Types of 1/2 Inch Router Bits
Straight Router Bits
Straight router bits are the most common type of router bit. They feature a simple cylindrical cutting edge and are ideal for cutting grooves, dados, and mortising applications. These bits are available in various diameters and lengths, making them versatile for different woodworking projects. Brands like Whiteside Machine Company and Woodline USA offer high-quality straight bits that ensure smooth cuts and durability.
Spiral Router Bits
Spiral router bits are designed for clean cuts and are commonly used for inlay work and more detailed applications. They come in both up-cut and down-cut designs, allowing for versatility depending on the material being used. Up-cut bits pull chips upwards, while down-cut bits push chips down, providing a cleaner finish on the top side. Brands like Woodpeck offer a range of solid carbide spiral bits known for their longevity and precision.
Flush Trim Router Bits
Flush trim bits are used primarily for trimming laminate and veneer edges flush with the substrate. They typically feature a bearing on the top that rides against the edge of the workpiece, ensuring a precise cut. This type of bit is indispensable when working with edge banding or laminates, making it a favorite among woodworkers.
Round Over Router Bits
Round over bits are used to create a rounded edge on wood projects. They are perfect for furniture making, cabinetry, and decorative edges. By selecting a round over bit with the desired radius, woodworkers can achieve a professional finish that enhances the aesthetic appeal of their projects.
Cove Router Bits
Cove bits are used to create concave profiles on the edges of wood pieces. This type of bit is excellent for decorative applications and can add a unique touch to furniture and cabinetry. Cove bits are available in various radii to suit different design preferences.
Dado Router Bits
Dado bits are specifically designed for cutting dado joints, which are essential for creating strong joints in cabinetry and shelving. These bits can have multiple blades, allowing users to cut various widths of dadoes efficiently. They are often used in conjunction with a router table for precision.
Rebate Router Bits
Rebate bits (or rabbet bits) are used to create a recess on the edge of a workpiece. This is particularly useful for fitting joints and making picture frames. The clean edges produced by rebate bits ensure a snug fit between pieces, enhancing the overall quality of the project.

Tips for Using 1/2 Inch Router Bits
When using 1/2 inch router bits, consider the following tips for optimal results:
- Choose the Right Bit: Identify the specific application and select the appropriate bit. Each type has unique features that impact the cut quality.
- Use Proper Speed Settings: Adjust the router speed according to the bit type and material. Most 1/2 inch bits perform well at RPMs between 16,000 and 24,000.
- Maintain Sharpness: Regularly check and sharpen your router bits to maintain cutting efficiency. Dull bits can lead to poor finishes and increased wear on your router.
- Feed Rate Control: Use a consistent feed rate while cutting. Forcing the bit can cause burning, chipping, or damaging the bit.
- Multiple Passes: For deeper cuts, make multiple shallow passes rather than attempting to cut the entire depth in one go. This reduces the risk of breaking the bit or damaging the material.
- Use the Right Feed Direction: Always cut against the rotation of the bit. This ensures better control and cleaner cuts.
- Safety First: Always wear appropriate safety gear, including eye protection and dust masks. Ensure the router is securely fastened and use push blocks where necessary.
