Warning: Make sure the router bit is properly fastened and tightened in the router’s collet and the bit can rotate freely without any obstructions.
Instructions: Slowly dial up the RPMs on your router to the recommended maximum. Then, dial back if needed to find the “sweet spot”. The sweet spot is the speed at which the least resonant vibration is present. If the sweet spot cannot be achieved within 5,000 RPMs of the max, check the collet for residue or other debris and start over.

1/4" steel drill bits are a great choice for cutting clean and accurate flat bottom holes. Except for the slight notch created by the center spur, the resulting holes are clean and smooth. The middle spur helps center the bit, while the outer rim helps maintain the bits position when drilling angled or overlapping holes. Steel forstner bits are sharp and rugged which will perform flawlessly over and over again.
