This 4-piece countersink and chamfer drill bit set is designed for clean deburring, beveling, and countersinking of circular holes on various soft metal and plastic surfaces. Each bit is made from HSS4241 high-speed steel with a titanium coating for enhanced durability, sharpness, and heat resistance.
Perfect for tradespeople, metalworkers, and DIY users, this set supports a wide range of applications including deburring aluminium, mild steel, PVC panels, wood, and plastic boards. The internal crosshole design improves chip removal and reduces clogging during cutting, delivering smoother, more efficient hole finishes.
