Specification Brand : Drillco BulletPoint1 : High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance BulletPoint2 : Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools BulletPoint3 : Round shanks allow use with a wide variety of toolholding systems BulletPoint4 : When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging BulletPoint5 : 5 Piece reduced shank S and D drill set BulletPoint6 : Made in the USA Color : Round CuttingAngleString : 118.0 degrees ExternallyAssignedProductIdentifier1 : 045997490618 ExternallyAssignedProductIdentifier2 : 696738511088 ExternallyAssignedProductIdentifier3 : 0045997490618 ExternallyAssignedProductIdentifier4 : 0696738511088 ExternallyAssignedProductIdentifier5 : 00045997490618 FinishType : Black and Gold Oxide GpsrSafetyAttestation : 1 IncludedComponents : 12 Drill Bits ItemName : Drillco 1000N Series Nitro 5 Piece High-Speed Steel Reduced Shank Drill Bit Set, Black and Gold Oxide Finish, Round Shank, Spiral Flute, 118 Degrees Split Point, 9/16" - 1" in 1/8" increments ItemPackageDimensions_Height : 5.842 centimeters ItemPackageDimensions_Length : 21.336 centimeters ItemPackageDimensions_Width : 16.256 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : reduced-shank-drill-bits Manufacturer : Drillco Cutting Tools Material : High-Speed Steel MfgSeriesNumber : 790 ModelNumber : 1000N5 NumberOfFlutes : 2 NumberOfItems : 1 PartNumber : 1000N5 ProductDescription : Specifications: -Cutting Edge Diameter: 14mm -Shank Diameter: 1/2 inch -Cutting Edge Length: 2.22 inch -Total Length: 5.9 inch -Split Point: 135°
Material: -9341 high speed steel, after heat treatment, has excellent hardness, making it suitable for use in high-friction environments. -Drill bits made from high speed steel can effectively resist wear, extending their service life and making them suitable for drilling metals and other hard materials. -9341 Reduced Shank Drill Bit can drill a variety of materials, including stainless steel, carbon steel after heat treatment, iron, aluminum alloy, copper, wood, plastic, etc., with strong adaptability, also including auto repair, modification, appliance installation repair
Surface Treatment: -The black nitriding layer formed during the nitriding process effectively resists oxidation and corrosion, making it suitable for use in harsh environments and reducing maintenance frequency, provides lubricity, while the small pore structure effectively retains coolant, enhancing the cooling effect during the cutting process and reducing wear
TIP: -When ues reduced shank drill bit, it's important to maintain a 90-degree vertical angle to ensure precision and accuracy. -For power drills, it's recommended to use a model with a power rating of 750W or higher. -Use water or coolant to lower the temperature and prevent the drill bit from overheating, especially when drilling stainless steel materials. -For metals with high hardness and dense grain structure, use a slower drill speed than normal drilling, and cooling the workpiece will yield better results. -When machining thick workpieces, if there are issues with chip removal, promptly clear the debris.
