Tap (left-hand) FANAR NARZYNKA M 8x1 DIN-22568 LH HSS 800 Threading Tool M8x1

FANAR NARZYNKA M 8x1 DIN-22568 LH HSS 800 is a left-hand machine tap designed to cut internal M8x1 metric threads. Manufactured from HSS 800 high-speed steel and produced to DIN-22568 tolerances, this tap provides precise, repeatable left-hand threading for production, maintenance and tooling operations where a left-hand orientation is required.

Advantages

The HSS 800 material offers high hardness and wear resistance for extended tool life under standard machining conditions. Conformance to the DIN-22568 specification ensures dimensional accuracy and interchangeability with other metric M8x1 components. The left-hand geometry allows creation of threads used where rotational direction or assembly requirements demand counter-clockwise thread form.

Suitable for

• Cutting internal M8x1 left-hand threads in steel and similar metals
• Production runs and maintenance operations requiring consistent thread quality
• Tooling setups and fixtures that use left-hand fasteners
• Applications where a machine tap is preferred over hand tapping

When it may not be suitable

This tap is specifically a left-hand tool and is not appropriate for standard right-hand thread cutting. It is intended for use in compatible materials and machining setups; very hard, abrasive, or non-metallic materials may require a different grade or coating to avoid premature wear or chipping.

Key specifications

• Thread size and pitch: M8 x 1
• Hand: left-hand thread form
• Material: HSS 800 high-speed steel
• Standard: DIN-22568
• Tolerance class: suitable for 6g fit (as indicated in product naming)
• Intended use: machine tap for internal threads

How to use

Secure the correct tap holder or machine spindle and align the tap accurately with the hole axis before starting. Use appropriate cutting fluid and maintain steady feed to avoid excessive torque. For through-holes, use continuous feed; for blind holes, withdraw periodically to clear chips. Observe recommended spindle speed and feed for HSS tooling and the material being machined, and inspect threads for correct fit after cutting.

What to consider before purchase

• Confirm that M8x1 left-hand threads are required for your assembly or repair.
• Verify material compatibility and whether a coated or different-grade tap is needed for abrasive or hardened workpieces.
• Ensure your machine or tap holder supports left-hand tapping and the required spindle direction.

Usage recommendations

For best results, use light to moderate cutting speeds suitable for HSS 800 and apply appropriate cutting fluid. Clear chips frequently on blind holes and replace the tap at the first sign of wear to maintain thread quality and dimensional accuracy.
