This tool is very essential in the workshop. In general, a modern drill model is electrically run, and is a stationary or fixed type of drill either bolted to the workbench or floor or mounted securely on a stand. It basically consists of a drill head, spindle (or quill) , table, column (or pillar) and a base. The table is usually a flat area upon which the object to be drilled is placed securely. Sometimes it is known as bench drill, pillar drill, floor drill, or pedestal drill.
The head usually has 3 sets of handles that radiate from the drill’s central hub, moving the chuck and spindle vertically when turned, and approximately parallel to the column axis. The table can also be adjusted vertically and normally moved by a pinion and rack. However, some models especially the older ones, rely on manual lifting and reclamping the table in the proper position. The table may likewise be offset from the axis of the spindle and in some other cases, perpendicularly rotated to the column.
The drill can be vertically adjusted to allow varying materials and thicknesses to fit for drilling. Some models even have tables that may be tilted to make angle drilling possible. These units are basically intended for achieving more precise drilling work.
When the orientation and location of the hole needs to be accurately controlled, a drill press becomes more preferable to a hand drill.
The Miniature Type
A mini or miniature drill model is compact and lightweight compared to other models. This tool usually sits on a workbench or a tabletop and is very handy for drilling into lighter and smaller stock. It offers variable shifting speeds for various materials and different depth settings.
This particular tool is also a portable type for use in your shop, a neighbor’s garage, or at home. It offers the control and precision of bigger drill machines for certain projects that require small parts like doll houses crafting and jewelries. The mini model is virtually an ideal size for anybody having drilling applications for small workshop, model making, for the bench jeweler, and hobby craft work.
Using the Mini Drill Press
1- First, before changing drill bits or making any setting adjustments, be sure to unplug your miniature drill. Loosen the provided chuck to change your drill bits. Tighten the chuck with the key around your chosen bit.
2- Next, loosen the knob or crank screw that tightly secures the head of your unit. To accommodate the total height of the particular stock to be drilled, just lower or raise the head accordingly. Keep in mind that maximum height setting typical for mini tabletop machines is 10 inches or less. You also have to tighten the crank at its desired height in order to secure the head.
3- For models with speed setting dial, adjust the desired drill rotation speed. Other models have knobs that stop on different speeds. Remove the cover carefully over the pulleys, then to change the speed settings, simply slip the belt onto another set of pulleys. Secure the cover before testing the different speeds.
4- To set the desired drilling depth stop, you loosen the ring or set screw on the drill’s pull handle shaft. But before adjusting the drilling depth, you must first set to zero the digital depth gauge. Then, adjust your drill bit to its desired depth as displayed by the stationary meter gauge or the digital gauge. Tighten the ring or set screw by whatever appropriate means. Your model may be provided with a crank, a hex or Phillips screw to secure the depth setting.
5- In completely drilling through stock, position the hole under your drill bit by sliding the table ledge. Leave the table ledge on any solid space if you need to drill partly through items.
6- Always put on your safety goggles before plugging in your portable mini drilling tool for actual use. Place the particular stock for drilling on the table ledge, then pull the drill’s crank handle toward you to lower the drill bit onto the stock. Position the bit on the precise spot where the hole is to be drilled. Hold the stock securely and firmly in place, then turn your mini machine on. Pull on the crank handle again to lower your spinning drill bit slowly into the stock. Drill according to your desired depth then slowly withdraw the drill bit from the stock.
There are many drill types such as bench top machines, floor standing units, magnetic machines and radial. And then there’s the mini or miniature model. They vary according to their sizes and what’s appropriate for the type or size of stocks to be drilled. For smaller drilling applications, the mini drill press is certainly the best choice. It makes your workshop complete.
