Thread Tap FANAR M12 x 1.25 DIN 374B (6H) HSS-E TiN, right-hand

FANAR thread tap M12 x 1.25 DIN 374B (6H) HSS-E TiN, right-hand is a machine tap manufactured to DIN 374B tolerance for cutting internal metric threads M12×1.25. Made from high-speed steel with cobalt (HSS-E) and finished with a titanium nitride (TiN) coating, this right-hand tap is intended for mechanical tapping in medium-hard metals and general-purpose production and repair environments.

Advantages

The HSS-E material provides improved heat resistance and toughness compared with conventional high-speed steel, while the TiN coating reduces friction and increases surface hardness, extending tool life. The DIN 374B (6H) tolerance ensures consistent thread fit and interchangeability, and the right-hand design matches standard threading direction. The build is suitable for machine tapping operations, offering stability and repeatable performance in serial production and maintenance tasks.

Suitable for

• Cutting internal M12×1.25 threads in medium-hard metals
• Machine tapping in production lines and workshops
• Repair and maintenance of mechanical assemblies with metric thread requirements
• Applications requiring wear-resistant coated taps for longer life

Key specifications

• Thread size: M12 × 1.25
• Tolerance standard: DIN 374B (6H)
• Material: HSS-E (high-speed steel with cobalt)
• Coating: TiN (titanium nitride)
• Hand: right-hand threading
• Application: machine tap for internal threads

How to use

Mount the tap in a suitable machine holder or tapping head that provides axial alignment and rigidity. Use appropriate cutting fluid or coolant to reduce heat and flush chips when tapping medium-hard metals. Feed at the correct spindle speed and axial feed for the material and thread pitch to avoid excessive wear or breakage. Retract the tap periodically to clear chips during through or blind hole tapping and inspect thread quality after machining.

Usage recommendations

For best results, select cutting speeds and feeds recommended for HSS-E taps and the specific workpiece material, maintain rigid setup, and use proper chip evacuation and lubrication. Replace the tap when wear or coating degradation affects thread quality to maintain DIN 374B tolerance and part interchangeability.
