Precision Twist Drill 5995894 No. 44 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5995894 is a No. 44 wire-gauge jobber-length drill bit designed for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium. Manufactured from high speed steel with a bronze coating, it features a 135-degree split point and a web-thinned, tapered web construction that reduces walking and lowers entry force on hard materials. The straight cylindrical shank measures 0.086 inches in diameter, and the bit carries a total overall length of 2.125 inches with a spiral flute length of 1.125 inches. This bit is suited for machine shop, maintenance, and fabrication applications where precision hole sizing in tough workpiece materials is required.

The 5995894 fits standard drill chucks and is commonly used in drill presses, CNC drilling operations, hand-held power drills, and turret lathes. Its 0.086-inch decimal diameter corresponds to the No. 44 wire gauge size, making it the correct choice when tapping or clearance holes must be held to that precise diameter. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. The bit conforms to ANSI standards and falls within the HX10-HX15-HX18 series.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson following applicable shop safety procedures.
