Mte HSS E DIN 374/C Metric Machine Tap M14x1.5 H6

Mte HSS-E DIN 374/C Metric Machine Tap M14x1.5 H6

High Precision and Strength in Small Diameter Fine Thread Connections

The Mte HSS-E DIN 374/C Metric Machine Tap M14x1.5 H6 is a high-precision and high-performance cutting tool designed for standard Metric Fine Thread tapping operations. This tap is specifically optimized for machine tapping operations (CNC, lathe, or tapping machines), ensuring serial and superior quality production. The M14x1.5 size refers to a fine thread standard with a nominal diameter of 14 mm and a pitch of 1.5 mm.

The product's core strength comes from its HSS-E (Cobalt Alloyed High-Speed Steel) material, which offers superior cutting performance and long life even in hard and difficult-to-machine materials. Furthermore, the DIN 374/C standard and H6 tolerance guarantee that the tapped thread will have the highest quality in terms of precision and fit.

Product Features and Material Details

This machine tap offers high speed, long life, and the tightest tolerances for critical fine metric thread connections.

Feature Name	Detailed Description
Thread Type	Metric Fine Thread (MF): M14x1.5 (14 mm diameter, 1.5 mm pitch). Provides more contact surface compared to standard threads, offering advantages in vibration resistance and sealing.
Size	M14x1.5
Standard	DIN 374/C: An internationally recognized German standard for metric fine threads. The 'C' form indicates suitability for machine use with single-pass tapping and a short lead taper.
Tolerance	H6: Specifies the tolerance class of the internal diameter of the thread produced by the tap. H6 is the tightest tolerance class, used for very precise and tight connections.
Material Type	HSS-E (Cobalt Alloyed High-Speed Steel): The Cobalt (5%) alloy increases resistance to high temperatures, cutting speed, and tool life. It is excellent especially for stainless steels (INOX) and difficult-to-machine steels.
Flute Type	Usually Straight Fluted.
Recommended Pilot Hole	A pilot hole with a diameter of generally 12.50 mm is recommended for tapping M14x1.5 threads.

User Information and Benefits

This product caters to professional users seeking high precision, long life, and serial production capability even in challenging materials:

Maximum Tool Life: The HSS-E (Cobalt) alloy increases the tap's wear resistance and extends its life, even at high cutting speeds, especially in hard materials like stainless steel.

Superior Precision: The H6 tolerance ensures that the produced thread is within the tightest limits, guaranteeing perfect fit, strength, and sealing of connection elements.

Vibration and Sealing Advantage: Fine thread (1.5 mm pitch) offers more contact surface than standard threads, which reduces the risk of loosening under vibration and provides better sealing.

High Efficiency: Its suitability for machine use saves time and cost in serial production.

Versatile Material Compatibility: Thanks to its cobalt content, it offers high performance in a wide range of materials, even in difficult-to-machine ones.
