M16 DIN 376B (6H) HSSE 800 Machine Tap for Through Holes

Cutting M16 threads in tough steel alloys demands a tool that stays sharp and accurate—this HSSE 800 tap delivers exactly that, with a 6H tolerance class ensuring a precise fit every time.

Overview

Built for through-hole threading, this M16 machine tap follows the DIN 376B standard and features a straight flute design that efficiently evacuates chips. The high-speed steel with cobalt (HSSE) construction provides excellent heat resistance and wear resistance, making it suitable for general purpose steel, alloy steel, and non-ferrous metals. A cylindrical shank with square drive ensures secure chucking in machine holders.

What stands out

• M16 coarse thread with 2.0 mm pitch for standard metric fasteners
• 6H tolerance class for medium fit—ideal for general engineering
• HSSE cobalt steel withstands high cutting temperatures
• Straight flutes optimized for through holes, preventing chip clogging
• Uncoated surface allows re-sharpening for extended tool life
