Non Wood Plastic and Phenolic Material
This section covers working with nontraditional sheet good products. To avoid chipping re-melt and difficulty cleaning out the keyhole slot in plastic or phenolic dense material try doing two passes, the first with an 8mm or 5 mm Acrylic bit (depending on the fastener used 5mm post or 8 mm post) the second pass with the Lockdowel Keyhole bit. The recommendation from King StarBoard User Guide is Larger bits and profile bits may need to be run at speeds as low as 8,000 RPMs and 100 inches per minute or slower.
