Why Choose Spiral Router Bits Instead of Straight Bits? Spiral router bits combine a shearing action with an augering action for chip clearance. This dual action not only produces a clean and accurate cut but also efficiently clears chips from the cut area, enhancing the overall cutting experience. What is Compression (Up-Cut & Down-Cut) Bits? Features: Compression bits combine the features of both up-cut and down-cut bits. The top part of the bit is designed to be down-cut, improving the top edge finish, while the bottom part is up-cut, enhancing the finish on the bottom side of the material. This up-cut down-cut action is what leaves a sharp, clean edge on both edges of your workpiece.  Applications: The preferred bit for cutting laminated materials or any situation where both sides of the material are visible and require a fine finish.  Considerations: To fully benefit from a compression bit, it's crucial to make the initial cut deeper than the length of the up-cut flut
