Maykestag Speedtap Universal HSSE-V3 Machine Tap M8 x 1.25 Straight Fluted DIN 376

Maykestag Speedtap Universal HSSE-V3 Machine Tap M8 x 1.25

Professional M8 x 1.25 Speedtap Universal machine tap manufactured from HSSE-V3 with straight-fluted geometry for producing metric ISO internal threads to DIN 13. Manufactured to DIN 376 with ISO2 (6H) thread tolerance and a Form B chamfer of 3.5-5 pitches for reliable machine tapping of through holes.

The Maykestag Code 4631 Speedtap Universal is a straight-fluted machine tap developed for machining metric ISO threads. This M8 version has a 1.25mm pitch and is manufactured to DIN 376 dimensional requirements with an ISO2 (6H) thread tolerance. Maykestag specifies the series for through-hole applications with a threading depth of up to 3 x the nominal thread diameter. The combination of HSSE-V3 cutting material, straight flutes and a Form B lead makes it a professional threading tool for controlled, repeatable machine tapping.

What is a straight-fluted machine tap? A straight-fluted machine tap has flutes that run parallel to the axis of the tool rather than following a spiral path. The flutes provide the cutting edges and space required during thread formation. The Maykestag Code 4631 is specifically identified as a Speedtap Universal straight-fluted machine tap for metric ISO threads and is intended for through-hole applications. Product highlights

With threading tools, accurate geometry, thread tolerance, cutting material and dimensional consistency are particularly important because they directly influence thread quality, tool life and repeatability. Maykestag provides clearly defined standards and application data to help users select the correct tap for the machining task.

The Code 4631 Speedtap Universal series combines HSSE-V3 cutting material with straight-fluted geometry, DIN 376 dimensions, metric ISO thread geometry and an ISO2 (6H) tolerance. The M8 model features a 1.25mm pitch, three cutting flutes and a Form B chamfer, providing a precisely specified solution for professional M8 through-hole threading.

Designed for Accurate Metric Threading

The Code 4631 combines straight-fluted cutting geometry with a Form B lead of 3.5-5 pitches to provide progressive cutting engagement as the tap enters the prepared hole. For this M8 model, Maykestag specifies a 6.8mm tap-drill diameter, a 1.25mm thread pitch and an ISO2 (6H) tolerance. Using the correct tap-drill size together with suitable cutting speed, lubrication and machining conditions is essential for producing accurate threads and achieving dependable tool life.
