Built from premium grade high speed steel (HSS) with a black and bright surface treatment, these drills are designed for contractors and trades professionals drilling low to medium tensile strength materials. The set covers 9\/16\" through 1\" in 1\/16\" increments, providing eight commonly needed sizes in a single package. Three flats ground onto each shank ensure a secure, slip-resistant grip in handheld power tools, while a common flute and overall length across all eight bits minimizes setup time during tool changes.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eDRILLCO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem #\u003c\/td\u003e\n\u003ctd\u003e1000F8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e045997490595\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePieces\u003c\/td\u003e\n\u003ctd\u003e8 PC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize Range\u003c\/td\u003e\n\u003ctd\u003e9\/16\" to 1\" by 16ths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShank Type\u003c\/td\u003e\n\u003ctd\u003e1\/2\" reduced shank with 3-flats\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoint Angle\u003c\/td\u003e\n\u003ctd\u003e118° general purpose point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePremium grade HSS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface Treatment\u003c\/td\u003e\n\u003ctd\u003eBlack and bright for higher lubricity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eDrilling large diameter holes, Drilling in low to medium strength materials, Making holes with fixed spindle machines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnical Tips\u003c\/td\u003e\n\u003ctd\u003eSpeed, feed, and lube are all critical to cutting tool performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eAvailable Items\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eItem #\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1000F8\u003c\/td\u003e\n\u003ctd\u003e8PC S\u0026amp;D FLAT DRILL SET 9\/16-1 BY 16THS\u003c\/td\u003e\n\u003ctd\u003e9\/16\" to 1\" by 16ths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eUnlike standard jobber-length drills limited to the chuck's native capacity, the 1000F series uses a 1\/2\" reduced shank to unlock large-diameter drilling on any standard 1\/2\" portable drill without requiring a larger chuck or specialized equipment.
