This tap bit supports internal threading with compact drives such as bit holders and reversible drills, where access is limited.
Check that your hole preparation and holder setup match the tool style, since misalignment is a common cause of poor thread quality. M denotes ISO metric thread designation used for common metric screw threads in machine building and maintenance. HSS-G indicates a ground high speed steel tool, typically selected when edge definition and repeatability matter.
Note Align the tool to the hole axis and avoid forcing, since torque spikes can damage the thread flanks.
