HSSE-V3 Speedtap Universal Machine Tap M8 X 1.25 Spiral Flute Din 376 Vapo

Features

Description

Maykestag HSSE-V3 Speedtap Universal Machine Tap M8 x 1.25 Professional M8 x 1.25 Speedtap Universal machine tap manufactured from HSSE-V3 cobalt high-speed steel, featuring a 40° spiral flute, Form C chamfer, ISO 2 (6H) thread tolerance and VAPO surface treatment for accurate blind-hole threading in steels up to 850 N/mm².

The Maykestag Code 4611 is a high-performance spiral-fluted machine tap designed for producing metric ISO internal threads to DIN 13. Its 40° spiral flute geometry directs chips back towards the entrance of the hole, making the tap particularly suitable for blind-hole threading where effective chip evacuation is important.

Manufactured to DIN 376 and designed for thread depths up to 2.5 times the nominal diameter, the Speedtap Universal combines controlled chip removal, accurate thread production and dependable performance in suitable non-alloyed and alloyed steels. What is a spiral-flute machine tap? A spiral-flute machine tap uses helical flutes to transport chips backwards and out of the hole while the thread is being cut.

This makes the geometry particularly effective for blind holes, where chips cannot simply be pushed ahead of the tool. The 40° spiral angle of the Code 4611 assists chip evacuation while the Form C chamfer gradually introduces the cutting teeth into the workpiece for controlled thread formation. Product highlights

• HSSE-V3 tool material: Cobalt-alloyed high-speed steel provides the toughness, heat resistance and cutting-edge durability required for professional machine tapping.
• M8 x 1.25 metric thread: Produces standard M8 coarse-pitch metric ISO internal threads with a 1.25mm pitch.
• 40° spiral flute: Helical flute geometry directs chips towards the hole entrance for effective evacuation during blind-hole tapping.
• Blind-hole design: Suitable for thread depths up to 2.5 x the nominal thread diameter under appropriate machining conditions.
• Form C chamfer: 2-3 pitch chamfer provides a controlled cutting entry suited to blind-hole applications.
• ISO 2 (6H) tolerance: Designed to produce commonly specified 6H tolerance metric internal threads.
• VAPO surface treatment: Maykestag VAPO-treated cutting surface for professional tapping applications.
• DIN 376: Manufactured to the dimensional standard specified for this machine-tap series.
• Three-flute geometry: Z = 3 cutting-flute configuration.
• 6.8mm tap drill: Recommended pre-drill diameter for the M8 x 1.25 thread size.

Why Choose Maykestag?

Maykestag is an Austrian cutting-tool brand focused on precision-manufactured tools for professional machining. With threading tools, accurate geometry, reliable dimensional tolerances and effective chip control are essential because even small deviations can affect thread quality, tool life and process reliability.

Maykestag machine taps are developed around clearly specified thread standards, cutting materials and application data to help professional users select the correct tool for the job. The Code 4611 Speedtap Universal series combines HSSE-V3 tool material with a 40° spiral flute, Form C chamfer and VAPO surface treatment for blind-hole threading.

It is particularly suited to non-alloyed and alloyed steels up to 850 N/mm², providing a dependable solution for workshops, toolrooms and production environments requiring consistent metric internal threads. Designed for Controlled Blind-Hole Threading The 40° spiral flute is designed to move chips upwards and away from the cutting zone as the tap advances into a blind hole.

This reduces chip accumulation at the bottom of the hole and supports consistent thread formation. The Form C 2-3 pitch chamfer provides a relatively short cutting lead suited to blind-h
