Milwaukee 48-89-2718 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2718 is a black oxide jobber length drill bit built for demanding jobsite conditions. It measures 6 inches in length and features a 135-degree split point tip that starts on contact, eliminating walking and delivering fast, accurate holes without a center punch. The thicker-than-standard web core resists side-load breakage and extends service life. A parabolic flute geometry clears chips and debris rapidly, reducing heat buildup during drilling. The black oxide coating adds lubricity and corrosion resistance. Licensed trades and general contractors reach for this bit when drilling on curved or irregular surfaces with portable drills.

This drill bit is suited for metal drilling applications in residential, commercial, and industrial settings. The reduced shank diameter allows use in 3/8-inch chucks, making it compatible with a wide range of portable drills. The 3-flat Secure-Grip shank prevents slipping in the chuck during high-torque applications, which matters when drilling through structural steel, angle iron, or sheet metal on the job. It is sold individually and is a staple for electricians, HVAC technicians, pipefitters, and general construction trades who need a reliable, general-purpose twist bit on hand.

Installation Notes

A licensed tradesperson or qualified technician should select the correct bit diameter and confirm the drill chuck is properly tightened before operation. Wear appropriate eye protection and secure the workpiece before drilling. Allow the bit to cool between extended drilling cycles to preserve edge life. Do not use in hammer-drill mode, as impact force will damage the cutting edges.
