SAFETY RULES & BASICS FOR PRESSES

Drill presses are designed for cutting holes into metals, plastics, and wood. Although a very commonly used piece of equipment, the rotating presents a safety risk if not used properly. Be sure to always follow good safety practices in the shop as described in General Robotics Safety Rules. Specific rules for the drill press include:

 Always secure all work in a vice or clamp. Never try to hold work in your hands while . If the drill catches, the work will be jerked out of your hands and may injure you.  Be certain that the table and drill press head are secure before cutting.  Always place a piece of scrap material under your work piece to ensure that the drill bit does not hit the table.  Be sure that the drill bit shank is secured firmly in the . Only use drill bits in the drill press.  Never leave a chuck key in the chuck socket. If the power is turned on, the key will be thrown out of the machine and may injure someone.  Adjust the drill press to the correct speed for the material and hole size being cut. Refer to the chart on the material. A drill too fast may break and cause injury. Larger holes require slower speeds, smaller holes require faster speeds.  Operate the feed handle slowly such that the drill cuts evenly and smoothly into the work piece. Be sure to stop feeding the bit once it has passed through the work piece.  Never touch the rotating drill or chuck as serious injury may result.  When drilling a deep hole, remove the drill bit from the work several times to clear out chips.  It is wise to always set the depth guide before cutting to ensure the bit will not hit the table.  Always select the proper drill bit and be sure it is sharp. A dull bit can heat up and break causing damage and/or injury.  When adjusting the speed of the drill press, be sure the machine is turned off and unplugged. Rotate the wheels slowly to move the belts up and down. Always move the belt down to a smaller wheel before moving the other side to the larger wheel to prevent belt stretch.  Never try to stop a rotating piece of work that is caught in the drill by grabbing it. Remain calm and shut off the machine.  Ease the pressure on the feed handle as the drill breaks through the under-side of the work piece. This will keep the drill from breaking or the work from being jerked out of the vice.  After a hole is complete, always back the drill bit out of the work piece before shutting off the machine.  Always use a brush to remove chips or shavings from the table and keep the floor area around the machine clean. Never remove shavings with your hand or a rag.  When finished with the drill press, ensure that the chuck has stopped rotating, remove your drill bit and place back in the proper container, and clean the machine before leaving.

I have read and understand these rules. I realize I must be tested and checked-out on the drill press operation and safety by a mentor before I am allowed to use it.
