Countersink: 3" Head Dia, 120 &deg MPN:02487

A countersink is an essential tool for any project involving drilling holes that will later have screws inserted into them. The primary purpose of a countersink is to provide clearance beneath the head of the screw so it can sit flush with or slightly below the surface. This prevents the top of the scrap from being visible above the surface, creating an unsightly appearance and possibly damaging surrounding materials due to sharp edges. Additionally, having a proper countersink ensures that the head of the screw is securely fastened without wobbling or appearing loose. Our high-quality 3/8'' diameter by 120 degree Countersink bit is designed with superior hardened steel for optimal performance and longevity in frequent use, delivering clean, precision-made holes. Moreover, its tapered design provides smoother insertion and reduces stress on the drill motor when driving screws, ensuring your project will last without any future complications.
