SHOCKWAVE™ 2" Impact Slotted 3/16" & 1/4" Power Bit (2 PK)

What it is:

The 48-32-4920 is a Milwaukee SHOCKWAVE™ Impact Duty 2" Slotted (flathead) driver bit set – 2 pack, used with impact drivers and drill drivers.

Key specs:

• Type: Slotted (flathead)
• Sizes included: 3/16" (#8) and 1/4" (#10)
• Length: 2 inches
• Quantity: 2 bits per pack
• Shank: 1/4" hex quick-change
• Material: Alloy76™ steel

Key features:

• SHOCKWAVE™ design: Built for high-torque impact use
• Shockzone™ geometry: Absorbs peak torque and reduces breakage
• Wear Guard™ tip: Extends bit life and maintains fit over time
• Precision-machined tip: Reduces stripping and wobble
• Laser-hardened tip: Improves durability at contact point
• Designed for impact drivers & drills

In plain terms:

This is a flathead screwdriver bit set, which is now mostly used in:

• electrical work (older devices, panels, terminals)
• light maintenance and utility work
• occasional specialty fasteners

Slotted bits are less common today because they:

• slip more easily than Phillips/Torx/square
• require more careful alignment

Milwaukee reinforces them so they can actually survive impact-driver use.
