M11 x 1mm Thread Repair Set
This kit supplies one HSS machine tap and one alloy tool steel round die for creating or restoring M11 x 1mm metric threads. It suits maintenance technicians and machinists who need to produce clean male and female threads in workshop or repair tasks. The tools are designed for right-hand threads only.
Manual and Machine Operation
The tap has an 80mm overall length, 23mm thread length and 6mm square shank, allowing use on drill presses, tapping machines, CNC and milling machines. The round die measures 30mm outside diameter and 8mm thickness for use with a separate die wrench. Both components are made from wear-resistant materials for extended service life.
Material Performance on Common Metals
High-speed steel tap and alloy tool steel die handle alloy steel, die steel, cast iron, and ferrous and non-ferrous materials without premature dulling. The H2 tolerance grade ensures accurate thread form for reliable fastener engagement. A die wrench is not included and must be sourced separately.

Questions about this item
How do I install the M11 x 1mm machine tap on a drill press, and what step is often missed?
Fit the 6 mm square shank into the chuck, align the tap perpendicular to the hole, and use cutting fluid; the step often missed is starting the tap by hand to ensure the first threads are straight before applying machine power.
When will the HSS tap or alloy tool steel die need replacement?
Replace the tap when the 4 flutes show rounded edges or the H2 tolerance threads no longer gauge correctly; replace the 30 mm OD die when the 8 mm thick cutting face dulls and produces torn rather than clean threads.
What limit appears first during sustained threading of alloy steel with this set?
Heat buildup in the high speed steel tap causes loss of hardness faster than the alloy tool steel die wears, so cutting speed must be reduced and coolant applied continuously to maintain thread quality.
