Counterbore HSS For Screw Size #4

A counterbore is a critical piece when it comes to precision machining where threaded fasteners require an interface with other components that don't require as much strength but demand smooth finishes. High Speed Steel counterbores provide superior performance compared to carbide, lasting longer under tougher conditions while still being cost-effective options when working with metal materials including aluminum, stainless steel and iron castings - making them versatile enough for most workshops' diverse needs. With sizes designed for size #4 screws, they save time by reducing pilot-hole drilling efforts after deburring edges; simplifying assembly processes while increasing component quality standards demanded today in multiple industries where reliability holds utmost importance.

High-speed steel counterbores are the most common choice for creating a flat-bottomed cavity at the top of the hole so that a bolt, nut, or other part is hidden beneath or sits flush with the top of the hole when installed into it. High-speed steel is less brittle than cobalt and can better withstand vibration and chattering. Sometimes known as solid pilot counterbores, these counterbores have a built-in pilot that cannot be removed and which keeps the counterbore centered in the hole to ensure a level seat.
