Tap (gwintownik) FANAR M 1.6 DIN-371B (6H) HSSE‑PM HL MASTERTAP

FANAR M 1.6 DIN-371B (6H) HSSE‑PM HL MASTERTAP is a machine tap engineered for cutting metric M1.6 threads with precision. Conforming to DIN 371B geometry and 6H tolerance class, this tap is manufactured from HSSE‑PM (high-speed steel produced by powder metallurgy) to provide consistent hardness and improved wear resistance. The HL surface finish enhances chip evacuation and reduces friction during tapping operations, making it suitable for small-diameter thread production in industrial and workshop environments.

Advantages

This FANAR machine tap offers high material uniformity and wear resistance due to HSSE‑PM construction, which supports longer tool life and stable cutting performance when machining small threads. The DIN-371B profile and 6H tolerance ensure thread accuracy and interchangeability with standard metric fasteners. The HL surface treatment improves lubricity and chip flow, reducing the risk of tool clogging and breakage in through and blind holes.

Suitable for

• Precision thread cutting of M1.6 metric threads in metal parts
• Toolroom and fixture production requiring consistent thread tolerances
• Serial production and small-batch machining of electronic and miniature components
• Tapping in through-holes and controlled blind holes with appropriate machining parameters

Key specifications

• Thread size: M1.6
• Thread form and pitch conformity: DIN 371B
• Tolerance class: 6H
• Material: HSSE‑PM (powder metallurgy high-speed steel)
• Surface finish: HL (improved lubricity and chip evacuation)
• Tool type: machine tap for metric threads

How to use

Select appropriate tap holders or collets for machine tapping operations and secure the FANAR M 1.6 tap straight to avoid side loading. Use recommended spindle speeds and feed for small-diameter HSSE‑PM taps, and apply suitable cutting fluid or lubricant to improve chip evacuation and reduce wear. For blind holes, retract periodically to clear chips; for through-holes, ensure a clear exit to avoid excessive back pressure. Monitor tool condition and replace the tap when wear or damage affects thread quality.

Usage recommendations

Use peck tapping cycles or programmed retracts when machining blind holes, maintain rigid setup to minimize runout, and match cutting speed and feed to the workpiece material—softer materials generally allow higher speeds, while harder alloys require reduced speeds and increased lubrication. Inspect threads after tapping for dimensional compliance with 6H tolerance.
