Precision Twist Drill Straight Flute Machine Tap, Series: E504, Measurement System: Metric, Coarse Thread Standard, M12x1.75 Thread, Bottoming Chamfer, 3 Flutes, HSS, TiN Coated, Class of Fit: 6H, Right Hand Cutting Direction, 22 mm Thread Length, 89 mm Overall Length, 9 mm Shank Diameter

• Designed for through or blind hole tapping with a specific cutting geometry for gray cast irons and those materials producing broken chips
• Also ideal for non-metallics, cast brass, and other brass materials producing broken powdery chips
• TiN coating increases the surface hardness and improves tool life
• Titanium nitride is a gold colored ceramic coating applied by physical vapor deposition (PVD)
• High hardness combined with low friction properties ensures considerably longer tool life, or alternatively, better cutting performance from tools which have not been coated
• TiN coating is used mainly for drills and taps
• A medium alloyed high speed steel that has good machinability and good performance
• HSS exhibits hardness, toughness and wear resistance characteristics that make it attractive in a wide range of applications
