Milwaukee 48-89-4637 — Product Description

The Milwaukee 48-89-4637 is a 7-piece SHOCKWAVE™ Impact Duty RED HELIX™ titanium drill bit set, designed for fast, durable drilling in metal, wood, and plastic, especially when used with impact drivers or drill drivers.

This is one of the smaller SHOCKWAVE drill bit kits, focused on the most commonly used sizes for jobsite work.

  (Exact arrangement can vary slightly by production run)

Key Features

• RED HELIX™ flute geometry – variable helix improves chip removal and reduces heat buildup
• QUAD EDGE™ tip – four cutting edges for faster starts and cleaner holes
• 135° split point tip – prevents walking on metal surfaces
• Titanium coating (TiN) – extends life significantly compared to standard black oxide bits
• 1/4" hex shank – quick-change compatible for jobsite efficiency
