The OSG 8682430 is a solid carbide jobber-length drill bit designed for precise, high-performance drilling in demanding production and maintenance environments. Built with a 140-degree split point and a WXL coating, this drill is engineered to reduce thrust, minimize walking at entry, and extend tool life in hard or abrasive workpiece materials. The 4.30 mm diameter corresponds to 0.1693 decimal inch. With a spiral flute design and coolant-through capability, it supports high-speed drilling strategies where chip evacuation and heat management are critical. Machinists, tool-and-die workers, and maintenance technicians working on CNC or manual equipment will find this a direct fit for precision hole-making operations.
This drill bit is suited for metalworking applications including production drilling, fixture work, and precision repair operations where dimensional accuracy and hole quality matter. The 5xD flute-to-diameter ratio and 39.00 mm flute length provide adequate chip clearance for moderate-depth holes in steel, stainless, cast iron, and similar materials. It is sold individually and fits within the 4.00 mm to 5.00 mm drill bit size range, making it a standard selection when a 4.30 mm or 0.1693-inch finished hole is required.
Designed as an OEM-style jobber drill for use in standard drill chucks, ER collets, and hydraulic toolholders accepting a straight-cylindrical shank in the 4.00 mm to 5.00 mm diameter range.
Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool handling and machine tool operation. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the drill. Secure the shank fully within the chuck or collet to the recommended engagement depth to prevent pullout under cutting load. Inspect the cutting edges and coating condition before each use and remove from service at the first sign of chipping or excessive wear.
