Crafted with M35 HSSCO high-speed steel and finished with a distinctive black and gold polish, these bits balance hardness and toughness to resist wear while maintaining a reliable cutting edge. The set features a 5\/8 inch diameter and 6 inch overall length, offering reach for thicker materials, with a 1\/2 inch reduced shank to boost compatibility with a wide range of toolholding systems. This combination of materials and finish aims to enhance lubricity and coolant retention near the cutting edge during use.\u003c\/p\u003e\n\n\u003cp\u003eThe 135-degree split point supports quick, accurate starts with minimal wandering, while the right-hand spiral design helps chip evacuation to reduce buildup inside the cut. When used in a typical clockwise operation, the geometry works with common drilling workflows to maintain control and predictability across multiple metals. This set is well suited for routine tasks in stainless steel, cast iron, zinc alloys, copper, and other common metalwork scenarios.\u003c\/p\u003e\n\n\u003ch3\u003eWhat you get and how it helps\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThree bits included: 5\/8 inch diameter for standard holes, 6 inches long for reach, and a 1\/2 inch reduced shank for broad compatibility.\u003c\/li\u003e\n  \u003cli\u003eBalanced hardness and toughness to support longer tool life and cleaner entry under typical drilling conditions.\u003c\/li\u003e\n  \u003cli\u003eCoolant-friendly surface with specialized pockets to help maintain edge efficiency during metal cutting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePerformance highlights and best-use scenarios\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVersatile across metals: suitable for stainless steel, cast iron, zinc alloys, copper, and other common alloys encountered in workshops.\u003c\/li\u003e\n  \u003cli\u003eCentering and penetration: 135-degree point aims for quick, precise starts with minimal wandering.\u003c\/li\u003e\n  \u003cli\u003eChip control: spiral flute design reduces clogging and improves cutting efficiency when drilling through metal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTips for best results: use steady feed pressure, moderate speeds, and appropriate lubrication to maximize edge life.
