About Counterbores
Counterbores are specialized tools utilized in creating enlarged, flat-bottomed holes in various materials, primarily metal. They're essential when a fastener's head needs to be level with or beneath the surface of the worked material. Available in an array of sizes and shapes, these tools can accommodate diverse types of fasteners and feature different tip configurations like straight flute or spiral flute based on their intended use. Counterboring speeds differ according to the material being processed. These durable tools are typically crafted from high-speed steel (HSS) or cobalt steel for enhanced cutting performance, sometimes coated with titanium nitride (TiN) for superior wear resistance and lubricity when dealing with tougher materials such as stainless steel or aluminum. Industries ranging from automotive manufacturing and aerospace engineering to medical device production widely employ counterbores for precise hole creation necessary for mounting screws and other fasteners.
