"M" - Through hole

Through Hole Machine Taps for ISO Thread M

The through hole differs from the blind hole not only by the obvious characteristic that the bore runs completely through the workpiece being processed. There are also differences when you want to cut a thread. While with the through hole, machine taps M can remove chips both upwards and downwards, with a blind hole, chip removal is only possible upwards. Therefore, you need to check before cutting the thread whether you need a through hole machine tap or a blind hole tap. In general, the machine taps HSSE in our range are designed as single-cut taps, allowing metric ISO threads M to be produced in a single operation.

Easy Handling for ISO Thread M

All thread types are manufactured according to specific international specifications. While different standards are used in Great Britain and the USA, metric ISO threads are widely regarded as the standard in Germany and large parts of Europe. Please note when selecting that through hole machine taps marked with the letter M are not suitable for cutting fine threads denoted by the abbreviation MF. Although they also have a flank angle of 60 degrees, they have a different pitch that is not compatible with standard threads. The situation is different for inch threads (such as those according to US standards), which can generally be cut with a through hole machine tap for ISO thread M due to their identical flank angles and pitches. However, errors often occur during the conversion from millimeters to inch sizes, which can render an entire manufacturing batch unusable. Therefore, it is advisable to purchase the appropriate thread cutters from our extensive range for each thread type. If you are missing a specific size, please inquire directly about special sizes or custom designs. We offer a wide variety of additional services, including:

• Special coatings
• Regrinding of tools (including those from other manufacturers)
• Customized solutions for special projects

Through Hole Machine Taps M for Left-Hand and Right-Hand Threads

The orientation for left-hand or right-hand threads depends on the type of application when cutting threads. Generally, right-hand threads are cut in industry and crafts. However, if you require left-hand threads due to certain circumstances, please ensure that your through hole machine tap M is suitable for the desired thread orientation when placing your order.
