XNF Sub-Micron Solid Carbide Twist Drill Bits – Fractional

XNF Sub-Micron Solid Carbide Twist Drill Bits – Fractional

Fractional Solid Carbide Drill Bits – Sizes 1/64″ through 1/2″
Precision Ground • 4-Facet 118° Split Point • Made in USA

The XNF Fractional 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 fractional 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.

Solid carbide provides substantially greater rigidity and wear resistance than conventional HSS or cobalt drills. In rigid machining setups, XNF carbide drills provide excellent hole quality, cutting-edge stability, dimensional control, and extended tool life, especially in abrasive materials and production applications.

For best tool life, hole quality, and cutting performance, use the proper speeds and feeds with coolant or cutting fluid directed at the point of cut.
