Description
This is a 29-piece drill bit set composed entirely of premium high-speed steel (HSS), engineered for heavy-duty industrial and professional drilling tasks. Each bit in the set features a 3-flat shank design to prevent slippage in the chuck, ensuring precise and secure engagement. All bits have a 135° split point tip that minimizes walking and enhances centering on the material surface. The bits are coated with black oxide and finished with a gold layer, providing corrosion resistance and reduced friction to extend tool life. This set includes a broad range of sizes covering common mechanical length drill bit diameters used in metalworking and fabrication.
