Best Forstner Bit Reviews

Drill bits that are usually used in woodwork projects like furniture making are known as a forstner bit.  The geometry of drill bits differ depending on the drill being used. Examples of geometry aspects that are many drills have include a spiral, point angle and lip angle. These aspects determine the use of the drills, for example a drill with a spiral rate will be used on jobs that require faster feed rates. Now, drill bits are usually used together with drill presses or hand held drills to create holes in metals, plastic and wood materials. In many occasions forstner bits are costly when compared with the normal twist bits but they have fewer desirable features.

The most important criteria for Choosing Forstner Bits

In order to be able to define the decisive points of criticism before the purchase of forstner bits, some considerations must be taken into account before the purchase decision. Ultimately, the choice of a particular model is always one of the most important issues. This also determines if the forstner bits meet your expectations and fulfills its purpose for a longer period of time.

  • The first criterion is, therefore, when, how often and for what drill forstner bits are needed. Each product must be durable and robust, especially if it is used frequently or even constantly.
  • The quality of the forstner bits is therefore, together with the other characteristics of the forstner bits, the most important point. This is the only way to decide if your choice is the right product.
  • Therefore, consider what the forstner bits should be able to do to meet your needs before looking through the whole selection of forstner bit comparison.
  • The brands, sizes and adjustments, as well as the areas of application provided, facilitate the selection.
  • You should think about it from the beginning: What size, performance and adjustments your ideal forstner drill should have. This will facilitate the selection in the next steps. Your own needs are also one of the most important criteria here and play a decisive role in finding the perfect forstner bits.

DerBlue 5Pcs Professional Forstner Drill Bit Set Woodworking Hole Saw Wood Cutter

It is always nice to have drill bits that are easily accessible and come in many shapes and sizes. The problem with most drill bits are that often they do not have a diverse amount of sizing for the job that needs to be done. Most sets do not have enough sizes or settings to do everything somebody needs to do when it comes to shop work. One of the best things about the DerBlue set is that it comes with just the right amount of bits to do whatever is necessary. They range from 15mm to 35mm in size of the bits that can be connected to them, and can fit most drills which is also a very nice thing about the DerBlue set.

There are a couple of issues with the DerBlue set. The first issue is that they do not arrive really sharp. In all probability, it will be necessary to sharpen the bits in the set before using them as they do arrive more dull than normally. Also, if you have a rotary drill or even a hand drill, it will be close to impossible to attach the DerBlue bits to them. They just do not seem to have the flexibility to perform well on a hand drill as they would on a drill press.

PORTER-CABLE PC1014 Forstner Bit Set, 14-Piece

Drill bit sets need to have variety. There is nothing more stressful than having drill bits for every size except the particular size that you need. The Porter Cable set contains drill bits of many sizes which is very nice. They come with 14 different sizes so this eliminates any questions or guesswork when it comes to choosing a drill bit.

The case that the Porter Cable comes with is very small, easy to carry, and does not take up a lot of space. This is really good for anyone who does not have a big workspace to work with. Additionally, different than some forstner drill bit sets, it is possible to place these bits into a hand drill.

Because the Porter Cable set has so much variety, there is a price to pay. And that price is that they can dull very quickly and require constant resharpening. This makes sense because the case comes with so many bits and that they are packed so tightly in the case. If you leave all the bits in the very small case it comes with in an area with extreme temperatures, it can dull the bits because they are packed so tightly together.

This can make things very disorganized for someone who works with drill bits often.

Where did the forstner bit come from?

Forster bits were invented by Benjamin Forstner and hence the name. Such bits bore flat bottomed precise holes in respect to the grain of the wood that is to be used. Such can be used to make holes overlapping other holes and even make holes from the edge of blocks of wood.

Because of their abilities to create flat bottomed holes, they can be used to add inlays by creating holes on already glued veneer. And because they require a lot of force to push them up into the material they are drilling, forstner bit are usually used in lathes or drill presses and not as portable drills. This makes them a bad choice when it comes to looking for hand held drilling tools. Another reason as to why forstner bits are often used in lathes or drill presses and not as hand-held drilling tools is that its nature at times makes it difficult to move it through the materials they are used to drill. Therefore, when using forstner bits, it is important to remember not to depend on the centers of these tools in guiding the drill deeper into the wood.

Now, a forstner bit consists of center points that lead it through the cutting. Its cylindrical cutter shears the fibers of wood at the ends of the bore, also guiding the whole bit into the material it is drilling more precisely. Majority of forstner bits also have radial edges used to plane off the materials they are used to cut at the end of a hole. Different forstner bits will have varying numbers of radial edges depending on their designs. For the reason that these drills do not have any mechanism to get off chips from the holes they drill, they have to be pulled out regularly to have the chips removed. Earlier on, forstner bits were commonly used by gunsmiths because they were very good at drilling holes with exceeding smooth sides. In addition to the above, forstner bits can be used to create holes with square bottoms hence making it possible to be used for applications that require such shapes of holes.

Again, another benefit of using forstner bits is that such are more effective in drilling larger volumes of wood in a very short time. Finally, just like the majority of other drills, you can get a forstner bit in many varieties, giving users freedom of choice.

Why Should You use Forstner Bit?

To drill in hard and soft woods

A drill bit is often used for the general drill where the concentrically of the hole and the precision of the size are not very important, woodworkers can choose from a variety of styles of drill bits: wood drill bits, mortising drill bits, drill bits shovel, drill bits for conical holes or helicoidal bits made of HSS steel or hard metal , among others.

However, for holes on wood or plastic in uncomfortable or difficult to handle places, that have a precise size and that have flat and clean backgrounds, Forstner bits are the best option.

Also drilling precise holes with clean edges and edges in hard and soft woods, plywood, MDF and laminates, these bits can improve their efficiency in holes with angled drilling, overlapping holes and holes in the edge of the material.

Note: For holes in MDF boards or abrasive boards, drilling tools with tungsten carbide plates are recommended.

Forstner drill usually have 2 flat curved edges with internal bevels, two anti-slash cuts and a centering tip

In general, they are available in diameters of up to 68 mm or more, depending on the manufacturer.

The drill bits have a configuration similar to the standard, except that the part that makes the outer diameter of the hole is notched.

These models can have diameters of approximately 10 mm to 100 mm.

Customers who have purchased a forstner bit : from the CMT brand in Tecnocorte, are more identified with the model with wavy cuts (without teeth), with a semicircle with a sharp edge in the inside curved part (wavy area).

The perception is that the wavy or scalloped contour cuts more quickly, produces less friction, reduces heat build-up and improves ejection of the chip.

 It also makes a great paper when drilling holes in angles

However to drill holes near the edge of the material is recommended to hold the piece with a jacks, clamps or screws, even more if the piece to be drilled is small or with regularities.

If you work with the right material without being too abrasive, without reheating the tool, you can sharpen between 15 to 25 times.
