Tap set Art-Pol M9 x 0.75 mm, 2-piece (threading taps)

Art-Pol tap set for cutting internal metric threads M9 x 0.75 mm. The two-piece set contains the necessary taps for producing and restoring internal threads with a 0.75 mm pitch in metal and other machinable materials. Designed for workshop use and maintenance, the set is intended to create accurate mating threads in components, housings, fastener holes and repair tasks where this metric size is required.

Advantages

The two-piece configuration covers the typical sequence for thread forming and finishing, allowing controlled chip evacuation and more consistent thread geometry. Precision-ground flutes and hardened tool steel construction provide wear resistance and dimensional stability during repeated use. The set is compact, easy to store, and compatible with standard tapping handles or holders designed for hand or machine tapping operations.

Suitable for

• Cutting or restoring internal metric M9 × 0.75 threads in metal parts
• Workshop repair and maintenance of machinery components
• Creating threaded holes in housings, brackets and fixtures
• Prototyping and small-series production where metric fine threads are required

Key specifications

• Thread form: metric fine pitch
• Thread size: M9 × 0.75 pitch
• Set composition: 2 taps (progressive roughing and finishing sequence)
• Material: hardened tool steel suitable for metalworking
• Flute type: spiral/straight flutes for chip evacuation (as marked by the manufacturer)

How to use

Choose the appropriate tap from the set and secure the workpiece. Drill the pilot hole to the correct diameter recommended for M9 × 0.75 internal threads, clamp the part, apply suitable cutting fluid, and align the tap perpendicular to the hole axis. Start tapping by turning the tap slowly clockwise, advancing a partial turn then reversing slightly to break chips. Progress through the sequence from the roughing/preliminary tap to the finishing tap to achieve clean, accurate threads. After tapping, clear chips from the hole and inspect thread fit with the mating screw or gauge.

Usage recommendations

Use appropriate cutting fluid for the work material, maintain correct pilot hole diameter, and avoid excessive force to reduce tap breakage. For blind holes, retract frequently to clear chips; for through holes, ensure adequate chip exit. Store taps dry and protected to preserve cutting edges.
