What is the difference between Countersink & Counterbore ?
Countersink & Counterbore ?
A countersink is a cone shaped hole cut into the laminate. It is typically used to allow the tapered head of a screw to sit flush with the top of the laminate. By comparison, a counterbore makes a flat-bottomed hole and its sides are drilled straight down. This is usually used to fit a hex-headed cap or screw
Countersink
A countersink is a cone shaped hole cut into the laminate. It is typically used to allow the tapered head of a screw to sit flush with the top of the laminate. By comparison,
To accurately drill your countersunk holes, we will need below info :
- Angle of the drill
- Major Diameter (finished Dim.)
- Depth the countersink
- Which side of the board is the sink on (Top or Bottom)?
- The finished diameter of the shaft of the hole
- Plated or non-plated (Sink / shaft ) ?
Counterbore
a counterbore makes a flat-bottomed hole and its sides are drilled straight down. This is usually used to fit a hex-headed cap or screw.
A counterbored hole is typically used when a fastener such as a bolt or cap head screw is required to sit flush with or below the level of a surface.
To fabricate your counterbored holes, we would need to know the following information.
- Major Diameter (finished diameter of the hole at the surface)
- Depth the countersink is to be drilled
- Which side of the board is the sink on? Top or Bottom?
- The finished diameter of the shaft of the hole
- Is the bore and shaft to be plated or non-plated?
Because the sides of the hole are always parallel, there is no need to specify an angle.
