    Default Corian

    We have a large art installation rapidly approaching for Bloomberg in NYC where we will be using corian as our main material. We will be using our PRS Alpha to not only cut the corian down from stock size, but also drilling. I have been told to use carbide bits for this material. I was hoping receive some feedback from those with experience on bits, how well I can expect the machine to perform cutting this material, as well as feed speeds etc. I was thinking a 1/4" flat end for profile cuts and I need the drill holes to be 1/8" dia.

    Any feedback would be helpful!

    Thanks

    Corian cuts like butter with sharp bits. I just use the same bits as I do for cutting wood and I use the same speed as softwood. I don't have my settings here they are in the shop and I won't be back for a couple of days

    it cuts like butter. Not sure what feeds and speeds to recommend for a prs alpha, but on my old prt I use about the same settings as I use for a hardwood like walnut.

    Onsrud straight single or 2 flute "O" bit is made for that stuff and Centurian also has a great straight O bit. Also OK with downcutter of same geometry otherwise.
    Always ramp in. I used 1/4" D mostly. 3 passes to go through 1/2" Corian (or other solid surface") with the last pass just being a skin cut. Spin slow-12-15K and move slow (1.5-3ips) exact numbers may vary depending on the final size and shape of the parts you are cutting.
    The High Polyester blends are more brittle than the all acrylics. Your Alpha and Spindle will make your cutting go very smooth but don't try to rush it. Your final exact numbers will be determined by your ears, as per usual.
    For drilling, if at all possible, I would use an actual drill bit made for plastic (or with the back spur filed at the bottom) and use peck strategy and spin your spindle slow (like a drill press-1200-1800rpm) and drill slow (.25-.50ips)
    I learned from experience (hundreds of countertops) not to try to rush it.

    We will be receiving sample corian material as well as drilling/milling bits here soon for testing. The corian panels will be a vertical installation at the end so we want to also test tongue and groove for the best bond possible. I found a info sheet from DuPont from 2009 with tongue and groove bit sources; however, they are no longer valid. In addition, my favorite bit suppliers do not have what I believe I'm looking for. I believe I'm looking for a 4-flute smooth cut carbide tipped with 1/2" shank. Would any of you have recommendations on bits or experience with tongue and grooving corian?

    Thanks again for your replies.

    Also to note we will be using both 1/4" and 1/2" material. From what I understand, some bits can used for both thicknesses.
