6.8mm 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. EgiAs Coating suppresses friction, prevents breakage, and offers a unique end cut geometry that reduces cutting force for stable machining. It also features a wide chip room for smooth chip evacuation. Key dimensions include: Diameter - Metric (D) 6.8, Diameter - Inch (D) 0.26772, Flute Length - Metric (FL) 30, Neck Length - Metric (L1) 32, Overall Length - Metric (L) 70, Shank Diameter - Metric (d) 6. Cutting Diameter Tolerance is +0 / -0.022 (Metric) or +0 / -0.0009 (Inch), with a Cutting Diameter Tolerance Specification of h8. The Substrate is Carbide, and the Surface Treatment is EgiAs. It has a Length of Cut - Specification of STUB, Drilling L/D Ratio (xD) of 2, Helix Angle - Degree of 20, Point Angle - Degree (α) of 180, Helix Direction of RH, and Cutting Direction of RH. It does not require Coolant Thru, has 2 Number of Flutes, and a Shank Tolerance of h6. It's a Type 2 drill with DXF and STP drawings available for download. Note: Sizes smaller than 2mm are available with IchAda coating, while sizes 2mm and larger use EgiAs coating.
