XNF Sub-Micron Solid Carbide Twist Drill Bits – Metric

Solid Carbide Sub-Micron Jobber Twist Drill Bits – Made in USA XNF Sub-Micron Solid Carbide Twist Drill Bits – Metric Metric Solid Carbide Drill Bits – Sizes 1.0mm through 12.5mm Precision Ground • 4-Facet 118° Split Point • Made in USA The XNF Metric Solid Carbide Twist Drill Bits are precision ground from premium sub-micron solid carbide for exceptional rigidity, wear resistance, dimensional accuracy, and tool life. Designed for professional machining and production drilling, these metric carbide drill bits feature a 4-facet 118° split point for fast, accurate starts with reduced walking. A 2-flute, 25° helix provides efficient chip evacuation and smooth cutting performance in rigid machine setups. With tight diameter control and precision-ground cutting geometry, these solid carbide drills are capable of producing reamer-type hole finishes in the proper application, making them an excellent choice where hole size, finish, accuracy, and repeatability matter.
