Thread tap FANAR GWINTOWNIK M16x1.5 DIN-374B (6H) HSS-E TiN 800X

FANAR GWINTOWNIK M16x1.5 DIN-374B (6H) HSS-E TiN 800X is a precision thread tap designed for producing internal metric threads M16×1.5 to DIN 374B tolerance class 6H. Manufactured from high-speed steel with cobalt (HSS-E) and finished with a titanium nitride (TiN) coating, this tap combines hardness and heat resistance for stable performance in demanding machining environments. The tool is intended for cutting or forming internal threads in workshop and industrial settings where consistent dimensional accuracy is required.

Advantages

The HSS-E substrate improves hot hardness and toughness compared with conventional high-speed steels, extending tool life when machining tougher materials. The TiN coating reduces friction and increases wear resistance, helping to maintain thread quality and surface finish over longer production runs. The DIN 374B geometry ensures threads conform to standard tolerances (6H), supporting interchangeability and accurate assembly.

Suitable for

• Creating internal M16×1.5 metric threads in component manufacturing
• Use in toolrooms and maintenance workshops for repair and prototyping
• Machining medium to medium‑high strength steels and alloyed materials within manufacturer recommendations
• Batch production where consistent thread tolerance and repeatability are required

Key specifications

• Thread size and pitch: M16 × 1.5
• Tolerance class: DIN 374B (6H)
• Material: High-speed steel with cobalt (HSS‑E)
• Coating: Titanium nitride (TiN)
• Suitable operation: Cutting/forming internal threads

How to use

Select appropriate pilot drilling size and ensure the workpiece is securely clamped and aligned. Use steady feed and correct spindle speed consistent with HSS‑E tooling recommendations and the workpiece material; apply suitable cutting fluid to reduce heat and improve chip evacuation if cutting operations are performed. Engage the tap carefully, maintain axial alignment, and advance with consistent pressure; withdraw periodically to break and clear chips. Inspect threaded hole for conformity to required tolerance after tapping.

Usage recommendations

Use the tap within the manufacturer's recommended material range and cutting parameters. For best results, employ rigid fixturing, correct pilot hole size, and appropriate lubricant. Replace the tap when wear or damaged cutting edges compromise thread quality to maintain dimensional accuracy and avoid workpiece damage.
