The self-centering 135-degree split point reduces the need for pilot holes and produces smaller chips to minimize clogging. A gold oxide finish acts as a lubricant and adds wear resistance, while the round shanks enable compatibility with many tool holding systems.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSelf-centering 135-degree split point improves initial bite\u003c\/li\u003e\n  \u003cli\u003eSmaller chips reduce debris buildup in the hole\u003c\/li\u003e\n  \u003cli\u003eExtended tool life versus conventional high-speed bits\u003c\/li\u003e\n  \u003cli\u003eRound drill index combines form and function for easy transport\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMaterials, applications, and performance\u003c\/h3\u003e\n\u003cp\u003eDesigned to handle high-strength alloys, this set is well-suited for stainless steel, Inconel, and titanium work.
