Specification Brand : MICHIGAN DRILL 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 : These round shank tools have flats ground onto three sides to reduce slippage of the bit when used in drill chucks BulletPoint4 : Reverse (left hand) spiral flute tools push chips forward into the cut as they work, so they won't pull thin material towards the tool as it cuts and are useful for interrupted cuts such as keyways BulletPoint5 : Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction ExternallyAssignedProductIdentifier : 5479228777004 ExternallyAssignedProductIdentifier1 : 695499496559 ExternallyAssignedProductIdentifier2 : 0695499496559 FinishType : Black Oxide GpsrSafetyAttestation : 1 ItemName : Michigan Drill 535R Series High-Speed Steel Aligning Reamer, Left Hand Spiral Flute, Round with Flats Shank, Black Oxide Finish, 5/16" Size ItemPackageDimensions_Height : 24.3 centimeters ItemPackageDimensions_Length : 2 centimeters ItemPackageDimensions_Width : 2.5 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : chucking-reamers Manufacturer : Michigan Drill Corporation Material : High-Speed Steel MeasurementSystem : Inch MfgSeriesNumber : 535R ModelNumber : 535R 5/16 NumberOfFlutes : 3 NumberOfItems : 1 PartNumber : 535R 5/16 ProductDescription : Super Tool, Inc. 56556450 0.645" Diameter Carbide Tipped Chucking Reamer, Made in the USA ProductSiteLaunchDate : 2013-10-02T08:00:01.000Z Size : 5/16" StreetDate : 2017-03-12T00:00:01Z SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 1 UnspscCode : 27111700
