Maykestag Speedtap-Inox M30 x 3.5 Straight-Fluted Machine Tap
Professional M30 x 3.5 Speedtap-Inox machine tap manufactured from HSSE-V3, featuring straight flutes, four cutting flutes, VAPO surface treatment and Form B chamfer geometry for producing metric ISO through threads. Manufactured to DIN 376 with ISO 2 (6H) thread tolerance.
The Maykestag Code 4612 Speedtap-Inox is a high-performance straight-fluted machine tap for producing metric ISO internal threads according to DIN 13. This M30 version has a 3.50mm pitch and is designed for through-hole tapping, with a Form B chamfer extending over approximately 3.5 to 5 thread pitches. Its HSSE-V3 cutting material, VAPO-treated surface and precision thread geometry make it particularly well suited to demanding professional threading applications, including stainless steels.
Product highlights

Why Choose Maykestag?
Maykestag is an Austrian cutting-tool brand specialising in precision-manufactured drilling, milling and threading tools for professional machining. With threading tools, accurate control of the thread profile, pitch, cutting geometry and tolerance is essential because small dimensional variations can directly affect thread quality, tool life and assembly reliability.
The Code 4612 Speedtap-Inox series combines HSSE-V3 cutting material, straight-fluted geometry, Form B chamfer design and VAPO surface treatment. The range is engineered for metric ISO through-hole threading and carries particularly strong Maykestag application ratings for steels, stainless steels and cast iron.
Designed for Accurate Metric Threading
This M30 Speedtap-Inox tap combines a 3.50mm pitch with a 60° ISO metric thread profile and ISO 2 (6H) tolerance for accurate internal thread production. The Form B chamfer provides gradual cutting engagement, while the four straight flutes support controlled cutting during through-hole tapping. Maykestag specifies an overall tool length of 180mm, a 45mm threaded cutting length, a 22mm shank diameter and an 18mm square drive dimension for this M30 version. When used with the specified 26.5mm tapping-drill diameter and appropriate cutting conditions, the tool is designed for reliable, repeatable machine threading.
