DeWalt Straight Cut Aviation Snips Review

4.8 out of 5

Straight cut aviation snips are a staple in any toolbox, and the DeWalt DWHT70279 model certainly stands out. Having spent some time with these snips, I can confidently say they live up to DeWalt's reputation for delivering high-quality, durable tools.

Design and Build Quality

The first thing that struck me about these snips is their robust construction. The blades are made from forged chrome molybdenum alloy, which DeWalt claims is 30% to 50% stronger than the cast steel used in some other brands. This material choice not only contributes to the tool's durability but also ensures a longer cutting life. The overall length of the snips is 6.5 inches, making them compact yet substantial in hand.

One of the standout features is the patented flush hardware. This design element allows for smooth access from a pouch, a small but significant detail that enhances the tool's ease of use. Additionally, the 25% larger pivot bolt compared to competitors adds to the tool's longevity, providing a more stable and durable pivot point.

Comfort and Usability

Comfort is crucial when it comes to hand tools, and DeWalt has clearly kept this in mind. The snips sit well in hand, with a handle design that is both ergonomic and comfortable. The yellow and black handle is not just aesthetically pleasing but also functional, providing a good grip even when wearing gloves or working in less-than-ideal conditions.

The internal locking mechanism with auto-release is another thoughtful feature. This mechanism ensures the snips are securely locked when not in use, but they release automatically when needed, adding a layer of safety and convenience. The design makes it easy to use the tool with one hand, which can be a significant advantage when working on complex projects.

Performance

In terms of performance, the DeWalt snips excel. They are designed for straight cuts and handle 18 gauge cold-rolled steel and 23 gauge stainless steel with ease. The cutting edge length is 1.5 inches, which provides a good balance between precision and the ability to handle larger materials. During my tests, the snips cut through various materials smoothly and without much effort, a testament to the sharpness and quality of the blades.

One of the aspects I particularly appreciated was the tool's balance. It feels neither too heavy nor too light, striking a perfect middle ground that allows for controlled, precise cuts. This balance, combined with the ergonomic handle, makes the snips less fatiguing to use over extended periods.

Durability

Durability is a critical factor for any tool, and the DeWalt snips do not disappoint. The forged chrome molybdenum alloy blades are built to last, and the overall construction feels solid and reliable. The larger pivot bolt adds to this sense of durability, ensuring the tool can withstand regular use without loosening or degrading.

I also appreciated the internal locking mechanism, which feels robust and reliable. It’s a small feature, but one that speaks to the overall build quality of the tool. The snips have been designed to withstand the rigors of daily use, and it shows.

Value for Money

Given the quality and performance of these snips, they offer excellent value for money. While they may be slightly more expensive than some other models on the market, the investment is justified by the tool's durability and superior performance. The features like the flush hardware, larger pivot bolt, and internal locking mechanism add to the overall value, making this tool a worthwhile addition to any toolkit.

Final Thoughts

Overall, the DeWalt DWHT70279 aviation snips are an excellent tool for both professional and DIY use. They combine durability, comfort, and performance in a well-designed package. The forged chrome molybdenum alloy blades ensure a longer cutting life, while the ergonomic handle and balanced design make them comfortable to use over extended periods.

The additional features like the patented flush hardware and internal locking mechanism add to the tool's usability and safety, making it a reliable choice for a wide range of cutting tasks. Whether you're cutting through cold-rolled steel or stainless steel, these snips handle the job with ease and precision.

In conclusion, I would highly recommend the DeWalt DWHT70279 aviation snips. They offer a perfect blend of quality, performance, and value, making them a standout choice in their category. If you're in the market for a reliable pair of snips that will last, these are definitely worth considering.
