Klein Tools 32787 Precision Ratchet & Driver System Kit (64pc) - A Pro's Take

As someone who lives and breathes DIY and professional tool use, I'm always on the lookout for quality, versatility, and value. Klein Tools’ 32787 64-piece Precision Ratchet & Driver System Kit definitely caught my eye, and after putting it through its paces, here’s my detailed assessment.

Overview & First Impressions:

This kit aims to be a comprehensive solution for small fastener work – electronics repair, watchmaking, jewelry making, model building, and general precision tasks. The presentation is typical Klein – robust plastic case with clearly labeled slots for each component. The case itself feels durable and designed to withstand workshop life. Initial heft suggests good material quality, but the real test is in the performance.

Key Features & Specifications:

Drive Size: 1/4" – This is the core of the system. It’s small enough for intricate work, yet provides enough leverage for reasonable torque.
Ratchet: The included ratchet is a standout. It’s a slim-profile, 80-tooth ratchet, offering a low 4.5° swing arc. This is crucial in tight spaces. The ratcheting action is smooth and positive, with no noticeable backplay. The quick-release button works flawlessly.
Bits: The kit boasts 60 precision bits, covering a wide range of screw types: Phillips, Slotted, Torx, Hex, Pozidriv, and Nut Driver. The bits are made from Chrome Vanadium Steel (Cr-V), which is a good baseline for durability. Bit markings are clear and easy to read, even in low light.
Adapters & Accessories: Includes a bit holder, a 1/4" to 1/4" adapter, and a 1/4" to 6.35mm (1/4") adapter. These add versatility for using existing 1/4" drive accessories.
Case: As mentioned, the molded plastic case is well-organized and keeps everything secure. It's not the smallest kit, but the organization is worth the footprint.
Weight: Approximately 2.2 lbs (fully kitted) – manageable for portability.

Performance & Usage:

I tested this kit on a variety of tasks, from disassembling electronics to tightening small screws in furniture. The low swing arc of the ratchet is a game-changer. It allowed me to work in areas where a standard ratchet simply wouldn’t fit. The bit engagement is solid, with minimal cam-out, even under moderate pressure.

The Cr-V bits held up well to repeated use, showing no signs of rounding or chipping. I did notice that some of the Torx bits felt slightly softer than the Phillips or Slotted, so applying excessive force with those is not recommended.

The bit holder is a nice addition, allowing for extended reach and better control. The adapters are useful for integrating this kit with other tools.

Pros:

Excellent Ratchet: The 80-tooth, low-swing arc ratchet is the star of the show.
Comprehensive Bit Selection: Covers a wide range of screw types and sizes.
Durable Construction: Cr-V steel bits and a robust case.
Well-Organized: The case keeps everything neat and accessible.
Good Value: Considering the quality and quantity of components, the price is competitive.

Cons:

Torx Bit Hardness: Torx bits feel slightly softer than other bit types.
Case Size: While organized, the case is relatively large.
Not for Heavy-Duty Applications: This is a precision kit, not a general-purpose one. Don't expect it to handle high-torque applications.

Overall:

The Klein Tools 32787 Precision Ratchet & Driver System Kit is a fantastic addition to any DIYer’s or professional’s toolkit. It excels in situations where space is limited and precision is paramount. While the Torx bits could be a bit harder, the overall quality, versatility, and value make this kit a winner. I highly recommend it for anyone working with small fasteners in electronics, jewelry, model building, or similar applications. It's a solid investment that will save you time and frustration.
