這paddle switch makes it safe and convenient.

它有一個無工具輪式改變係統。

Cons of the Product
While this product has good points, it does have some minor drawbacks.
它是固定速度。
With 11,00 RPM, unfortunately, it is not a variable-speed unit. You might find it useful for general angle grinder applications and not for delicate ones. This may be a con for some folks, if you are looking for an angle grinder to tackle a complete range of tasks.
對於某些用戶來說，該工具可能有點沉重。
在大約六磅，這個工具對那些不超過四磅的人的人並不友好。盡管如此，如果耐用性是您正在尋找的，那麼增加的重量可以看出比孔更高。
What Are the Alternatives?
這re are also alternatives for the DeWalt DWE402 out there if you’re looking for similar angle grinders. For instance, theBlack＆Decker BDEG400has a similar 4 1/2-inch-sized wheel however, its side handle has notably more positions – up to three. It also comes with a wheel guard and you might like this unit more if you want a lighter weight (it weighs in at just about four pounds).
Another similar angle grinder to the DeWalt mentioned above, is theMakita 9557PBX1這也具有用於安全的槳式開關機構。它們都有4個1/2英寸尺寸的輪子。兩者之間的顯著差異是重量，因為makita工具隻有四個半磅。盡管如此，它們都有11,000 rpm的速度。

整個DEWALT DWE402is a respectable choice for most tasks. This can be a go-to power tool if you’re looking to cut metal, redoing your tiles, or working on bathroom projects and the like. But, do note that it does not have variable speed.
