All About The Pilot Hole Drill Bit

By Ann Stone


In the woodworking enterprise, precision and quality work are very much important. This is why precision oriented instruments are needed to bring about the desired outcomes. One such instrument that is indeed very much indispensable is the pilot hole drill bit.

A pilot cavity is driven into the wood or just about any mooted about material for practical reasons. In fact, it helps in more ways than one. The most preponderant of these reasons, however, is that it precludes the possibility of the screw from splitting the woods core. It also ensures a precise and easier installation. Directional markings aside, the screw may follow the holes angle and path, allowing it be installed straight and accurately to boot.

Without this pilot dent, many kinds of problems may ensue. For example, instead of a screw being a necessary means to an end, it will instead act like some sort of wedge which compromises the outputs structural integrity. That is because outward pressure is generated, that which will ultimately result to the splitting or damage of the material.

That said, the resulting hole can be the full extent of how far you actually mean it to go. Also, it could merely be a portion of that depth. There are many kinds of drill that cater to different kinds of applications. For example, you may use a standard twist, or else a stiff center. The latter is more precise while the former is recommendable for certain kinds of material.

These pilot dents do not only function as reference points. Rather, they have the all important function of preventing the material from cracking and splitting. The principle of the matter is that as you drive the nuts and bolts into the wood, you are also displacing it, and in its turn, there is more pressure from the spiral on the surrounding wood, which may result to immediate or gradual damage.

Anyway, you may use a conversion or correspondence char to toggle together hole diameter with bolt sizes. These references are widely available online. The general thing to keep in mind, though, is to stick to the smaller side when it comes to your choices of bits. After all, when you think about it, a smaller hole can be made larger, but the reverse is no longer true and applicable.

Of course, we need not have plunged into such a long winding discourse on the importance of pilot dents. After all, it is also a very much practical method since it makes it loads easier to drive in the screw. Screwdrivers by themselves would actuate to quite a lot of unnecessary elbow grease and an all out power drill might just be too much.

The important caveats to take to consideration is that the pilot cavities should be smaller, and just slightly at that, than the bolt. That has the important provision of keeping the material from being damaged in any way, especially cracks and splits. In this enterprise, estimates are very important. Even a slight mishap can translate to serious deficiencies or structural problems in whatever fixture you are creating.

There are other important caveats to keep in mind. One such thing is to make sure to choose the appropriate size of bits to go with your screw or some such fastener. It is also important to mark locations and practice all the arm works and mechanisms that make for a successful drilling. After all the elbow grease, however, you may be able to remark on the excellence of your DIY handiwork.
