Specification Brand : Mollom BulletPoint1 : 【Product Size】Drilling diameter:21mm | 13/16", Round Shank Dia.: 8mm | 5/16", Drilling depth: 60mm | 2-3/8", Total length: 94mm | 3-11/16" BulletPoint2 : 【High Quality】Positioning drills and blades are made of YG8, hardness ≥ 91HRA, bending strength up to 2200N/cm2, resharpenable. The shank rod is made of No. 45 steel, heat-resistant and corrosion-resistant. After quenching, the hardness is extremely high, effectively avoiding shank bending during use BulletPoint3 : 【2.00mm Super Thick Blade】Adopts industrial grade 2.0mm thickness YG8 blade, which extends the service life by 10 times compared to 1.3mm thick blade BulletPoint4 : 【Super Accurate】We use a fully automated production line, the product accuracy is up to 99%, the error of drilling holes is within 0.1mm, it is a good choice for high precision drilling work (for hardwoods choose the corresponding size, for softwoods choose a size smaller by 0.2-0.5mm) BulletPoint5 : 【Note】 The drilling process needs to be kept vertical and it is recommended that a tool such as a vise be used to keep the material stable so that a smooth, accurately sized hole can be obtained. Set slow drilling speed till the drill bit is completely located, then gradually accelerate speed. The rotational speed is controlled at 2200~2500RPM for better effect BulletPoint6 : 【Widely Applications】 The Forstner hole saw is perfect for wood,plastic,plywood,solid wood boards,MDF,plastics,furniture,door hinge,desk,etc.Note: Can not drill metal and non-ferrous metal BulletPoint7 : 【Warm Tips】For large-size Forstner drill bits (≥60mm), it is best to use machines with good fixation performance for drilling operations, such as drill presses, bench drills, vertical drill presses and vertical electric drills, etc. If you must use a hand electric drill to operate , be sure to use a high-power electric hand drill, and it is best to use it with a vise with good fixation effect. Otherwise, good hole opening effect will not be achieved Color : Black CustomerPackageType : Standard Packaging CuttingAngleString : 90 degrees ExternallyAssignedProductIdentifier1 : 738685361115 ExternallyAssignedProductIdentifier2 : 0738685361115 ExternallyAssignedProductIdentifier3 : 00738685361115 ExternallyAssignedProductIdentifier4 : 0664252013531 ExternallyAssignedProductIdentifier5 : 00664252013531 FinishType : Uncoated GpsrSafetyAttestation : 1 IncludedComponents : 1xForstner Drill Bit ItemName : Mollom 13/16" (21mm) Forstner Drill Bit for Precise Woodworking with Durable YG8 Carbide Thickness of 2.0mm,This Hinge Cutter Tool is Ideal for Hard Wood, Plastic, Plywood ItemPackageDimensions_Height : 11.6 centimeters ItemPackageDimensions_Length : 3.2 centimeters ItemPackageDimensions_Width : 3.3 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : forstner-bits Manufacturer : Mollom Material : 2.0mm YG8 Carbide Blade MfgSeriesNumber : 537.300.31 ModelNumber : FDB01021 NumberOfFlutes : 2 NumberOfItems : 1 NumberOfPieces : 1 PackageLevel : unit PartNumber : FDB01021 ProductDescription : MOLLOM 13/16" (21mm) Forstner Drill Bit for Precise Woodworking with Durable YG8 Carbide Thickness of 2.0mm,This Hinge Cutter Tool is Ideal for Hard Wood, Plastic, Plywood ProductSiteLaunchDate : 2023-11-24T06:16:35.644Z Size : 21mm | 13/16" StreetDate : 2015-03-04T00:00:01Z Style : 21mm | 13/16" SupplierDeclaredDgHzRegulation : not_applicable SurfaceRecommendation : Perfect for Cutting Wood, Plywood, Solid Wood Boards, MDF, Plastics, etc UnitCount : 1 UnspscCode : 27112700
