Precision Twist Drill 5999199 Jobber Drill Bit No. 50

Product Description

The PRECISION TWIST DRILL 5999199 is a jobber-length twist drill bit sized to wire gauge No. 50, equal to 0.0700 inches in decimal. It is manufactured from high speed steel with a steam oxide coating that reduces friction and helps resist corrosion during cutting operations. The bit features a standard 118-degree point angle, a regular spiral flute, and a straight-cylindrical shank. Overall length is 2 inches with a 1-inch flute length and a maximum drilling depth of 1 inch. This is a general-purpose drill intended for use by machinists, maintenance technicians, and fabricators working with ferrous and non-ferrous materials.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in production and maintenance environments. The tapered web with web-thinned geometry reduces the thrust required at entry and improves chip evacuation in deep holes relative to flute length. It conforms to ANSI standards and falls within the R10-R15-R18 series. Typical applications include through-hole drilling, pilot hole creation, and precision hole sizing in light to medium-duty drilling setups on drill presses or hand-held power tools.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in a properly rated drill chuck before operation and verify chuck key is removed before powering the spindle. Do not exceed the recommended speed range for the workpiece material and bit diameter. Always wear appropriate eye protection and secure the workpiece firmly to prevent movement during drilling.
