Machine Taps M for Through Holes and Blind Holes

When cutting threads, the choice of tool is always determined by the requirements of the respective application area. Our machine taps M are suitable for metric ISO threads. There are differences when cutting threads in through holes versus blind holes. While the machine tap must remove chips above the bore in the case of blind holes, chip removal below the core bore is also not a problem with through holes. Therefore, please pay attention when ordering to whether you need a machine tap M for blind holes or through holes. In principle, our machine taps are designed as single-cut taps, which means that an ISO thread M can be cut in a single operation without the need for multiple tools or steps.

Metric ISO Threads and Other Thread Types

Although the machine taps marked with the letter M are produced for metric threads according to ISO standards, many international thread types can also be cut with them, provided they have a flank angle of 60 degrees. Thus, theoretically, you could use a machine tap made to US standards to cut an ISO-compatible thread and vice versa. However, in this case, you must pay attention to the correct conversion between inches and metric measurements. For reasons of diligence and to avoid conversion errors, we generally recommend that our customers use the correct machine taps M for ISO threads. The specifications are defined in DIN 13 and include, among other things:

• Pitch and thread diameter
• Shank and flank angle
• Tolerance field

Time-Saving Work with Machine Taps M

In our range, you will find a wide selection of various taps for common thread types. If you require special sizes or coatings, please contact us directly. We can find practical and cost-effective solutions for almost all requirements. Our machine taps M are also available in HSSE versions. Unlike conventional HSS (High-Speed Steel) versions, HSSE tools are made with a 5% cobalt alloy, allowing for longer tool life and the ability to machine materials with higher strength. Our MGB taps are not only suitable for steel in various alloys and strength classes but also for other metals like aluminum, bronze, or brass. Additionally, they can cut precise threads in many plastics. To avoid premature wear, many tools can be equipped with a special coating. Furthermore, we can often restore blunt cutting tools to an excellent condition through professional regrinding, thereby extending their lifespan.
