19/32" S&D Black Oxide Drill Bit

The Milwaukee 48-89-2741 is a 19/32" Silver & Deming (S&D) black oxide drill bit, built for heavy-duty, large-diameter drilling in metal, wood, and plastic.

This is a step up from the standard “jobber bit” sizes you were seeing in the 48-89-27xx range—it’s designed for bigger holes and higher load drilling while still fitting standard drills.

Key Features

• Black oxide coating – reduces friction and improves corrosion resistance
• 135° split point tip – starts on contact and helps prevent walking for accurate drilling
• Parabolic flute design – clears chips quickly to reduce heat buildup
• Reduced 1/2" shank (S&D style) – fits standard drill chucks despite large bit diameter
• Thick web construction – improves strength for heavy-duty drilling

Specs

• Size: 19/32 in (0.5938")
• Shank: 1/2" reduced shank (fits standard drills)
• Material: High-speed steel (HSS)
• Finish: Black oxide
• Type: Silver & Deming (large-diameter drill bit)
• Use: Metal, wood, PVC, plastics

Best Uses

• Large bolt and anchor holes (heavy structural hardware)
• Steel fabrication and construction work
• Thick wood beams and framing
• HVAC, plumbing, and mechanical installations
• Any application needing large diameter holes in tough materials

Bottom Line

The 48-89-2741 is no longer in the “standard twist bit” category—it’s a heavy-duty S&D drill bit designed for big holes, where strength, chip clearing, and reduced shank compatibility matter more than precision small-hole work.
