Precision Twist Drill 5995484 3/16 Inch Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5995484 is a jobber-length drill bit designed for general-purpose drilling in steel, cast iron, and similar ferrous and non-ferrous materials. It measures 3/16 inch (0.1875 inch) in diameter with a 118-degree standard point angle and a bright, uncoated HSS construction. The left-hand cutting direction makes this bit particularly useful when removing broken fasteners or studs, since the bit's rotation tends to back the damaged fastener out as it drills. Licensed tradespeople and maintenance professionals working with metalworking or mechanical repair tasks are the primary users of this bit.

This bit fits standard drilling operations in residential and commercial maintenance, light fabrication, and repair environments. The Series L10 designation places it in a general-purpose jobber-length family intended for straight-shank drill chucks. Primary workpiece materials include steel and cast iron, though the HSS construction also supports aluminum, non-ferrous metals, and similar materials. The 2-flute regular spiral flute configuration promotes chip evacuation during through-hole drilling.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and trade professionals using hand drills or drill presses equipped with a keyed or keyless chuck. Secure the straight shank firmly in the chuck before operation and ensure the workpiece is clamped or fixtured to prevent movement. When using a left-hand bit for fastener extraction, apply consistent downward pressure and moderate speed to encourage the fastener to back out before the bit penetrates deeply. Wear appropriate eye protection per standard shop safety practices.
