Manufactured in the United States from premium grade high speed steel (HSS), this set covers sizes from 9\/16\" to 1\" by 16ths, providing eight commonly needed diameters in a single kit. It is ideally suited for contractors and trades professionals drilling large-diameter holes in low to medium tensile strength materials, as well as for use with fixed spindle machines. A common flute and overall length across all bits in the set minimizes adjustment time during tool changes on the job site.\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\u003e1000A8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e045997490434\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\u003ePiece Count\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\u003c\/td\u003e\n\u003ctd\u003e1\/2\" reduced shank\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\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\u003e1000A8\u003c\/td\u003e\n\u003ctd\u003e8PC S\u0026amp;D DRILL BIT 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 that are limited by chuck capacity, the 1000A series uses a 1\/2\" reduced shank to unlock large-diameter drilling on any standard 1\/2\" portable drill — no specialized equipment required.
