This beyond specific differences in brand of said tools such as the Journeyman series or D2000-48 of Klien that are hardened to stay sharp longer than something otherwise just off the shelf. Speaking of this concept of quality but in a different sense. Drill bits. What is the difference in them say between solid carbide, high speed steel & others by way of drilling speed and what you drill? What’s the difference in surface treatments for general purpose use such as on wood, aluminum & steel overall use? Do you say need a TiALN coated bit persay? What’s the difference in cutting oils for use on steel verses aluminum? Most important, what is the common drill bit angle: 118 degrees or 135 degrees & what’s the benefits or disadvantages of each?
