Drill America #19 Tin-Coated Drill Bit (Pack of 12), DWDTN Series

Superhard titanium nitride surface treatment improves drill life, chip ejection, and productivity; decreases horsepower requirements. Ideal for hard metals, work hardened stainless and other difficult to drill materials.

• High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
• Titanium nitride coatings add a hard layer of gold-colored ceramic to the surface that extends tool life and permits faster cutting speeds than uncoated tools
• Round shanks allow use with a wide variety of toolholding systems
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• Ideal for hard metals, work hardened stainless and other difficult to drill materials
