MF HSSE SUPREME 900X DIN374 B Through-Hole Machine Tap – Koronet

Professional MF Precision Fine Threading Tap

The Koronet SUPREME 900X machine tap is a premium tool designed for precision metric fine-turn threads in structural steels, alloy steels and high-strength materials.
Made of high-quality high-speed HSSE steel and equipped with an AlCrN coating, it ensures a stable cutting process, high wear resistance and a significantly longer service life compared to typical TiN/TiCN coated taps.

Product highlights

• High-quality HSSE steel – stability and strength

The core of the tool is made of improved high-speed HSSE steel, providing:

• high resistance to torsional loads,

• stability of operation in steels with higher hardness,

• Reduced risk of chipping when threading materials that are more difficult to process.

It is a material of choice where repeatability and reliability are important.

• AlCrN coating – premium class of the SUPREME 900X series

An advanced coating from the AlCrN group provides:

• very high abrasion resistance,

• increased thermal stability,

• reduction of material adhesion and build-up,

• significantly longer service life than TiN/TiCN coatings.

This allows the tool to work at higher parameters and better withstands threading of more difficult steel grades.

DIN 374 standard – tap for MF (fine-turned) threads

Tool made in accordance with DIN 374, typical for MF (Metric Fine – metric fine-thread)
This standard provides:

• an elongated working part,

• slimmer geometry beneficial for precision machining,

• high standard of workmanship ensuring thread repeatability.

Type B – cut 4-5 coils

Geometry B enables:

• smooth tap entry into the material,

• stable thread forming on the full length,

• Optimal guidance in through-holes.

It is the most universal typeface used in workshop and industrial production.

Straight grooves – for through-holes

Straight grooves provide:

• linear tool guidance,

• effective chip evacuation straight ahead,

• Stable, controlled operation when tapping through holes in steel.

The Koronet SUPREME 900X MF10×1.0 tap is designed for machining:

• structural and unalloyed steels,

• alloy steels,

• heat-treated steels,

• materials with increased strength,

• materials that tend to grow.

Recommended for work:

• on CNC machine tools,

• in precision heads of conventional machines.

Ideal where high tool life, process stability and repeatable MF thread quality are required.
