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

Product information

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. What is a spiral-fluted machine tap? A spiral-fluted machine tap has helical flutes running around the cutting section of the tool. During blind-hole tapping, this geometry helps direct chips back towards the hole entrance instead of forcing them further into the hole. The Code 4671 uses a pronounced 40° spiral angle together with Form C chamfer geometry for efficient, controlled machine tapping. Product highlights • Speedtap Universal series: Maykestag high-performance machine tapping range designed for dependable production threading. • M3 x 0.5 metric thread: Produces M3 metric ISO threads with a standard 0.5mm pitch. • DIN 376: Manufactured according to the specified DIN standard for this machine-tap series. • HSSE-V3 cutting material: High-performance high-speed steel grade specified by Maykestag for the Code 4671 range. • 40° spiral flutes: Designed to promote chip evacuation towards the hole entrance during blind-hole tapping. • Blind-hole geometry: Specifically designated by Maykestag for blind-hole threading applications. • Form C chamfer: Short 2–3 pitch chamfer suited to controlled thread production in blind holes. • ISO2 (6H) tolerance: Produces the widely used ISO metric internal-thread tolerance class 6H. • Three-flute design: The M3 tap is manufactured with three cutting flutes. • Recommended tap drill: Maykestag specifies a Ø2.5mm pre-drill diameter for this M3 x 0.5 tap. Why Choose Maykestag? Maykestag is an Austrian cutting-tool specialist with a strong focus on precision drilling, milling, reaming and threading tools for professional machining. Correct geometry, dimensional accuracy and material selection are particularly important in machine tapping, where reliable chip control and consistent thread quality directly affect production efficiency and tool life. The Code 4671 Speedtap Universal series combines HSSE-V3 cutting material, 40° spiral-fluted geometry and a Form C chamfer with precisely defined ISO metric thread tolerances. For this M3 version, Maykestag specifies a 0.5mm pitch, three flutes and a Ø2.5mm tap-drill diameter. 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.
