Tap FANAR GWINTOWNIK M16 DIN-376C LH (6H) HSSE 800 - left-hand M16 threading

FANAR GWINTOWNIK M16 DIN-376C LH (6H) HSSE 800 is a left-hand machine tap designed to cut M16 threads to the DIN 376C profile. Manufactured from HSSE 800 high-speed steel with added cobalt, this tap is intended for industrial and workshop tapping operations where left-hand threads and precision 6H tolerance are required. The tool is compatible with common steels and many alloy materials and is intended for use in machine tapping applications.

Advantages

The HSSE 800 material with cobalt increases wear resistance and thermal stability, extending tool life during repetitive machine tapping. The DIN 376C geometry delivers a standardized thread form and reliable 6H tolerance, ensuring interchangeability and accurate fits. Left-hand cutting simplifies production of components that require opposite-thread connections or where conventional right-hand taps would be unsuitable.

Suitable for

• Machine tapping of M16 left-hand threads
• Tapping operations in steel and alloy materials
• Production and repair of components with left-hand fasteners
• Workshop and industrial machining centers

Key specifications

• Thread size: M16 (left-hand)
• Thread form: DIN 376C
• Tolerance class: 6H
• Material: HSSE 800 (high-speed steel with cobalt)
• Intended use: machine tap for internal threads

How to use

Secure the workpiece and ensure proper alignment of the tap with the hole axis before starting the operation. Use the correct drill size and prepare the hole according to DIN 376C recommendations. Apply appropriate cutting fluid for the material being tapped to improve chip evacuation and reduce wear. Operate the tap in the machine at recommended spindle speeds and feed rates for M16 threads and the workpiece material, reversing the rotation to break chips as needed.

Usage recommendations

To maximize tool life and thread quality, select cutting parameters matched to the workpiece material, use steady machine feed, maintain coolant flow, and inspect taps periodically for wear or chipping. For challenging alloys, reduce speed and increase coolant. Replace the tap when thread quality declines or visible wear appears.
