The Milwaukee 48-89-4633 is a 10-piece SHOCKWAVE™ Impact Duty RED HELIX™ titanium drill bit set, designed for high-performance drilling in metal, wood, and plastic, especially when using impact drivers or drill drivers.

This is the full set version of the 4600-series SHOCKWAVE bits you’ve been going through, bundling the most commonly used sizes into one organized case.

• 1/8"
• 9/64"
• 5/32"
• 11/64"
• 3/16"
• 7/32"
• 1/4"

• 3/8"
  (plus a duplicate 1/8" in many kits depending on revision)

Key Features

• SHOCKWAVE™ Impact Duty design – built for impact drivers and high torque use
• RED HELIX™ flute geometry – variable helix improves chip removal and reduces heat
• QUAD EDGE™ tip – four cutting edges for faster starts and cleaner holes
• 135° split point tip – prevents walking on metal
• Titanium coating (TiN) – longer life vs standard black oxide bits (up to ~5×)
• 1/4" hex shank – quick-change compatible for jobsite use

What makes this one different

Compared to the individual 48-89-4600 series bits you were listing:

• Those are single bits
• This is a ready-to-go set
• Designed for fast access + organization (often PACKOUT-compatible case)

• Electrical, HVAC, and general construction installs
• Metal studs, sheet metal, wood framing, plastics
• Impact driver + drill combo work
• Reducing downtime from swapping bit sizes

Bottom Line

The 48-89-4633 is basically Milwaukee’s “grab-and-go SHOCKWAVE drill bit kit”:

• Covers all the common sizes in one case
• Built for impact drivers + durability + speed
• More efficient than buying individual 46xx bits
• Designed for real jobsite use, not just shop storage
