Cabinetry Handles
Firstly, you need to decide what location these are going to to be positioned. For traditional handles, a horizontal or vertical position are preferred depending on your design.
Once you have established this, you can use your sliding combination square to pencil mark the central position of your handle. Then pick the location of the door and measure to the same point on the door, either the top or side face and set your sliding combination square to this measurement and mark the end of the handle.
Now flip your handle upside down and pencil mark the pre-drilling positions for the screws of the handle. Using the 5mm drill bit, pre-drill you handle holes and using the screws provided fix the handle the cabinet face.
Measurements may change for each cabinet depending on drawer and door faces and your preference on handle sizes if these are different for each cabinet.
