Specification Brand : Drill America 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 : 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 : Manufactured to National Aerospace standard 907 CuttingAngleString : 135.0 degrees ExternallyAssignedProductIdentifier1 : 887861307567 ExternallyAssignedProductIdentifier2 : 0887861307567 FinishType : Silver FinishType1 : Gold FinishType2 : black IncludedComponents : Drill Bit with 1/2" Shank ItemDisplayDimensions_Height : 8 inches ItemDisplayDimensions_Length : 8 inches ItemDisplayDimensions_Width : 4 inches ItemName : Drill America 18.50mm Reduced Shank Cobalt Drill Bit with 1/2" Shank, D/AMMCO Series ItemPackageDimensions_Height : 2 inches ItemPackageDimensions_Length : 6 inches ItemPackageDimensions_Width : 4 inches ItemPackageQuantity : 1 ItemShape : Round ItemTypeKeyword : reduced-shank-drill-bits Manufacturer : Drill America Material : Cobalt ModelNumber : D/AMMCO18.50 NumberOfBoxes : 1 NumberOfItems : 1 NumberOfPieces : 8 PackageLevel : unit PartNumber : D/AMMCO18.50 Pattern : 135 split point reduced-shank drill bit ProductDescription : Reaper Cobalt Drill Bits are constructed of a patented M42+ alloy consisting of 8% cobalt and high-molybdenum, increasing drill bit strength, rendering them super-friction-resistant and allowing for greater heat resistance when drilling the hardest and most demanding materials. These bits will cut more holes than most of our competitors, making the need to re-sharpen less frequent. Reaper Cobalt Drill bits feature a 135 degree split point eliminating the need for pilot hole predrilling or starter punching and making them particularly successful in cutting holes in harder grades of stainless steel and other material higher up on the Rockwell chart. Shanks have 3 machine-ground flats, which prevent slippage in drill chucks.
