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.
What’s included (typical set)
Usually includes core sizes such as:
- 1/8"
- 5/32"
- 3/16"
- 7/32"
- 1/4"
- 5/16"
- 3/8"
(Exact arrangement can vary slightly by production run)
Key Features
- SHOCKWAVE™ Impact Duty design – built for use with impact drivers and high-torque drilling
- 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
How it fits your list
Compared to what you’ve been going through:
- 4631 (23 pc): full range set
- 4636 (16 pc): mid-range balanced set
- 4633 (10 pc): core set
- 4637 (7 pc): small “grab-and-go” essential set
So this is basically the minimal SHOCKWAVE kit—just the most-used sizes.
Best Uses
- Everyday construction drilling
- Electrical and HVAC installs
- Metal studs, wood framing, plastics
- Impact driver quick work
- Keeping a compact jobsite kit or backup set
Bottom Line
The 48-89-4637 is the compact SHOCKWAVE essentials kit:
- Fewer bits, but all high-use sizes
- Built for speed, durability, and impact use
- Great as a portable or backup set instead of a full case
