MAYKESTAG Speedtap-Inox HSSE-V3 Machine Tap M3 x 0.5 Straight Fluted DIN 376 VAPO

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.
• 60° metric thread profile: Correct profile for metric ISO threads according to DIN 13.
• Through-hole tapping: Maykestag specifies the series for through-hole applications with a threading depth of up to 3 x d1.
• 2.5mm tap-drill size: Maykestag specifies a Ø2.5mm preparation hole for this M3 x 0.5 tap.

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.
