These jobber length bits are manufactured to National Aerospace standard 907 and are designed for higher red hardness than standard high-speed steel, which makes them suited to drilling stainless steel, high carbon steel, and other tough metals where durability and cutting speed matter.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCobalt construction:\u003c\/strong\u003e Heat resistant cobalt steel permits higher red hardness so the bit maintains cutting edge under heavy use and higher speeds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGold oxide finish:\u003c\/strong\u003e A thinner oxide surface treatment reduces surface corrosion and provides visual identification without changing cutting performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRound shank:\u003c\/strong\u003e Round shanks fit a wide variety of toolholding systems for use in drills, drill presses, and stand-mounted tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral flute geometry:\u003c\/strong\u003e Right-hand spiral flutes evacuate chips up and out of the hole to reduce clogging while drilling deeper cuts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing standard:\u003c\/strong\u003e Made to National Aerospace standard 907, offering consistent geometry and tolerance suitable for demanding metalworking tasks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJobber length:\u003c\/strong\u003e General-purpose length balances rigidity and reach for common shop tasks on metal and thick stock.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese drill bits are aimed at hobby machinists, fabrication shops, and maintenance technicians who frequently drill hard materials like stainless steel, titanium, or high carbon alloys and need bits that tolerate higher speeds and sustained heat.
