Step by Step Instructions

Step 1:

Measure where you want the hole.

Step 2:

Use a punch to make an indentation so your blade will not walk out of place.

Step 3:

Apply lubricant to keep blade from over heating. Be patient because the blade can overheat, and once that happens, you won't be able to cut. Continually apply lubricant to the drill.

Step 4:

Drill out the hole. Once the hole has been created, file the sharp edges to soften them. Be careful not to cut yourself. The shavings can be sharp and scratch you or your finish, so use caution when cleaning them up.
