Lathe vs. Mill: What's the Difference and Which is Better? - metal lathe and milling machine
Micro deep hole drills allow users to meet some of the most challenging application requirements by drilling 20-80xD. Special equipment and tooling, such as an EDM machine or gun drill, is no longer needed to drill prototype and/or production deep holes in most common and exotic materials.
Center point drill bitssizes
5/8″ High Speed Tool Steel Brad Point Drill Bit. Fast flute for great chip removal and less chip burn. 3/8″ Shank. Great for soft, hard, exotic, veneered and laminated wood.
Micro deep hole drills are manufactured using an ultra-fine carbide grain structure giving them a small amount of flexibility while maintaining the rigid characteristics of carbide. The modern AlCrN based coating is capable of withstanding materials such as tool steel, titanium, Inconel, and stainless steel.
