= General Drilling = 1. Use a drill gage to determine drill size. 2. Be sure drill is sharp and ground properly. 3. Be sure the material is clamped firmly. 4. Feed drill into material at a constant rate. 5. When drilling round stock, use a "V" block vise. 6. Place work on a block of wood to prevent damage to the table.
 * B. Safe Operational Procedures: **

1. Using a combination square, draw two lines perpendicular to each other with their intersection being the center of the hole to be drilled. 2. Select proper drill speed. · Use 1250 rpm for most wood drilling up to 3/4" diameter.  · Larger bits should run at a slower speed.   · Expansive bits will burn if run much over 600 rpm.
 * Wood Drilling **

1. Use a scribe or scratch awl to mark point for punch mark. 2. Center punch a mark large enough to receive the point of the drill 3. Select the exact size of drill. 4. Use a pilot hole for holes larger than 1/2". 5. Select the proper drill speed for drill size. 6. Use cutting oil when drilling into steel. 7. When drilling holes to be tapped, be sure to use the exact drill for the size tap selected. The hole should be approximately 1/16" smaller than the tap size.
 * Metal Drilling **

1. Clamp the material to be drilled securely to the table. 2. Place the long end of the piece being drilled to the left so it will hit the post and not the operator should the material slip and start rotating. 3. Be sure the chuck is tight on the drill and that the drill and chuck match. 4. Always remove the chuck wrench from the chuck immediately after using it. 5. Do not feed the drill faster than it can easily cut. 6. Keep long hair tied back or covered to keep it from getting wrapped around the chuck. 7. Slow drill feed when it is breaking through the material to finish a hole. 8. Clamp sheet metal between two blocks of wood and drill through wood and metal.
