removal, and a round die with a conical locking hole for strong, non-loosening performance.

This metric tap and die set can re-thread damaged or jammed threads or create new threads in mild steels, aluminum, iron, copper, and hard plastic, with a grease-coated surface to prevent rust.

Designed for hand use with a tap wrench and die stock, and it is recommended to apply cutting lubricant or oil during the process for higher thread quality and longer tool life.

For best results, ensure proper alignment, use consistent pressure, and periodically reverse while tapping to break chips and remove debris from the flutes for clean, precise threads.
