Thread Tap Set Art-Pol M3 x 0.50 mm, metric taps, 3-piece set

Art-Pol thread tap set for cutting internal metric threads M3 x 0.50 mm. This three-piece kit contains taps intended for forming or repairing M3 fine-pitch internal threads in metal and other machinable materials. The set is suitable for both manual and machine tapping operations where a standardized M3 x 0.50 metric thread is required during assembly, repair or maintenance work.

Advantages

The set includes progressive tap types that allow staged cutting from initial chamfer to full-profile thread, reducing the risk of breakage and improving thread accuracy. Hardened and ground working surfaces provide wear resistance and consistent cutting performance. Compact three-piece packaging ensures all necessary taps for thread success are available in one kit, simplifying tool selection for technicians and hobbyists.

Suitable for

• Cutting new M3 x 0.50 internal threads in metal components
• Repairing damaged or worn M3 threads
• Manual hand-tapping with tap wrench
• Machine tapping in small parts or jigs
• Electronics assembly, fittings and small mechanical assemblies

Key specifications

• Thread size: M3 x 0.50 mm
• Set composition: three taps with progressive chamfers (starter, intermediate, plug/finishing)
• Material: hardened and ground steel suitable for machining metals and common machinable materials
• Intended use: internal metric fine-pitch thread cutting and repair
• Application method: manual or machine tapping

How to use

Secure the workpiece and ensure the hole diameter matches the recommended drill size for an M3 x 0.50 internal thread. Use a suitable tap wrench for manual tapping or install the tap in a tapping head for machine operations. Apply appropriate cutting fluid to reduce friction and aid chip evacuation. Start with the first tap (starter) and rotate evenly, backing off periodically to clear chips, then proceed with the intermediate tap and finish with the plug/finishing tap to achieve the full thread profile. Clear chips from the hole between passes and inspect the thread for proper fit.

Usage recommendations

Use correct drill size and steady alignment to prevent cross-threading. Apply cutting fluid for metal work and remove chips frequently. Select manual or machine tapping depending on part accessibility and production needs, and avoid excessive torque to reduce tap breakage.
