Specifications:

• Drive Size: 1/4-inch
• Socket Sizes: 5/16-inch & 3/8-inch
• Socket Type: 6-Point Impact & Magnetic Hex
• Material: Chrome Vanadium Steel (likely, Klein doesn’t explicitly state this, but it’s standard for their impact line)
• Finish: Black Oxide (provides corrosion resistance and reduces glare)
• Weight (Set): Relatively lightweight, around 4.5oz for both sockets.
• Impact Rated: Yes, designed for use with impact drivers.

Performance & Features:

The core strength of this set is its convenience. The flip design does save time. I frequently encounter situations – particularly in automotive work and equipment repair – where I need both 6-point and hex sockets of the same size. Being able to switch between them instantly without rummaging through a socket set is a genuine benefit.

The 6-point impact sockets themselves are well-machined. The engagement is solid, and I experienced no rounding of fasteners even when applying significant torque with a mid-range impact driver. The black oxide finish feels durable and provides a good grip.

The magnetic hex sockets are a clever addition. The magnet isn't overpowering – which is good. It holds standard hex bits securely, but doesn’t make removal overly difficult. I tested it with various bit lengths and materials, and it performed consistently. The hex socket side is also surprisingly robust; I didn't notice any flex or deformation under load.

Pros:

• Time-Saving: The flip design significantly reduces tool changes.
• Versatility: Combines two essential socket types in one tool.
• Impact Rated: Built to withstand the stresses of impact drivers.
• Durable Construction: Appears well-made with quality materials.
• Magnetic Hex Socket: Securely holds hex bits.
• Compact Size: Easy to store and carry.

Cons:

• Limited Size Range: Only two sizes are included. Expanding the set with more common sizes (7/16", 1/2") would greatly increase its usefulness.
• Potential for Wear: The flip mechanism, while solid, introduces a potential wear point over extended use. Time will tell how well it holds up.
• Price: At around $25-30 for two sockets, it's more expensive than buying standard individual impact sockets. You're paying for the convenience.

Overall:

The Klein Tools 32768 3-in-1 Impact Flip Socket Set is a well-executed idea that delivers on its promise of convenience. While the limited size range and price point might deter some, the time saved and versatility offered make it a worthwhile addition to any DIYer or professional’s toolkit, especially if you frequently work with both 6-point and hex fasteners of these sizes. I’d like to see Klein expand this line with more sizes and potentially different drive sizes (3/8" and 1/2"). It’s a solid 4 out of 5 stars.
