Covering a size range of 1\/16\" to 1\/2\" by 64ths, this 29-piece set provides comprehensive coverage for the most common hole sizes encountered on the job. The 135° split point geometry and black oxide surface treatment make these drills well-suited for heavy-duty drilling applications, including stainless steel and tougher ferrous materials. Speed, feed, and lubrication are all critical to cutting tool performance and should be optimized for each application.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\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\u003e400EW29\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003e045997491400\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\u003e29 PC\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\u003e135° Split Point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eGeneral Purpose High Speed Steel (HSS)\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 medium and high strength materials; heavy-duty 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\n\u003ctr\u003e\n\u003cth\u003eItem #\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e400EW29\u003c\/td\u003e\n\u003ctd\u003e29PC HD DRILL PAL 1\/16-1\/2 BY 64THS - SET\u003c\/td\u003e\n\u003ctd\u003e1\/16\" – 1\/2\" by 64ths\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eCompared to standard 118° conventional-point HSS drills, the 400E set's 135° split point reduces thrust requirements and minimizes walking, making it more effective on curved surfaces and harder materials where a conventional point would skate.
