Straight router bits are a versatile and powerful tool for any woodworking project. They can be used to create grooves, slots, and channels in wood, as well as to shape the edges of boards and create decorative profiles. However, using a router can be intimidating for beginners, and even experienced woodworkers can make mistakes that lead to poor results. In this article, we'll cover the basics of how to use straight router bits and offer tips for achieving professional-quality results.

Before You Begin: Router Safety

Before you start using a router, it's important to review basic safety precautions. Always wear eye and ear protection, as well as a dust mask to avoid inhaling wood particles. Keep your hands and fingers away from the cutting area at all times, and make sure the router is securely fastened to the work surface. Never force the bit or try to remove too much material at once. Finally, always use the proper cutting speed and feed rate for the material you are cutting.

Choosing the Right Bit

The first step in using a straight router bit is choosing the right one for the job. Straight bits come in a variety of sizes and materials, and each one is designed for specific cutting tasks. Here are some things to keep in mind when selecting a bit:

Size: Choose a bit that is appropriate for the size of the groove or channel you want to create. Larger bits are better for cutting wider grooves or channels, while smaller bits are better for more precise work.

Material: Straight bits come in a variety of materials, including high-speed steel, carbide-tipped, and solid carbide. High-speed steel bits are the most affordable option, but they may not last as long as carbide-tipped or solid carbide bits. Carbide-tipped bits are a good compromise between price and durability, while solid carbide bits are the most expensive but offer the longest lifespan.

Cutting Edge: The type of cutting edge you choose will depend on the material you are cutting and the type of cut you need to make. Standard straight bits are good for general-purpose cutting, while spiral bits are better for softer materials. Flush trim bits are ideal for trimming edges, while mortising bits are necessary for cutting mortises.

Shank Size: The shank size of a router bit is important because it needs to fit snugly in the router's collet. Most routers accept 1/4 inch or 1/2 inch shanks, so be sure to choose a bit with the appropriate shank size for your router.

Preparing Your Workpiece

Once you've chosen the right bit for your project, it's time to prepare your workpiece. Make sure the board is securely clamped to your work surface, and mark the area where you want to make your cut. If you're making a groove or channel, use a straightedge to mark the edges of the cut.

Setting Up Your Router

Before you start cutting, you'll need to set up your router. First, attach the appropriate router bit to the collet and tighten it securely. Next, adjust the height of the bit so that it is just above the surface of the workpiece. You can do this by adjusting the depth stop or by using a depth gauge.

If you're making a groove or channel, you'll also need to set up a fence or guide to keep the router on track. A fence is a straightedge that is attached to the router base and runs parallel to the cutting edge of the bit. A guide is a template that is attached to the workpiece and guides the router along a specific path.

Making the Cut

With your router set up and your workpiece prepared, it's time to start cutting. Here are the basic steps to follow:

Turn on the router and wait for it to reach full speed before you begin cutting.

Move the router slowly and steadily along the edge of the workpiece, keeping the bit in contact with the wood at all times. If you're using a fence or guide, make sure the router stays in contact with the guide throughout the cut.

If you're making a groove or channel, make multiple passes to gradually deepen the cut. Take care not to remove too much material at once, as this can cause the bit to overheat and become dull.

Once you've made the cut, turn off the router and wait for the bit to stop spinning before removing it from the collet.

Sand the edges of the cut with fine-grit sandpaper to smooth out any rough spots.

Tips for Success

Using a straight router bit can be challenging, especially if you're new to woodworking. Here are some tips to help you achieve professional-quality results:

  • Practice on scrap wood before starting your project. This will give you a chance to get comfortable with the router and experiment with different techniques.
  • Take small bites. It's better to make multiple passes than to try to remove too much material at once. This will help prevent the bit from overheating and becoming dull.
  • Use a guide or fence to keep the router on track. This will help you make straight, consistent cuts.
  • Keep the router moving at a steady pace. If you move too slowly, you risk burning the wood. If you move too quickly, you may not remove enough material.
  • Don't forget to sand the edges of the cut. This will help smooth out any rough spots and give your workpiece a professional finish.
  • Clean and maintain your router and bits regularly. This will help prolong the life of your tools and ensure they're always in good working order.


Using a straight router bit(konetool) can be a great way to add detail and precision to your woodworking projects. By following basic safety precautions, choosing the right bit for the job, and practicing good technique, you can achieve professional-quality results. Remember to take your time, be patient, and always be willing to learn and experiment. With a little practice and persistence, you'll be creating beautiful, custom pieces in no time!
