Maykestag Speedtap-Inox M3 x 0.5 Straight-Fluted Machine Tap
Professional M3 x 0.5 Speedtap-Inox machine tap manufactured from HSSE-V3, featuring straight flutes, three 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 M3 version has a 0.50mm 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
- Speedtap-Inox series: Maykestag high-performance threading tool designed for professional machine tapping applications.
- M3 x 0.5 metric thread: Produces M3 metric ISO internal threads with a standard 0.50mm pitch.
- Straight-fluted geometry: Designed for efficient through-hole tapping with chips directed ahead of the cutting action.
- Three cutting flutes: The M3 size uses three flutes for controlled cutting and accurate thread formation.
- Form B chamfer: 3.5-5 pitch lead chamfer provides progressive cutting engagement for through-hole applications.
- DIN 376: Manufactured to the dimensional standard specified by Maykestag for this machine-tap series.
- ISO 2 (6H) tolerance: Produces a standard metric internal thread tolerance class suitable for general engineering applications.
- HSSE-V3 cutting material: High-performance alloyed high-speed steel selected for demanding threading operations.
- VAPO surface treatment: Vapour-treated surface designed to assist lubrication and reduce material adhesion during tapping.

- 2.5mm tap-drill size: Maykestag specifies a Ø2.5mm preparation hole for this M3 x 0.5 tap.
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 M3 Speedtap-Inox tap combines a 0.50mm 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 three straight flutes provide the chip space required during through-hole tapping. Maykestag specifies an overall tool length of 56mm, an 11mm threaded cutting length and a 2.2mm shank diameter for this M3 version. When used with the specified 2.5mm tapping-drill diameter and appropriate cutting conditions, the tool is designed for reliable, repeatable machine threading.
