Precision Twist Drill 5995914 No 49 Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5995914 is a No. 49 wire-gauge jobber-length drill bit designed for precision drilling in demanding materials. Built from high-speed steel (HSS) with a straw bronze coating, it features a 135-degree split point and a web-thinned, tapered web configuration that reduces walking and lowers thrust on entry. The straight shank measures 0.0730 inches in diameter, and the bit runs 2.0 inches overall with a 1.0-inch flute length. Two regular spiral flutes clear chips efficiently during through-hole and blind-hole operations. This bit is graded heavy duty and conforms to ANSI standards, making it a reliable choice for machinists, maintenance technicians, and trade professionals working in tight tolerances.

The 5995914 is rated for drilling high-temperature alloys and is broadly suited for general-purpose metal drilling across workpiece material categories P, M, K, and S. Its compact 2.0-inch overall length makes it well-suited for benchtop drill presses, handheld power drills, and CNC drilling applications where a small wire-gauge bit is required. The 1.0-inch maximum drilling depth keeps cuts within the supported flute length to maintain hole quality and bit life.

Key Features

Compatibility

Designed for use in Series HX10, HX15, and HX18 applications. Fits standard drill chucks accepting a 0.0730-inch straight shank.

Installation Notes

Installation and use of this drill bit should follow standard machining safety practices. Secure the workpiece fully before drilling and confirm the chuck is tightened properly before applying power. Use appropriate cutting fluid or coolant for the workpiece material to maintain bit temperature and extend service life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
