Spot face milling is a process where a larger well is drilled into a material after the initial hole to allow a nail or screw to sit flush with the surface. This technique is used in woodworking and machinery projects and can be done using specialized tools. Counterboring can be forward or reverse, and there are specialized tools available for specific drilling needs.
Spot face milling is a mechanical drilling or milling process. After the initial hole is drilled, a larger well, or recess, is drilled into the material. The screw or nail head fits into this well. This allows the nail or screw to sit flush with the surface of the object being drilled. This term is also spelled as face and face flat by machinists and component manufacturers.
This technique can be used on a variety of machine and woodworking projects to ensure a smooth, professional finish. Furniture makers often use it to hide nails and screws. Machines with working parts also use face milling. This can help ensure that nail, screw, or bolt heads don’t get in the way of moving parts.
Both professional and do-it-yourself carpenters and machinists can use spot coating. When working with wood, this process is also known as counter sinking or double sinking, a nut or screw. Amateur carpenters generally use different sized drill bits for countersinking. Professionals often use a special one-piece drill bit to do this.
Stitch facing, also known as counterboring, can be forward or reverse. In forward countersink, the well is drilled on the top surface of the object to be drilled. Backsink involves drilling a well into the underside of the object being drilled.
The term face milling is sometimes used to identify a specific type of spot face. Some machinists use the term to refer to working with an object that is not flat or has been cast in metal. For example, when you drill into an object with an angled or round surface, this is called pointing.
Special tools, called spotters, can be purchased to make this process easier for a machinist. These tools are usually referred to as facet cutters. Generally, these are metal rotary drill bits with cutting edges that match the size of the hole being drilled or routed.
The counterbore is attached to a drill press. It rotates in the drill, while the object to be drilled remains stationary. When the drilling process is complete, a smooth hole with the well on the top or bottom of the object is ready for a nut, bolt or screw to be inserted into.
Counterbore tools are available from several manufacturers for specific drilling needs. Tools can be specialized for forward or reverse flaring. There are also combination tools available that do both types of work.
