Milwaukee 48-89-2723 Black Oxide Jobber Drill Bit 6 in

Product Description

The MILWAUKEE 48-89-2723 is a black oxide jobber length drill bit engineered for extreme durability in demanding jobsite conditions. The Thunderbolt web uses a thicker core than a standard drill bit, providing greater resistance to side-load breakage. A parabolic flute geometry clears chips and debris quickly to reduce heat buildup during drilling. The 135-degree split point tip starts on contact without walking, delivering fast, accurate hole starts. At 6 inches in length, this bit suits a wide range of general-purpose drilling tasks and is well suited for use with portable drills. Installation or use requires no special licensing, but appropriate PPE is always recommended.

This drill bit is designed for drilling in metal, wood, and general construction materials encountered on commercial and residential jobsites. The reduced shank diameter allows compatibility with 3/8-inch chucks, expanding its usefulness across a variety of portable and bench-mounted drills. The 3-flat shank geometry reduces slipping in the chuck during high-torque applications. It is a practical choice for electricians, plumbers, HVAC technicians, and general contractors who need reliable, consistent hole placement on curved or flat surfaces.

Key Features

• Thicker Thunderbolt web core resists side-load breakage and extends bit life
• 135-degree split point tip starts on contact and prevents walking on curved or flat surfaces
• Parabolic flute design clears chips and debris rapidly to keep the bit running cool
• 3-flat shank securely seats in the drill chuck to reduce slipping under load
• Reduced shank diameter fits standard 3/8-inch chucks for use with common portable drills
• Black oxide coating provides lubricity and corrosion resistance throughout the bit life

Compatibility

Designed for use with standard portable and bench drills equipped with 3/8-inch or larger keyed or keyless chucks. Suitable for general-purpose jobber-length drilling applications across trade disciplines.

Installation Notes

Secure the 3-flat shank firmly in the drill chuck before operation. Power down and unplug or lock out the drill before changing bits. Wear appropriate eye protection when drilling, as chip ejection is accelerated by the parabolic flute design. Inspect the bit for wear or damage before each use and replace if the cutting edges show signs of dulling or chipping.
