Alternative Router Bit Solutions for Aluminum and Plastics

If your work frequently switches between plastics and aluminum, consider exploring an alternative solution such as the Upcut Spiral Router Bit for Aluminum or even a Router Bit for Soft Plastic and Hard Plastic. Each variant is engineered to supply clean results in specific materials and provide the adaptability that fast-paced shops require. Efficiency and predictable results are fundamental, no matter the job’s material complexity.

Best Practices for Maximizing Tool Life and Finish

Match spindle speed and feed rates to the exact material for optimal pocketing results. Always secure your workpiece properly to safeguard both operator and finished work quality. For plastics, using compressed air or a mist coolant helps avoid heat, preventing unwanted melting or surface warping.

While machining aluminum, lower the feed rate and keep the spindle steady for smooth performance. This method minimizes burrs and delivers superior surface quality. Make a habit of cleaning any accumulated chips and dust after each job to maintain sharpness and avoid performance loss. Regular inspection extends tool accuracy and increases its lifespan.

Before each operation, inspect your Onsrud 66-300 Series Solid Carbide Upcut Router Bit carefully for dullness, chips, or any potential wear. Using a sharp bit is essential for perfectly flat, blemish-free pocket floors. As soon as noticeable wear emerges, replace the bit to maintain consistent results over all upcoming jobs and keep performance at its peak.
