Two flute design provides a smoother cutting, allows the material particles escape easily for a much more clean drilling operation, can be used on electrical drill, cordless drill BulletPoint5 : WELL DESIGNED: Provides stability during the drilling process, minimizes noise and vibration, which improves work efficiency and safety, bringing a smoother and quieter drilling experience BulletPoint6 : Supports 36V BulletPoint7 : Magnetic BulletPoint8 : Made in Japan BulletPoint9 : RoHS 10 Substances Color : Black(Spiral Grooved) CompatibleFastenerDescription : 0.25 inches CustomerPackageType : Standard Packaging CuttingAngleString : 118 degrees DriveSystem : Outside Hexagon ExternallyAssignedProductIdentifier : 4907587347435 ExternallyAssignedProductIdentifier1 : 799670742937 ExternallyAssignedProductIdentifier2 : 0799670742937 FinishType : Polished GpsrSafetyAttestation : 1 IncludedComponents : M2 Step Drill Bit ItemDisplayDimensions_Height : 2.5 centimeters ItemDisplayDimensions_Length : 7.6 centimeters ItemDisplayDimensions_Width : 16.3 centimeters ItemDisplayWeight : 38 grams ItemLength : 3.2 inches ItemName : Lichamp Unibit Step Drill Bit for Metal, Genuine M2 Drill Stepper Bit for Hard Metal Heavy Duty, 12 Sizes from 3/16" to 7/8", Dual Straight Grooved with Hex Drive, A3BK ItemPackageDimensions_Height : 14.9 centimeters ItemPackageDimensions_Length : 4.3 centimeters ItemPackageDimensions_Width : 8.8 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : step-drill-bits Manufacturer : Lichamp Material : M2 High Speed Steel Material1 : Stainless Steel Material2 : High Speed Steel Material3 : Brass ModelName : SS1620 ModelNumber : SDB-A301BK NumberOfFlutes : 2 NumberOfItems : 1 NumberOfPieces : 1 PartNumber : SDB-A301BK ProductDescription : Typical Data / Physical Properties: Brand: Lichamp Type: M2 Step Drill Bit Material: M2 High Speed Steel Thread Style: Right Finish Type: Polished Color: Silver Number of Steps: 12 Style: Dual-Flute Step Bits Cutter Geometry: Dual-Flute Angle Point: 118 Degree Flute Type: Straight Shank Type: Hex Package: Plastic Case Package Quantity: 1 Environment: Indoor and Outdoor Size: 12 Sizes from 3/16" to 7/8" Hole Diameter: 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8"
Features: 1. Genuine M2 HSS ensures durability and sharpness which can reduce the friction and run cooler. 2. Drills holes of various sizes without changing bits, Smoother and rounder holes, Prevents metal scurf from flying around for improved safety. 3. 118 degrees split point tip provides faster cutting and prevent sliding while increasing the wear resistance. 4. Double flutes design allows the particles escape easily for a clean drilling operation. 5. Great for sheet metal, aluminum sheets, wood chips, plastic and wood board. It's a perfect choice for DIY and engineering use. 6. Come with a small plastic box for easy storage and organizing.
Tips: 1. Not compatible with hammer drill. 2. Please do not set drilling speed too high to avoid damages to cutting edge. 3. Please use water to cool down the bit after in operation for a while to improve service life. 4. It is recommended to oil the bit before every use. 5. Please drill a smaller hole to make drilling smoother. 6. The thickness shall NOT exceed the height of each increment of the step drill bit.
