Specification Brand : Drill America BulletPoint1 : High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance BulletPoint2 : Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge 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 : Ideal for drilling in low and medium tensile strength materials BulletPoint6 : Made in the USA Color : Round CuttingAngleString : 118.0 degrees ExternallyAssignedProductIdentifier1 : 887861227490 ExternallyAssignedProductIdentifier2 : 0887861227490 ExternallyAssignedProductIdentifier3 : 00887861227490 FinishType : Black Oxide GpsrSafetyAttestation : 1 IncludedComponents : 12 Drill Bits ItemName : Drill America 17/64" High Speed Steel Reduced Shank Drill Bit with 1/4" Shank (Pack of 12), D/ARSD Series ItemPackageDimensions_Height : 2 inches ItemPackageDimensions_Length : 6 inches ItemPackageDimensions_Width : 4 inches ItemPackageQuantity : 1 ItemTypeKeyword : reduced-shank-drill-bits Manufacturer : Drill America Material : High-Speed Steel MfgSeriesNumber : 790 ModelNumber : D/ARSD17/64P12 NumberOfFlutes : 2 NumberOfItems : 1 PartNumber : D/ARSD17/64P12 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.
