29PC SHOCKWAVE™ Impact Duty RED HELIX™ Titanium Drill Bit Set

The Milwaukee 48-89-4672 is a 29-piece SHOCKWAVE™ Impact Duty RED HELIX™ titanium drill bit set, built for high-performance drilling in metal, wood, and plastic, including use with impact drivers.

Key Features

• SHOCKWAVE Impact Duty™ Design – Engineered for use with both impact drivers and drill drivers
• RED HELIX™ Technology – Combines multiple features for speed and durability:
  • QUAD EDGE™ Tip – 4 cutting edges for fast starts and reduced walking
  • Variable Helix Flute (35° → 15°) – Rapid chip removal to reduce heat
  • Thicker Tapered Web – Increased strength and resistance to breakage
• Titanium Coating (TiN) – Up to 5× longer life vs. black oxide bits
• 1/4" Hex Shank – Quick-change compatible with impact drivers
• Laser-Etched Sizes – Easy identification even after wear
• PACKOUT™-Compatible Case – Durable, modular storage system

Set Details

• 29 pieces covering a wide range (approx. 1/16" to 1/2")
• Jobber-length bits for general-purpose drilling

Best Uses

• Drilling steel and other metals
• Wood and plastic applications
• General construction, electrical, HVAC, and maintenance work
• Ideal when using impact drivers regularly (stronger than standard bits)

Why This Set Stands Out

Compared to standard titanium sets (like the 48-89-0011 you asked about earlier), this one:

• Is impact-rated (big upgrade if you use an impact driver)
• Has more aggressive chip removal for faster drilling
• Offers higher durability under heavy load
