M16 x 1 mm Macho de roscar manual de rosca fina, macho de roscar para furo, DIN 2181, tolerância 6H, revestimento EL-CUT

In a busy machine shop, a technician picks up this M16 x 1 mm fine pitch hand tap to cut clean internal threads in a steel bracket. The EL-CUT coating reduces friction, so the tap glides through the material while producing accurate 6H tolerance threads. This plug tap is the second in a set, ideal for threading through-holes after the taper tap has started the thread.

Key specifications

• Thread size: M16 x 1 mm (fine pitch)
• Tap type: Hand tap, plug tap (second tap in a set)
• Standard: DIN 2181
• Tolerance class: 6H
• Material: High-speed steel (HSS)
• Coating: EL-CUT (friction-reducing)
• Thread direction: Right-hand
• Shank: Square drive

Why choose it

The EL-CUT coating significantly reduces cutting forces and heat, extending tool life and improving thread quality. The fine pitch (1 mm) provides a larger minor diameter, making it suitable for thin-walled components or applications requiring higher strength. The 6H tolerance ensures compatibility with standard metric fasteners, and the HSS construction offers a good balance of toughness and wear resistance for manual threading.

Ideal use cases

• Creating or repairing M16 x 1 mm threads in steel, cast iron, and non-ferrous metals
• Manual thread cutting in maintenance, repair, and prototyping
• Through-hole threading where a plug tap is appropriate
• Applications requiring fine pitch threads for precision adjustment or higher strength

Good to know

For best results, use a suitable cutting fluid and ensure the tap is aligned perpendicular to the workpiece. This tap is part of a set; for blind holes, a bottoming tap may be needed after the plug tap. Always follow recommended cutting speeds and use a tap wrench with a square drive.
