Norseman-Viking Ultra Bit Multi-Diameter Set - Step Drills
Electricians Set - Titanium Nitride (TiN) Coated - USA Made
Norseman's Ultra Bit Multi Diameter Step Drill Set is built for a superior drilling performance. Step Drills like these are used for applications that require multiple hole sizes on the same material, but without the need for multiple separate drill bits and having to change the bit after each hole is created. Step drills allow you to quickly and easily drill many holes to the same or different sizes all without having to change the bit, saving you time and money.
The round shank has flats ground onto three sides to reduce slippages of the bits when used in the drill chucks. When run in a counterclockwise direction (right hand), spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Designed for use with all thin metals, rigid plastics, wood, or composite materials with a thickness equal to or less than the step thickness. The material you use step drills with should always be no thicker than the width of each step, for the cleanest hole drilling. Also features a special axial and radial flute design to speed up workpiece penetration and a 135° split point for self centering and easy starts with no pilot hole required. Made in the USA.
