Why Choosing Between Standard Cut and Double Cut Matters
Picking the right cut type can seriously impact your work quality. The Standard Cut offers a single set of flutes that remove material quickly and cleanly, perfect for softer metals or wood. The Double Cut has two crossed sets of flutes, giving a shearing action that creates finer finishes and less vibration—great for harder materials. Imagine painting a wall with a broad brush for fast coverage (standard cut) versus a fine roller for smooth, even detail (double cut). Knowing which to use helps you nail that flawless finish every time.
