3/32" Thunderbolt® Black Oxide Drill Bit (12 PK)

The Milwaukee 48-89-2822 is a 3/32" Thunderbolt® black oxide drill bit set (12-pack) used for general-purpose drilling in metal, wood, and plastic.

It’s a standard jobber-length Thunderbolt bit, meaning it’s designed for everyday use and durability, especially for small precision or pilot holes.

Key Features

• 135° split point tip – starts on contact and helps prevent walking for accurate holes
• Black oxide coating – reduces friction and improves corrosion resistance
• Thicker “Thunderbolt” web design – increases strength and reduces breakage
• Parabolic flute design – clears chips quickly for cooler, faster drilling
• 3-flat Secure-Grip shank – helps prevent slipping in the drill chuck

Specs

• Size: 3/32 in
• Quantity: 12 bits per pack
• Material: High-speed steel (HSS)
• Finish: Black oxide
• Length: ~2-1/4 in jobber length
• Use: Metal, wood, PVC, plastics

Best Uses

• Pilot holes for screws and anchors
• Light metal drilling
• Woodworking and trim work
• General maintenance and shop use
• Small, precise drilling tasks where control matters

Bottom Line

The 48-89-2822 is a basic small-diameter Thunderbolt drill bit set—built for everyday precision and pilot holes, not heavy structural drilling or specialty reach applications like the S&D or aircraft-length bits you were looking at earlier.
