Maschio per filettatura a macchina M18x1,5 DIN 374B (6H) HSSE-Co TiN punta elicoidale 800X

Threading through holes in tough materials like stainless steel or alloy steel can quickly dull standard taps, causing breakage, poor thread finish, and costly rework. This M18x1.5 machine tap is engineered to cut clean, accurate metric threads in through holes with high efficiency and extended tool life, thanks to its cobalt-enriched HSSE substrate and TiN coating.

Who is it for

Machinists, metalworking shops, and maintenance professionals who need reliable thread production in steel, stainless steel, cast iron, and non-ferrous metals. It is ideal for CNC machines, machining centres, or manual tapping operations where precision and durability are critical.

Main features

• Thread size M18 with 1.5 mm pitch, metric coarse thread to DIN 374B standard.
• Tolerance class 6H for standard internal thread fit.
• Spiral point (gun nose) geometry pushes chips forward, perfect for through holes.
• HSSE-Co (cobalt high-speed steel) offers superior heat resistance and toughness.
• TiN (Titanium Nitride) coating reduces friction, increases surface hardness, and extends tool life.
• Reinforced shank with 14 mm diameter and 11 mm square drive for secure clamping.
• Lead-in form B with 4-5 threads for easier starting and alignment.
• Ground thread for high accuracy and consistent performance.

Tips

Use a suitable cutting fluid or tapping paste to maximise tool life and thread quality. Ensure the tap is aligned perpendicular to the workpiece. For CNC applications, follow recommended speeds and feeds for HSSE-Co taps in the specific material. Pre-drill the hole to the correct diameter for M18x1.5 (typically 16.5 mm) to achieve proper thread engagement.
