Description
KEO NC spotting drills are designed with a narrow chisel edge for quick star ting and a constant web to allow for resharpening without the need for web thinning. 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. Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction.
