11/16" S&D Black Oxide Drill Bit

The Milwaukee 48-89-2744 is a 11/16" Silver & Deming (S&D) black oxide drill bit, designed for heavy-duty, large-diameter drilling in metal, wood, and plastic.

It belongs to Milwaukee’s S&D (reduced shank) series, meaning it has a 1/2" shank so it can be used in standard drill chucks despite its large cutting diameter.

Key Features

• 135° split point tip – starts on contact and prevents walking for accurate drilling
• Black oxide coating – reduces friction and improves corrosion resistance
• Parabolic flute design – clears chips quickly for cooler, faster drilling
• 1/2" reduced shank with 3 flats – prevents slipping in the chuck and fits standard drills
• Heavy-duty web construction – increases strength for large-hole drilling

Specs

• Size: 11/16 in
• Shank: 1/2" reduced (S&D style)
• Material: High-speed steel (HSS)
• Finish: Black oxide
• Overall length: ~6 in
• Use: Metal, wood, PVC, plastics

Best Uses

• Large structural bolt holes
• Steel fabrication and construction work
• Thick wood beams and framing
• HVAC, plumbing, and mechanical installs
• Any application requiring large diameter drilling with a standard drill

Bottom Line

The 48-89-2744 is a heavy-duty S&D drill bit, not a standard twist bit. It’s designed for big structural holes where strength, chip evacuation, and compatibility with a normal 1/2" drill matter most.
