The recommended chip load & feed rate data provided below is a recommended starting point and may not accommodate all circumstances.

A router tool has a flat base and a rotating blade that is driven by a motor. They are considered an extremely versatile power tool and can either be handheld or attached to a router table. Our UK router bits are imperative to achieving your desired design in whatever material you are working with. Always start out at the lower feed rate and work your way up from there until optimal cutting conditions and speed is acquired

We would recommend running at 18,000 RPM for most single, 2 flute and 3 flutes up OR down cut router bits That is true for the other way around, too. You can hardly tell a difference with the naked eye, and the bits will fit in "just fine" either way. A slower feed rate is required with down cut bits as this allows more time to evacuate chips and for them to be cut into smaller pieces that fall from the slot. This does mean that you need to be careful the bit does not overheat and consequently break. This can be due to the build-up of chips combined with a deep cut.

An up cut bit is typically used to remove chips from the hole that it is cutting. Deep grooves need to be fashioned out using continual light cuts. Up cut bits are ideal for this as the upward direction of the flutes inhibits the build-up of debris which can either break or bind the bit. As the flute removes chips it can simultaneously fray the wood fibres, causing damage. You must be mindful of this when using up cut bits and be careful to avoid implementing damage to your project. As a rough rule of thumb we usually advise the depth of cut as 1 x cutting diameter. However, in some circumstances a smaller or larger depth of cut may be optimal. A down cut router bit is effective in forming a crisp edge around the hole that it is cutting. However, it is less effective in removing chips from the hole when compared to an up cut bit. Therefore, down cut bits are more commonly used for making shallow cuts rather than deep grooves.However, using an imperial bit in the corresponding (well, almost corresponding) metric collet is dangerous both during the operation and when using the collet with your 6mm bits as intended afterwards. I've seen people do it, too, and they so far got away without accident or even physical injury. (Which makes the whole matter worse because that "proves" that it works.)
