I. Countersinking

Using a drill press to do countersinking ensures superior accuracy and repeatability. The job entails the beveling or tapering of the end of a hole using a conical cutter. The hole has to be slightly countersunk so pins can be driven effortlessly into a workpiece. It will also allow you to form recesses into which to place flathead screws. The drill press ensures that you can run the countersink at approximately half the speed for the same drill size. You want the feed to be light but not overly so as to cause chatter. The depth stop of the power tool ensures that the recess will enable the flush positioning of the flathead screw to the surface.

 

II. Spot Facing

Basically the same as counter boring, spot facing requires the use of a drill press that will ensure secure mounting of the stock while eliminating the backlash from the drill press spindle. When an ordinary hand drill is used and you have to work with rough castings or uneven and rough or curved surfaces not at right angles with your cutting tool, chances are you will end up with a broken tool. The tiltable work surface of the drill press lets you start the spot facing and avoid too much feed, preventing damage to the stock and avoiding wastage of material.

 

III. Tapping

Sometimes, you will need to cut a thread into a drilled hole. Thanks to the special ability of a drill press, you are even able to select and drill the proper tap drill size and then use the tool chuck to secure the tap in place and align it while turning by hand. Although you can’t really carry out power tapping, you can still use it to do hand tapping by switching the unit off then connecting the tap directly into the machine’s geared drill chuck and turning the drill chuck with your hand. You will of course have to apply light pressure on the tap using the hand feed lever, a technique that also works nicely when using small drill presses that allow hand-feed.

 

IV. Reaming

The drill press also enables you to ream a drilled hole. Although nearly impossible, this job entails that a hole be drilled to an exact standard diameter, and the drill press provides the level of accuracy necessary for the task. Using the drill press, you must first drill a slightly undersized hole and then proceed to ream that hole to size. The slight chamfer characteristic of the drill press tip will aid in the starting and alignment of the ream. The machine ensures smooth and sharp cutting edges while the smooth work surface lets you work consistently. You get just enough feed pressure thanks to the pulley system that controls spindle turn so you won’t end up with a damaged workpiece.

V. Hole boring

Accurate boring requires that you use a rigid and sturdy machine that can deliver sufficient power feed. This job is not recommended to be carried out with a manual drilling machine such as a hand drill, since hand feed will not be smooth enough and can even be dangerous. The tool bit might even catch the stock and throw it back at you. The drill press lets you secure your workpiece on the work surface using a clamp or vise. The bit is directly above the workpiece so entry is precise. You simply set to the appropriate spindle speed that matches the material as well as the diameter of the bit. Use slower spindle speeds for large diameter bits and hard material. On the other hand, use faster spindle speeds for soft material along with small diameter bits.
