When it comes to the lumber you need to build virtually anything and everything, the 2×4 is always going to have its uses. These boards are used for roofing, flooring, building walls, frames, sheds, and so much more. These strong pieces of wood are very versatile in nature.
也就是說，他們並不總是削減到你需要的大小，這意味著你需要自己削減它們。當涉及切割2x4s時，使用的最佳工具之一是圓鋸。有了這個，讓我們涵蓋用圓鋸切割這種類型的電路板所需的一切。
是圓形的，看到了切割2x4s的最佳工具嗎？
如果您想知道切割2x4s的最佳工具是什麼，那麼是的，圓鋸絕對是考慮的最佳選擇。大型圓形刀片以極高的速度移動，從而快速工作幾乎您放在它麵前的任何東西。還值得注意的是，圓鋸可以配備各種刀片類型，其中一些最適合軟木，一些硬木，有些是為了工程木材也。
由於圓鋸的尺寸，形狀和快速移動，最好用於製作橫切（寬度方向）。您可以在一秒鍾或更短的時間內使用圓形鋸進行交叉切割2×4。也就是說，圓鋸也可用於使RIP切割（縱向）通過2x4s，雖然這允許比橫切更難。一個大型桌子看到這項任務可能會更好，特別是如果你需要削減大量的2x4s。
在同一個備注上，如果你手頭沒有圓鋸，使用斜切鋸is always a good option, and yes, the aforementioned table saw as well. However, let’s keep in mind that miter saws are not overly portable, and they require you to lay the wood onto the integrated worktable to cut it. Table saws also require you to place the workpiece onto the integrated table, and unless you get a benchtop model (which is not ideal for large stock), it’s not going to be very portable either.
圓形鋸小，輕巧，便攜，但足夠大而強大，以便能夠輕鬆處理2x4s，而您將在下麵進一步了解，與大多數其他鋸不同，它們可以立即處理多個2x4s。
How to Cut a 2×4 with a Circular Saw
既然你知道圓鋸一般是切割2x4s的最佳工具，無論是撕裂切割還是橫切，讓我們弄清楚如何實際做到這一點。
第1步：檢查鋸
The first thing that you should do no matter the task at hand is to inspect your circular saw to see that it is in working condition. Make sure that the lower blade guard, the wiring, and the blade are all in good condition. The blade guard is crucial for your safety, and having a sharp blade that is not damaged or warped is also crucial to being able to make a straight cut.
第2步：設置刀片深度
為了削減2x4s，您需要在適當的深度設置刀片。切割2×4時，您希望在長凳或桌子上保持更長的側麵（4英寸的側麵），因此您的刀片隻需要削減2英寸深度。
As a rule of thumb, to ensure that the blade is set deep enough to make the cut, but also so that it does not protrude out too far past the workpiece, you want to set the blade at 1/4-inch deeper than the cut being made. Therefore, for this purpose, set the circular saw blade to a bit less than 2-1/4 inches since 2x4s are usually worked down to a slightly smaller dimensions.
第3步：支持木材
看到作為圓鋸沒有自己的桌子，你需要支持木材。因此，將木頭放在鋸木或工作台上。您希望將被切斷的部分突出到突出表麵（因此您不會切入替補席，Sawhorse或表格）。在2×4的另一邊，您需要支持的側麵。
Now, many people are going to tell you that you want to clamp it down for maximum safety. Yes, this is an option, although you can always just use your free hand to hold it down as well. Just make sure to apply plenty of pressure if you are holding the 2×4 down manually.
Step 4: Measure, Mark, & Make the Cut
現在，拿你的統治者並衡量需要被切斷的金額。您可能還想使用T-Square來確保您正在切割完美的90度角。我們假設你在這裏沒有切成一角，以便T-Square將派上用場。
一旦你用鉛筆標記線路，你就可以減掉你的剪輯。
首先，啟動圓形鋸並將其達到全速，然後以一個穩定的運動通過木材。
You have now cut a 2×4 with a circular saw.
你可以用圓鋸一次剪下多個2x4s嗎？
是的，您可以使用圓鋸請立即剪切多個2x4s。然而，請記住，他們需要彼此旁邊，而不是彼此的旁邊。就像你在桌子或長凳上放一個2×4一樣，用多個2x4s這樣做。
Simply place them so they are all perfectly lined up, thus allowing you to make multiple cuts with one straight motion.
When doing this, it is hard to hold down all of the 2x4s manually, so clamping down the individual boards to the table or bench is strongly recommended. If all of your marks are perfectly lined up, you can start the saw, get it up to full speed, and pass it through all of the 2x4s with a single sweep.
Can You Use a Circular Saw to Do Miter and Bevel Cuts on 2x4s?
斜切和斜麵切割是用圓鋸做的，雖然它們不是相同的切割類型。斜切的切口隻是一個成角度的橫切。您可能正在切割45度，而不是做90度的切割。為此，您不必調整刀片本身。隻需使用鉛筆和適當的測量工具製作標記以確保您達到正確的角度。然後，讓成角度的斜切切割，就像你一樣是正常的橫切。
對於切割斜麵，您必須調整刀片的角度。如果需要45度斜麵，請將鋸片調整為45度角，然後按照否則將切割切割。
Safety When Cutting 2x4s with a Circular Saw
Below are a few safety tips you should keep in mind when working on this task:
- Always use proper safety equipment, which includes safety goggles, a mask, and ear protection
- 在開始之前，請務必檢查您的鋸是否處於工作狀態
- Make sure that you hold the saw properly
- 始終使用正確的刀片深度來刪除
- 隻使用鋒利和狀況良好的刀片
- Never try to cut more than your arms can reach
- Always keep live electrical cords out of the way

避免，提示和技巧的錯誤
最後，這裏有一些讓你的工作更輕鬆的提示：
- Using the right blade for the job at hand is key; you don’t use the same blade for softwood as for hardwood, for example
- If you are a beginner, using clamps as opposed to manually holding the piece down is recommended
- 在進行斜切和斜麵切割時，始終使用適當的測量工具來確保您獲得角度
- Always make sure the blade is running at full speed before making a cut
Summary
正如您可以看到的,一個圓鋸是一個非常多才多藝的tool for cutting 2x4s. You can make rip cuts, crosscuts, bevel cuts, and miter cuts.
隻要您遵循上麵概述的提示，您就不會有任何問題。
