Tap - 2-56 Type 23 HSS Taper Straight Flute
Tap - 2-56 Type 23 HSS Taper Straight Flute - TiN Coating
The most common style of tap
Versatile taps for use in general machine tapping or CNC tapping application
TiN coating increases wear resistance by producing a higher surface harness and exceptional lubricity resulting in longer tool life
Low temperature stress relief that enhances lubricity, reduces friction and increases tap toughness
Use a #51 bit to drill the hole you want to tap. You may want to drill a slightly larger hole in difficult to to tap materials like titanium. This will reduce the chance of your tap breaking and the titanium will still be strong enough to hold the shallower threads.
