Chip-Clearing Taps for Through Holes
Keep chips clear while tapping. Also known as gun taps, these have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. They're made of high-speed steel for use on most metal and plastic. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. Titanium-carbonitride (TiCN) coated taps have up to three times the tool life of uncoated taps. Their hard, smooth finish offers superior resistance to chipping, wear, and heat.

JIS Thread Taps
Produce metric threads that meet Japanese Industrial Standards. These taps are made of high-speed steel for use on most metal and plastic. They have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.
Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper-chamfer taps. When using them to tap closed-end holes, be sure to leave enough space at the bottom for chips to accumulate.
