Specification Brand : TopHomer BulletPoint1 : 【Parameter Information】Cutting angle 135°, shank diameter 1/2”, shank type tri-flat. Cutting edge diameter, cutting edge length and total length are different for each product. Check out the size chart for specific information. Please check the size you need before purchasing BulletPoint2 : 【Reliable Material】This reduced shank drill bit is made of 63-65HRC HSS-Co, balancing hardness and impact resistance, with stable cutting edge wear resistance. The surface is treated with nitrided black and baked yellow to absorb lubricants and reduce drilling friction, suitable for wood, plastic and metal (such as stainless steel, aluminum, copper). It is recommended to evaluate the wear condition every 3-6 months for high-frequency use and replace it in time to maintain machining efficiency BulletPoint3 : 【Tri-flat Shank Design】Tri-flat shank construction provides more efficient torque transfer and prevents bit slippage. 1/2” shank diameter of the heavy duty metal drilling is compatible with most industrial equipment (e.g., bench drills, milling machines) and is suitable for machining hard metals and automotive repair scenarios BulletPoint4 : 【135° Opening Angle】135° opening angle with helical flute structure effectively guides debris away from the drill and reduces axial pressure during machining. This design of the woodworking drill bit reduces the probability of burrs on the hole edge and reduces operation fatigue, especially suitable for continuous drilling BulletPoint5 : 【Maintenance And Operation Recommendations】It is recommended to use cutting fluid when machining metal to reduce the cutting edge temperature and increase the life of the reduced shank twist drill bit. After use, it is recommended to remove debris immediately and wipe the shank and cutting edge with a soft cloth soaked in alcohol. If the cutting edge is found to be dull or cracked, it should be replaced promptly to avoid precision deviation or equipment damage Color : Copper ExternallyAssignedProductIdentifier : 4507502568244 IncludedComponents : Drill Bit ItemName : TopHomer Reduced Shank Drill Bit Set- 1/2” Shank Drill Bit, M35 HSS-Co Black and Gold Nitrided Finish, 135 Degree Split Point, Ideal for Wood, Plastic and Metal,Cutting Edge Diameter 63/64" ItemPackageDimensions_Height : 4 centimeters ItemPackageDimensions_Length : 17 centimeters ItemPackageDimensions_Width : 14 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : reduced-shank-drill-bits Manufacturer : TopHomer Material : HSS-Co ModelNumber : LSW2504237 NumberOfItems : 1 NumberOfPieces : 1 PartNumber : CJY-TH-250423E8 ProductDescription : Feature: 【Parameter Information】Cutting angle 135°, shank diameter 1/2”, shank type tri-flat.
