MAYKESTAG Speedtap Universal HSSE-V3 Machine Tap M3 Spiral Fluted DIN 376

Maykestag Speedtap Universal HSSE-V3 Machine Tap M3 Spiral Fluted DIN 376

Professional M3 x 0.5 Speedtap Universal machine tap manufactured from HSSE-V3, with 40° spiral-fluted geometry, Form C chamfer and ISO2 (6H) thread tolerance for accurate metric ISO threading in blind holes.

The Maykestag Code 4671 Speedtap Universal is a spiral-fluted machine tap designed for producing metric ISO threads according to DIN 13. This M3 version has a 0.5mm thread pitch and is manufactured to DIN 376, combining a 40° spiral angle with a short Form C chamfer of 2–3 pitches. The geometry is specifically suited to blind-hole threading, where controlled chip evacuation is particularly important.

Designed for Blind-Hole Machine Tapping

Blind-hole tapping requires effective chip management because chips cannot continue through the bottom of the workpiece. The 40° spiral-fluted geometry of the Speedtap Universal is designed to move chips back towards the entry side of the hole during the tapping operation. Combined with its short Form C chamfer and ISO2 (6H) thread tolerance, the Code 4671 provides a purpose-designed solution for accurate machine production of metric ISO internal threads.
