Factors to pick the Best Forstner Drill Bit Set

From a wide range of options, the right Forstner bit varies according to personal preferences. We have listed some key factors that will help you pick the appropriate Forstner drill bit set, whatever your budget or intention is:


Picking an exact size Forstner bit can let you complete the task for once. But having a set of Forstner bits with a variety of sizes will ensure greater flexibility and keep you prepared for any time and any size required.

Cutting Edge

Forstner bits come in three types of cutting edge, from knife-edge bits to those that cut through at the quickest speed. However, it puts lots of consistent strain on the drill press motor, gets overheated, and ends up dulling rapidly. Another type is a wavy edge which comes with serrations to disperse the heat and preserve the sharpness for a longer time. But this type of forstner cuts through slowly and may leave a rougher finish. Conversely, a saw-tooth edge Forstner bit can handle higher speeds but isn’t suitable for plywood, especially for cutting at an angle.


Most of the Forstner bits are made of high-speed steel to hold the cutting edges and offer repeated operation. Apart from these, you can pick a Forstner bit made of carbide-tip that is also tougher enough and retains cutting power. But choosing the Forstner bit set of high quality will cost more than its lower counterparts.

Number of pieces

Whether you are a professional or a seasonal DIYer, having a Forstner bit set with more size variations will help tackle any wood drilling task while maintaining quality and versatility. Though you can choose from 3 to 16 pieces of Forstner bit set, don’t compromise the quality for the number of bits due to the limited budget.

In general, the Forstner bit comes with two types of the shank, including a hex-shaped shank and a round shank. The first type is most suitable for impact drivers and ease of removal. Conversely, round shanks are compatible with drill presses, and even power drills, thanks to their adjustable chucks.


The price of the Forstner bit set is directly related to its quality and the number of pieces included. So set the budget based on the drilling task at hand and whether it is heavy-duty or light duty.

How to Use a Forstner Drill Bit with a Drill Press

Drilling through holes using a drill press ensures exceptional precision. However, there is a limit to the versatility of this method.

Place Work Piece and Backing

Start with placing sacrificial wood on the work surface of the drill press. Clamp the wood piece down so it doesn’t move due to the pressure during drilling through it. You can place another piece of wood over the sacrificial wood for practice if you don’t have previous experience. Doing so will also help you prevent blowouts that may occur due to drilling all the way through the workpiece.

Attach the Bit and adjust it

Still, you can insert your Forstner bit into the drill press if there is a previous work piece and backing placed. Now adjust the height of both the drill press and the Forstner bit to drill through at the desired depth properly. You can also adjust the depth whenever you need to, especially for different depths of holes.

Align and Begin Drilling

After attaching and securing the bit, mark on the work piece using a pencil to drill through at the exact point. Then align the mark with the drill bit center, lowering the arm on the drill press to keep the motor off. Now slowly press the bit against the wood piece to control the resistance feeling that is usually caused using the Forstner bit. Once you start creating the hole, you can apply more pressure through the arm of the drill press to increase the speed.

Slow Down, and Finish

Once you almost drilled to the desired depth, slow down the drill’s speed. In particular, you should set the drill press speed at the lowest setting once you reach the target depth. Doing so will keeps the bit spinning while you will pull out the bit and leave a hole with a cleaner vertical edge. Conversely, if you need to create a full hole, you can carry on from this stage, but clear out the excessive sawdust to prevent build-up overheating.

How to Sharpen Forstner Drill Bits

Tools require:

  • Round chain saw sharpening tool
  • Triangular file
  • Vise

The method

Firstly, clamp your dull Forstner bit using a vice and a set of V-blocks. Use the round file to work on the rim and make sure you are working on the dull surface. Usually, the edge of the Forstner gets dull, so you have to sharpen the face with a triangular file at an upward-facing angle.

Sharpen the edge of the bit across its whole length at both sides. You can do it in a better way by counting a number of strokes and repeating it opposite the site. Then place the bit on even surface to sharpen the chipper that is placed at the center of the bit with a triangular file. Then sharpen the Forstner bit following an upward motion. Once you have done it, check the Forstner bit to test its performance.

Pro note: usually larger Forstner bit includes cutting edges on the rims, unlike the common drill bit. If you need to sharpen such a Forstner bit, apply the same process. Start with sharpening on the Forstner bit rim using a round file and focus on the individual teeth.

Use a pointed guide to enlarge the hole

Similarly, spade bits and Forstner bits have a little sharp point in the middle that serves as a pivot point. If you want to extend the existing hole in the wood, the bit can be quiet. So you have to pay extra attention to centering the hole and aligning the bit over an existing hole with the sharp point. After that, clamp, the bit firmly and drill the new hole. even you can secure the workpiece on a backer board to reduce the risk of tear while applying a larger Forstner bit.

Advantages of Forstner Drill Bits

Except for providing greater control in woodworking, the Forstner bit brings lots of benefits over other types of bits. Some of the key advantages are:

More efficiency and accuracy

Using the Forstner bit, you can have precise flat bottom holes. Considering the smoothness of the hole, the Forstner bit offers tremendous quality compared to the twist bit. Even you can have clean holes through thicker wood using the Forstner bit.

Minimal Tear Out

Forstner bits usually produce less tear compared to other types of bits. Drilling through wood can remove fibers due to their cutting action, which leaves uneven spots. Thus, it needs further repair. Conversely, the Forstner bit acts soft on wood and ensure neat finish.

No Slippage

Whether it is a starter hole or a larger diameter, Forstner bits maintain great quality right from the initial stage. While using twist bits brings the concern of moving away from the target, the Forstner bit can effectively prevent slippage. Coming with the center spur, the Forstner bit enters into the wood efficiently.

Suitable for creating larger hole

The Forstner bit is suitable for drilling deeper and larger holes. While twist bits come only in a few sizes, Forstner bits are available in a wide range of diameters and lengths to choose from.

budget friendly

Though some of the lengthy Forstner bits are expensive, the common sizes are reasonably priced. Within your budget, you can easily pick up a Forstner bit set of considerable quality.
