Description

Machine Tap DIN 374 Form C 35° Spiral Flute HSSE - M 40 x 1.5

Use Machine Tap DIN 374 Form C 35° Spiral Flute HSSE - M 40 x 1.5 for internal thread cutting in common metalworking operations where tool guidance and chip evacuation matter. The spiral flute supports chip transport out of the hole during tapping.

Selection is driven by thread standard, material group, and the flute geometry shown in the product name, especially when you work in blind holes.

Application

Cut internal threads in predrilled holes in mechanical engineering, maintenance, and metal fabrication.
Use for ISO metric threads as designated in the product name.
Prefer for blind holes where chip transport out of the hole is required.
Use a machine tap holder or tapping chuck that clamps the shank securely and supports straight entry.
Process: manual driving or assisted driving depending on your holder and machine setup
Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Verify the exact designation, standard, and tolerance in the product name before you start.

Benefits

Suitable for repeatable workflows in maintenance and serial production setups.
Efficient chip transport supported by flute design when correct cutting fluid is used.
Simple inspection using a suitable screw or gauge after cleaning the thread.
Consistent internal thread geometry when the tool is guided square to the surface.
Spiral flute supports chip evacuation from blind holes and reduces jamming risk.

Drawbacks

Not suitable for hard to machine materials without defined cutting data and stable machine rigidity.
Not intended for high output production where dedicated high performance tooling is required.

Step by step

Confirm the thread designation in the product name matches the drawing and the mating screw.
Prepare a suitable predrilled hole and deburr the entry for clean lead in.
Clamp the tap in a stable machine tap holder or tapping chuck.
Align the spindle square to the surface so the tap starts without side load.
Apply suitable cutting fluid and start tapping with steady feed.
Monitor chip evacuation and reverse out to clear chips if resistance increases.
Back out completely and flush the thread to remove chips and fluid residues.
Inspect the result with a suitable screw or gauge before assembly.

Frequently asked questions (FAQ)

How do you select the correct variant for your drawing Match the thread designation in the product name to the drawing and the mating fastener. Confirm thread series, pitch, and class of fit before you start, especially for inch based threads. Is this tap suitable for blind holes or through holes The suitability depends on flute geometry and lead form noted in the product name. Spiral flute execution is typically chosen for blind holes because chips are transported out of the hole. Where can you find technical background information for this tap type Use this PDF for technical notes, application limits, and terminology. Technical information machine taps as PDF Which tolerance class do you typically achieve The typical tolerance class for this execution is ISO 2 (6H) when the process is set up correctly and the hole preparation matches the thread system. Do you need cutting fluid Yes, use suitable cutting fluid for the material to reduce friction and control chip formation. Keep lubrication consistent from start to finish and clean the tool after use. Which holder should you use Use a holder that clamps the shank securely and supports straight entry. In manual work this is typically a tap wrench, and in machines a tapping chuck or a suitable collet holder.
