Description

See more product details The big difference between straight and spiral bits is the angle of their cutting edges Straight bits chop wood straight on, while spiral bits cut at a shear angle. The spiral flutes have a lot of advantages: better chip evacuation, less heat buildup, and cleaner edges. Down-cut and up-cut are differing in cutting direction and how wood chips are evacuated. The down cut bit leaves very clean top edges, it is great for cutting shallow dados, rabbets, and visible slots. When cutting dados or grooves with a down cut bit, be sure to slow the feed rate to allow more time for chip removal. The up cut is better at evacuating chips, it is perfect for grooving, routing deep holes, slotting, and mortise. it performs faster cutting while pulling the chips up.
