8.8mm OSG ADF-2D Drill Bit

High-Performance Carbide Flat Drills, Ideal for Diverse Applications. Traditional flat hole machining required an end mill and a drill, but the A Brand ADF enables one-step drilling, simplifying machining time and tool management. Suitable for various applications like inclined surfaces, curved surfaces, counterboring, eccentric holes, and thin plates. The EgiAs Coating suppresses friction, prevents breakage, and features a unique end cut geometry that reduces cutting force for stable machining. It also boasts a wide chip room for smooth chip evacuation. Key dimensions include: Diameter (Metric) 8.8, Diameter (Inch) 0.34646, Flute Length (Metric) 38, Neck Length (Metric) 40, Overall Length (Metric) 80, Shank Diameter (Metric) 8. Cutting Diameter Tolerance: +0 / -0.022 (Metric), +0 / -0.0009 (Inch), Specification h8. Substrate: Carbide, Surface Treatment: EgiAs. Length of Cut: STUB, Drilling L/D Ratio: 2, Helix Angle: 20 degrees, Point Angle: 180 degrees, Helix Direction: RH, Cutting Direction: RH, Coolant Thru: No, Number of Flutes: 2, Shank Tolerance: h6, Type: 2. Includes DXF and STP drawings. Note: Sizes smaller than 2mm available with IchAda coating, sizes 2mm and larger with EgiAs coating.
