Craftsman 32-Blade Feeler Gauge

The Craftsman 32-Blade Feeler Gauge, model CMMT14105, has become a staple in my toolbox for precise measurement tasks. This tool is designed to measure clearances between two parts, a function I find indispensable whether I'm working on automotive engines or fine-tuning 3D printer nozzles.

Build Quality and Design

One of the first things I noticed about this feeler gauge is its robust build quality. The blades are made of durable stainless steel, which is excellent for resisting corrosion. This is particularly important for me as I often work in environments where moisture and grime can easily compromise lesser tools. The full polish chrome finish adds an extra layer of protection and gives the tool a sleek, professional look. Each blade is clearly marked with its thickness, making it easy to select the right one for the job at hand.

Range and Precision

The tool features 32 blades that range from 0.0015" to 0.035" (0.038mm - 0.889mm). This range is more than sufficient for most tasks I encounter. Whether I'm checking valve clearances in an engine or measuring gaps in mechanical assemblies, the Craftsman feeler gauge provides the precision I need. The blades are accurate, and I appreciate the consistency across the set. I’ve verified several blades with a micrometer, and they match their stated measurements perfectly.

Ease of Use

Using the feeler gauge is straightforward. The blades are easy to fan out, and they stay in place once selected. This is crucial when you're working in tight spaces and need both hands free. The tool's compact size (6.9 inches in length and 0.9 inches in height) makes it easy to carry around, yet it's substantial enough to feel sturdy in hand. One minor gripe is that the tool can be a bit oily out of the package, but this is a small price to pay for rust prevention.

Practical Applications

In my experience, this feeler gauge has proven invaluable for a variety of applications. For automotive work, it’s perfect for checking spark plug gaps, valve clearances, and other critical measurements. In the realm of 3D printing, it’s ideal for ensuring nozzle gaps are just right, which is essential for high-quality prints. The range of sizes available means I can always find the perfect blade for the job, no matter how precise the measurement needs to be.

Issues and Concerns

Despite its many strengths, there are a couple of areas where the Craftsman feeler gauge could improve. Some users might find the packaging and labeling confusing. The packaging indicates a range of 0.015" to 0.035", but the actual range starts at 0.0015". This discrepancy can lead to misunderstandings and potential returns. Additionally, there have been instances where the thumb screw that holds the blades together has come loose, which is frustrating but not a deal-breaker. A quick tightening usually resolves the issue.

Durability and Maintenance

The stainless-steel construction ensures that the blades remain rust-free, provided they are kept oiled. Over time, I’ve found that a light coat of oil is sufficient to keep the blades in good condition. The tool’s durability is evident in its performance; even after extensive use, the blades remain straight and true. The full lifetime warranty offered by Craftsman provides additional peace of mind, knowing that the company stands behind its product.

Value for Money

At its price point, the Craftsman feeler gauge offers excellent value. It combines high-quality materials, precise measurements, and a wide range of applications into a single, affordable package. Comparatively, it outperforms many other feeler gauges that cost significantly more, making it a smart investment for both professionals and DIY enthusiasts.

Final Thoughts

The Craftsman 32-Blade Feeler Gauge is a reliable, well-made tool that delivers on its promises. Its durability, precision, and ease of use make it an essential addition to any toolbox. While there are minor issues with packaging and the thumb screw, these are easily overlooked given the tool’s overall performance and value.

I highly recommend this feeler gauge for anyone in need of precise measurement tools. Whether you're a seasoned mechanic, a hobbyist, or someone who simply enjoys working on detailed projects, this tool will meet your needs and exceed your expectations.
