Diamwood HSS metal drill bit sharpener
When we drill in wood, metal or plastic, our drill bits tend to lose their sharpness over time, so it is recommended to purchase a drill bit sharpener, since this way you will be able to sharpen them more easily and you will have a greater savings by reusing your drill bits.
As for the DW-250254000 model, it is an HSS metal drill bit sharpener whose purpose is to restore the drilling capacity caused by wear. In addition, another aspect that stands out in this product is that it can also give the tip stability. That is, so that the drill does not move from position when drilling.
In the following section you will find a guide to buying the best drill bit, where we will detail the most important characteristics that you must take into account so that you can select a good and economical one considering the aspects of resistance, type of material to work with and diameter.
The first characteristic that we recommend evaluating in this comparison of drill bits is the type, since there are some that have a special purpose. That is, to use them on wood, metal, glass, ceramics, plastics and other structures of different degrees of hardness.
If you frequently work with metals, you may have heard that these bits are intended only for the use of this material, since they have a higher degree of hardness than the others given the conditions that metal is much more resistant than polymers and other structures..
As for wood drill bits, they can come in a helical shape, as well as metal ones, as well as some that have a circular design at their tip, which will allow larger cylindrical holes to be made. These are commonly called Forstner-type bits, since they are named after the last name of the person who invented them, Benjamin Forstner.
The ideal drill bits for drilling glass, glass, ceramics, porcelain, tiles, and tiles, for the most part, have a similarity to those of wood, but the tips are sharp. Additionally, some models integrate small diamond pieces, which help make the cutting process as delicate and efficient as possible with little probability of damaging the structure.
On the other hand, you will also find the so-called SDS bits, which have the function of being used in hammer drills, since their resistance is greater than those of the conventional type, so they are ideal for intense work.
size and diameter
As for the sizes and diameter of the drill bits, there are endless ones on the market, which allows you to drill and be able to get the desired hole or one that is quite close.
Some models of drill bits have measurements represented in fractions and others in millimeters, these being the ones that will determine the result of the drilling. That is to say, a drill bit with a diameter of 1mm will be the reference to the hole itself, so the greater the measurements in centimeters, the hole will also be.
On the other hand, the sizes of the bits are also variable, which will allow you to obtain holes according to the height of the bit. However, keep in mind that placing the bit in the drill will reduce its size to fit, so don’t rely on the hole being the length of the bit, but rather use it as a rough reference..
Likewise, it should be noted that there are special drill bits that reduce the replacement time, these are the stepped type, which have a conical head, but as its name indicates, it has steps. Each one of them represents a measure and by not having to change between bits, the working time will be much less, being very practical tools for those users who need to make various sizes of holes in wood or metal.
Before verifying how much a drill bit costs, you should consider the manufacturing materials, since these are the ones that will determine the durability, as well as the protection against rust or corrosion, since it is one of the main causes of wear and weakness.
The most recommended materials in drill bits are metals that have stainless properties, with stainless steel, tungsten, cobalt and titanium being the most used to make drill bits, since they have high levels of tolerance to rust and corrosion, as well as as well as the degrees of hardness of these are higher than other metals.
Additionally, if the bit is nickel treated, the tolerance towards rust and corrosion will be even higher.
On the other hand, when a piece presents the initials HSS or indicates that it is ground, it means that the processing materials have high speed steel or it is mixed with other components, which increases the properties of the drill in a significant way.
Frequently asked questions
Q1: How to use a drill bits?
First, you must identify what material you are going to work with, since there are special bits for each type and, if they are not used correctly, they can break in the process and even damage what you are drilling.
After selecting the drill bit (for wood, concrete or metal) you have to consider that you must work the drill at a specific speed so that the drill bit does not suffer damage. In other words, use low RPMs for hard metals and higher RPMs for softer metals, wood, plastic, and other brittle structures.
Additionally, so that you can prolong the useful life of your drill bits, we recommend that, after use, you perform a general cleaning of them with a dry cloth to remove particles and liquids so that you can then apply a metal cleaner. Verify that it does not have bleach or chlorine so as not to damage the protective layer.
Q2: How to sharpen drill bits?
You’ll need a grinder with a rough pumice wheel or disc, gloves, and goggles to protect your eyes. Now, you will have to fix the grinder on a surface so that it does not move while you are using it.
First, remove the damaged part of the bit by shaving horizontally and evenly. Then, you will have to make the bit have a 30° drop on both sides, since this will allow it to rotate evenly. To do this, place it in a diagonal position and immediately make the degrees of fall by making a small movement of the bit upwards. Do the same with the other face and check that both are as identical as possible, but respecting the axis, since it must be perpendicular to the diameter.
Q3: How are steel drill bits made?
First, this begins as a metal rod, which is then placed in a machine that is responsible for making the cone-shaped tip and, later, passes to another that will be responsible for making the shape of spiral grooves. At the end of a certain series of bits, they are all coated with titanium to give them protection, durability and greater resistance.
Q4: Why are drill bit measurements expressed in fractions?
These are expressed in fractions in order to approximate the result to be drilled for each drill. That is, the fractions are divided to obtain a decimal number, which is equal to the exact drilling diameter of the drill, allowing the selection of one that is as close as possible to the hole you want to obtain.
Q5: How to differentiate the drill bits?
Drill bits that are for metals have 2 spiral-shaped flutes and their tip is triangular. On the other hand, those that are for wood have 3 sharp points, where one of them, specifically the one in the middle, works as a drilling guide. And, those that are used for concrete have a head at the tip that provides robustness and improves the ability to drill from stones to bricks.
