Tap FANAR M16 DIN 376C L40 Left-hand (6H) HSSE 800 - model D2-591101-0160

Tap FANAR M16 DIN 376C L40 Left-hand (6H) HSSE 800 - model D2-591101-0160 is a precision threading tap designed to produce internal M16 left-hand threads in accordance with DIN 376C. The tool has an overall length of 40 mm and a 6H tolerance class to ensure accurate fit and interchangeability. Manufactured from HSSE 800 high-speed steel with enhanced alloying, the tap provides improved wear resistance and toughness for thread production in a range of ferrous and non-ferrous materials.

Advantages

The HSSE 800 material composition increases cutting-edge hardness and extends tool life under cyclic cutting conditions. The DIN 376C geometry ensures consistent thread form and alignment, while the 6H tolerance class offers reliable mating with standard bolts and components. Left-hand thread configuration allows threading of components where reverse rotation or counter-threaded assemblies are required. The compact L40 length provides good rigidity for hand-held and machine tapping operations.

Suitable for

• Producing M16 left-hand internal threads in through holes and blind holes
• Machine shop threading operations on steels, stainless steels, and non-ferrous alloys
• Maintenance and repair tasks requiring replacement or creation of left-hand threads
• Precision assembly work where 6H tolerance class is specified

Key specifications

• Thread size: M16 (metric)
• Thread standard and profile: DIN 376C
• Thread direction: left-hand
• Tolerance class: 6H
• Overall length: 40 mm
• Material: HSSE 800 high-speed steel
• Intended use: Through and blind hole tapping

How to use

Secure the workpiece and select the correct pilot drill diameter and hole depth for M16 threads according to DIN recommendations. Mount the tap in a compatible holder or machine spindle ensuring axial alignment. Use appropriate cutting fluid to reduce heat and improve chip evacuation when tapping metals. For blind holes, ensure adequate chip clearance by backing off the tap periodically. Apply steady feed and the correct rotational direction for left-hand threading; reverse the spindle direction compared to right-hand taps.

Usage recommendations

For best results, use this FANAR HSSE 800 tap with controlled spindle speed and steady feed rates suited to the workpiece material. Regularly inspect for wear and maintain correct lubrication to prolong tool life. When tapping stainless steels or tough alloys, reduce cutting speed and increase coolant to minimise work hardening and improve thread quality.
