Specification Brand : MICHIGAN DRILL BulletPoint1 : Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys BulletPoint2 : Round shanks allow use with a wide variety of toolholding systems BulletPoint3 : When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging BulletPoint4 : Heavy web 8 percent cobalt content permits use at higher speeds in hardened stainless heat treated and high temperature alloys BulletPoint5 : 1/2-inches standard shank diameter Color : Multi Configuration : configuration CustomerPackageType : 1 CuttingAngleString : 135.0 degrees ExternallyAssignedProductIdentifier1 : 695499091754 ExternallyAssignedProductIdentifier2 : 0695499091754 ExternallyAssignedProductIdentifier3 : 00697334211761 FinishType : cobalt GpsrSafetyAttestation : 1 IncludedComponents : (1) Drill Bit ItemName : Michigan Drill 303C Series Cobalt Steel Reduced Shank Drill Bit, Round Shank, Spiral Flute, 135 Degrees Notched Point, 49/64" Size (Pack of 1) ItemPackageDimensions_Height : 8.87 inches ItemPackageDimensions_Length : 19.31 inches ItemPackageDimensions_Width : 11.43 inches ItemPackageQuantity : 1 ItemShape : Rectangular ItemTypeKeyword : reduced-shank-drill-bits Manufacturer : Michigan Drill Corporation Material : Cobalt Steel Material1 : High Carbon Steel Material2 : Blend Material3 : Blend Material4 : Blend Material5 : Blend MfgSeriesNumber : 303C ModelNumber : 303C 49/64 NumberOfFlutes : 2 NumberOfItems : 1 NumberOfPieces : 1 PackageLevel : unit PartNumber : 303C 49/64 Pattern : Solid ProductDescription : Specifications: -Cutting Edge Diameter: 29/64 inch -Shank Diameter: 3/8 inch -Flute Length: 2.8 inch -Total Length: 6 inch -Split Point: 135° -Material: 4341 high-speed steel
1. 341 high-speed steel maintains excellent corrosion resistance and high strength, enabling effective drilling of medium-to-high hardness metals. The nitriding black actively resists oxidation and corrosion to extend drill bit durability.
2. 135° split-point tip, offers exceptional processing stability, for harder materials. Effectively minimizes the risk of cutting edge chipping, which enhances drilling efficiency and improves hole quality
3. Suitable for soft metal and woodworking projects, widely used in daily operations such as home maintenance, suitable for processing medium hardness materials, such as copper, aluminum, iron, plastic, and wood
4. About the relationship between the bit and the speed, larger bits need lower RPM, smaller bits require higher RPM, and harder materials require lower RPM for better cutting performance and longer drill life.
5. When using a reduced shank drill bit, it's crucial to maintain a 90-degree vertical angle for precision and accuracy. Additionally, water or coolant should be used to reduce temperature and prevent overheating. This helps ensure optimal performance and extends the lifespan of the drill bit.
