Precision Twist Drill 5997097 1/8 in Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5997097 is a 1/8 inch high speed steel (HSS) jobber-length drill bit engineered for general-purpose drilling in a wide range of materials. It features a 135-degree split point geometry with web thinning, which reduces walking on entry and lowers the thrust needed to start a hole. The bright, uncoated finish is standard for HSS tooling used in lower-heat applications. With an overall length of 2.75 inches and a 1.625 inch flute length, this bit fits standard drill chucks and is appropriate for bench drill presses, hand drills, and drill motors used in trade and light industrial settings.

This drill bit is suited for drilling into steel, aluminum, and non-ferrous metals, making it a practical choice for HVAC, electrical, plumbing, and general fabrication work. The straight cylindrical shank with a 0.125 inch diameter seats securely in standard three-jaw chucks. The regular spiral flute design promotes chip evacuation during through-hole and blind-hole drilling. It is sold as a single unit and is sized within the 0.1000 to 0.1500 inch decimal inch range class.

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with any standard three-jaw chuck rated for 1/8 inch straight shank tooling, including bench drill presses, hand drills, and drill motors used in HVAC, electrical, plumbing, and light fabrication applications.

Installation Notes

Install and remove drill bits only after the drill motor is fully powered down and the chuck key is clear of the chuck. Secure the shank fully into the chuck jaws and tighten evenly before operation. Use appropriate cutting fluid or coolant when drilling harder steels to extend bit life, as this bit does not support through-tool coolant delivery. Dispose of worn or chipped bits according to applicable shop safety protocols.
