How To Choose Suitable Drill Bits

Naturally the most important factor in choosing drill bits is to find the one most suited to the type of material you are going to work on. Some, in fact, are more effective on wood, while others, more resistant, can easily pierce the steel.

Let's now see, on a case-by-case basis, which tips work best on different work surfaces. There are also other types of tips such as the adaptable tip or the Forster tip, the conical tip and the electrician tip. I got this information from toolsinsider.org, he wrote about drill bit, check it out if you are interested. The tips are supplied in different diameters and lengths and additionally extensions can be added to increase the length of the wooden tips.

Wood : It is important to know that, by working on this material, you must deactivate the percussion function and act at low speeds. The most effective wood tips are the helical ones, particularly suitable because their shape allows to easily get rid of the shavings. They can be manufactured in various materials: the most valid is steel.

Metals : Here the most used tips are the steel HSS, which are sometimes reinforced by TiN, or titanium nitrite, a compound that makes the tips golden and adds further strength. The most used shape is the spiral shape.

The use of a metal tip takes place with lubricating and cooling cutting oil, at reduced speed and at controlled constant pressure ; the metal tip must also be sharpened appropriately and frequently. Exaggerating the most expensive and hard-to-use metal tip used badly has a duration of at most some puncture.

Steel : In this case too, spiral HSS drills are preferred, which often have a flattened tip to ensure excellent grip on the surface to be drilled.

Iron : These are the "universal" tips, which can be used with good results even on other materials. They are available on the market both in chrome vanadium, suitable for working aluminum, and in steel reinforced with cobalt and the aforementioned TiN. Do not forget to lubricate and frequently cool the tip, often subjected to high pressures and temperatures.

Glass : This material, the most fragile of those listed, must be worked at low speed and low pressure, with steel spear points that allow you to carefully finish even the most demanding details.

Reinforced and non-reinforced concrete : returns the spiral and helical shape, and the shank takes the SDS shape to best support both the strong percussion and the high speed of the drill. These tips are made of very resistant steel that works without problems even at high temperatures, and are also excellent for drilling marble, bricks and stone.

It should be remembered that it is obviously inadvisable to use specific tips on a material for which they are not intended; moreover, it is essential to pay attention to the heating of these parts when used for hard and difficult to drill surfaces.

Finally, the best way to buy an efficient product is to rely on the advice of those who have already had the opportunity to try it.
