3/4" Titanium Silver & Deming Drill Bit (Milwaukee 48-89-4640)

Milwaukee 48-89-4640 3/4" Titanium Silver and Deming Drill Bit

The 3/4" Titanium Silver and Deming drill bit is Milwaukee’s large-diameter twist drill bit designed for drilling big holes in metal, wood, aluminum, and plastic, typically on a drill press or powerful handheld drill.

This specific bit is part of the Silver & Deming (S&D) category, which is used when the drill bit is too large for a standard 3/8" or 1/2" chuck to fully support.

Key idea (what “Silver & Deming” means)

A Silver & Deming bit is basically:

• A large drill bit (typically 9/16"–1")
• With a reduced 1/2" shank
• So it fits in standard 1/2" chucks

That’s why this 3/4" bit has a 1/2" shank instead of a full 3/4" shank.

Key Features

• 135° split point tip – starts cleanly and reduces walking
• Titanium nitride coating (TiN) – improves wear resistance and reduces friction
• 1/2" reduced shank (Secure Grip design) – prevents slipping in the chuck
• Jobsite-grade geometry – built for repeated drilling in tough materials
• Designed for larger hole drilling where standard bits top out
