Each bit is manufactured from cobalt high-speed steel, which provides superior heat and wear resistance compared to standard HSS, making the set well suited for drilling into hard metals, stainless steel, cast iron, and other demanding materials. The 135-degree split-point tip reduces walking on contact, enabling faster penetration without a center punch on most metal surfaces. All 26 bits feature a straight shank and a bright uncoated finish. The set is intended for licensed machinists, maintenance technicians, and heavy-duty metalworking applications.\u003c\/p\u003e\u003cp\u003eThis set is sized for metalworking and multipurpose drilling tasks in both shop and field environments. The full A-through-Z letter series covers fractional-adjacent diameters commonly required for tapping and reaming operations in industrial maintenance, fabrication, and production settings. The included storage case keeps bits organized and protected between uses, supporting efficient workflow on the job site or at the bench.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance in hard-metal drilling\u003c\/li\u003e\n\u003cli\u003e135-degree standard split point reduces bit walking and improves penetration speed\u003c\/li\u003e\n\u003cli\u003eFull letter series A through Z  -  26 bits in one set\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish  -  no coating to chip or peel under heavy use\u003c\/li\u003e\n\u003cli\u003eIncludes metal or plastic storage case for organization and transport\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill presses, hand drills, and mill-drill machines accepting straight shank bits.
