Milwaukee 48-89-2742 — Product Description
Milwaukee 48-89-2742 5/8" S&D Black Oxide Drill Bit
The Milwaukee 48-89-2742 is a 5/8" Silver & Deming (S&D) black oxide drill bit, designed for heavy-duty, large-diameter drilling in metal, wood, and plastic.
This is a reduced-shank bit, meaning it has a 1/2" shank so it can still be used in a standard 1/2" drill chuck even though the cutting diameter is much larger.
Key Features
-
135° split point tip – starts on contact and reduces walking for accurate holes

-
Parabolic flute design – clears chips quickly to reduce heat buildup
-
1/2" reduced shank (3-flat) – prevents slipping in the chuck and fits standard drills
