1 1/2" Radius Horizontal Crown 1/2" Shank Router Bit

I use this to make cuts on synthetic decking boards - this allows for rounded and irregular shapes to be cut cleanly with no large gaps. It took a few test passes to find the right speed and feed rate (fast, but not so fast as to melt the plastic). The end result is a very professional product that customers have raved about.

This bit fits into pretty much any router, and does a nice job of slicing an 1/8" path through wood, aluminum, plastic, vinyl, laminates, etc.

This bit is a down-cut bit; which means it pushes the cut-away chips into the workpiece. The main benifit of this type of cutter is that it is much less likely to chip a workpiece that has a thin and/or fragile face, such as plywood or lamitated surfaces. However, it only has two flutes; so it cuts quickly and easily -- but not as cleanly or smoothly as finer ones.

This two-flute, down-cut configuration will cause less chipping than a similar up-cut bit; but may leave a rougher looking groove than a finer one.

If you need a clean cut; your best bet is to cut in multiple passes, with the final one being very shallow.

Delivery was earlier than offered, well packaged, now I will test its performance.
