Each bit features a 118° conventional point for rapid penetration and a black oxide surface treatment that reduces friction, prevents chip welding, improves chip flow, and increases abrasion resistance. The set is manufactured in the United States and is suited for contractors and trades professionals who need a reliable, broad-range drill set for everyday drilling tasks. Speed, feed, and lubrication are all critical to cutting tool performance with this series.\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\u003e100SE29\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e045997490670\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\u003eSet Size\u003c\/td\u003e\n\u003ctd\u003e29 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize Range\u003c\/td\u003e\n\u003ctd\u003e1\/16\" to 1\/2\" by 64ths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePoint Angle\u003c\/td\u003e\n\u003ctd\u003e118° conventional point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eGeneral purpose HSS (High Speed Steel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface Treatment\u003c\/td\u003e\n\u003ctd\u003eBlack oxide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength Type\u003c\/td\u003e\n\u003ctd\u003eJobber length\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eDrilling holes in low strength materials, general purpose drilling\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\u003e100SE29\u003c\/td\u003e\n\u003ctd\u003e29PC DRILL BIT SET 1\/16-1\/2 BY 64THS\u003c\/td\u003e\n\u003ctd\u003e1\/16\" to 1\/2\" by 64ths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe 100SE series distinguishes itself from bright-finish or uncoated alternatives through its black oxide surface treatment, which actively reduces friction and heat damage, prevents chip welding, and extends tool life compared to uncoated HSS bits.
