What is a Downcut Bit?
A down cut bit is a router little bit developed to press the chips downward right into the reducing groove instead of up as an up reduced layout does. This results in a cleaner leading edge on a dado or groove while likewise reducing the propensity to lift slim job items throughout CNC routing.

The most usual usage for a down cut spiral bit is for making dados and also shallow grooves, particularly those where the edges will certainly show up when the job is completed. Nevertheless, this does call for a somewhat slower feed price to give the chips time to clean out of the cut.

If you are confused regarding which bit to use, the most convenient method to tell is to have a look at what direction the grooves are moving around on the right side of the bit. If the flutes twist right towards the idea as they walk around on the best side, then it is an up cut bit as well as will leave a tidy top surface while leaving a harsh lower side (the part that the bit gets in).
Up cut bits are typically faster reducing and can be used for mortise as well as tenons or various other grooving, slotting or routing deep blind holes where an effective chip leaving design is required. They can also be utilized to make fine surface job such as veneers, laminates, inlays as well as repair services.
One more method to inform is to hold the little bit in your hand and also transform it slowly. As you do so, see just how the light assesses the tip of the bit as well as if it goes upwards as you turn the bit after that it is an up cut.
A down cut little bit has sharp grooves that press the chips downward into the cutting groove instead than upwards as an up reduced design does. This minimizes the tendency to lift slim work items throughout CNC router directing and also assists with tearing or cracking on your work item.

While this does cause a cleaner top side on a groove or dados, it additionally lowers the effectiveness of the bit in eliminating chips from the material also. This is a trouble when cutting deep openings or dados where the chips can get caught in the cut and also trigger it to get too hot or break.

Due to this absence of a solid chip ejection capacity, a down reduced layout is not suitable for directing with thicker product such as plywood and also melamine. It will call for a slower feed rate to enable the chips to remove of the cut before they begin to build up.
