Bosch 7-1/4 Inch 4 Tooth Fiber Cement Circular Saw Blade

Cutting fiber cement can be quite a challenge. It's a tough material that requires a blade that can handle the job without wearing out too quickly. Enter the Bosch 7-1/4 Inch 4 Tooth Fiber Cement Circular Saw Blade (CB704FC). Having had the chance to put this blade through its paces, I can confidently share my thoughts and experiences with you.

First off, let’s talk about the build quality. The blade is constructed with polycrystalline diamond tips, which are known for their exceptional durability. These tips are designed to extend the blade's life significantly compared to standard carbide-tipped blades. In my experience, this feature is not just a marketing gimmick; it genuinely makes a difference. After making numerous cuts through tough fiber cement boards, the blade still looked and performed like new.

The thin kerf design of the blade is another standout feature. It allows for fast and accurate cuts, which is particularly important when working with fiber cement. A thicker blade would create more resistance and potentially more dust, but the thin kerf of this Bosch blade slices through material efficiently. I noticed that it required less effort to push the saw through the material, which is always a plus when you’re working on a large project.

Speaking of dust, the anti-friction coating on this blade does a commendable job of reducing it. Fiber cement is notorious for generating a lot of dust, which can be a health hazard and a nuisance. While no blade can completely eliminate dust, the Bosch CB704FC certainly minimizes it more effectively than other blades I've used. The anti-friction coating helps the blade glide through the material smoothly, which in turn reduces the amount of dust kicked up. This feature is particularly beneficial if you’re working in an enclosed space or a residential area where dust control is a concern.

Compatibility is another area where this blade shines. It fits both standard and worm drive saws, making it a versatile addition to any tool collection. I used it with my standard circular saw, and it fit perfectly without any issues. The blade's 5/8-inch arbor is pretty standard, so it should fit most saws without any modifications. The 7,900 RPM max speed rating is also more than adequate for most cutting tasks, ensuring that the blade operates smoothly even at high speeds.

One of the most impressive aspects of this blade is its cut quality. The 4-tooth configuration might seem sparse compared to blades with more teeth, but don’t let that fool you. Each tooth is designed to make clean, precise cuts, and in my experience, it does just that. The cuts were smooth and required minimal sanding or touch-up work. This is crucial when working with fiber cement, as rough or jagged cuts can compromise the integrity of the material.

Now, let’s talk about longevity. After making around a hundred cuts through 8-inch Hardie plank, the blade still performed exceptionally well. There was no noticeable decline in cutting efficiency or quality. This durability is a testament to the polycrystalline diamond tips and overall construction quality of the blade. If you’re tired of replacing blades frequently, this Bosch blade is definitely worth considering.

However, no tool is without its drawbacks. While the Bosch CB704FC excels in many areas, it’s not the cheapest option on the market. If you’re on a tight budget, you might find the initial cost a bit steep. That said, the blade's longevity and performance can actually save you money in the long run by reducing the need for frequent replacements.

Another minor downside is that the blade can struggle a bit with extremely dense or thick fiber cement boards. While it handles standard boards with ease, I noticed a slight decrease in efficiency when cutting through particularly dense material. It’s not a deal-breaker by any means, but it’s something to keep in mind if you often work with thicker boards.

In summary, the Bosch 7-1/4 Inch 4 Tooth Fiber Cement Circular Saw Blade (CB704FC) is a high-quality, durable blade that excels in cutting fiber cement. Its polycrystalline diamond tips, thin kerf design, and anti-friction coating make it a standout choice for anyone who frequently works with this challenging material. The blade's compatibility with both standard and worm drive saws adds to its versatility, and its impressive longevity makes it a cost-effective option in the long run.

Would I recommend this blade? Absolutely. While it may have a higher upfront cost, its performance, durability, and overall quality make it a worthwhile investment. If you need a reliable blade that can handle the rigors of cutting fiber cement, the Bosch CB704FC is definitely up to the task.
