 ===== Operating Procedures =====
----
+  - Layout and center punch the holes you wish to drill
+  - Insert drill bit into the drill chuck, tighten with the chuck key, and remove the chuck key before continuing. Note: Do not tighten the chuck by powering on the machine and do not leave the chuck key in the chuck. These are both extremely dangerous and unsafe practices.
+  - Align the holes with the drill bit and secure the part using the vice or the drill bed clamp.
+  - Adjust the work table to the appropriate height and lock securely.
+  - Check that the tool can spin freely and that it is clear of the part.
+  - Determine the proper feed rate and speed rate for the given hole/material. Adjust the machine to this speed. There is a chart in the SOP that can be found under "Reference Documentation".
+  - Apply cutting lubricant to the part
+  - Turn the machine on
+  - Use peck drilling operations to drill the hole, remove material in 0.05 inch increments.
+  - Remove chips and swarf using a brush. Do not use a rag or your bare hands to remove chips.
+  - Apply additional cutting fluid as necessary throughout the operation
+  - Reduce pressure when breaking through to prevent damage to the tool and part. Use backing board to prevent the part from blowing out.
+  - Power down the machine when done. Do not attempt to slow the machine down by hand.
+  - Use a brush and/or rag to clean up any chips, shavings, and oil from the drill press and the surrounding areas.
+  - Return all tools to their proper location and power down the drill press. Tidy up the work area.
