It cuts up to 0.551 in (14.0 mm) deep and is 2.283 in (58.0 mm) long overall.\u003c\/p\u003e\n\n\u003ch3\u003enACo coating, polished O-flute\u003c\/h3\u003e\n\u003cp\u003enACo is a micro-thin ceramic coating that keeps the cutting edge sharp and slick, so aluminum skins cut clean instead of smearing or building up on the edge. The single polished O-flute gives chips plenty of room to clear, and the upcut direction pulls them up and out of the cut.\u003c\/p\u003e\n\n\u003ch3\u003eStop ring for the ARC bit changer\u003c\/h3\u003e\n\u003cp\u003eThe stop ring sets the bit's depth in the collet, so the RM-A QC ARC automatic bit changer loads it at the same height every time. For a router without ARC, the standard \u003cstrong\u003eRs403\u003c\/strong\u003e is the same bit without the ring.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\n\u003ch4\u003eHow do I know this fits my machine?\u003c\/h4\u003e\n\u003cp\u003eThe Rs403a has a 0.236 in (6.0 mm) shank and a stop ring for the Zund RM-A QC ARC automatic bit changer. Not sure which router you have? Send us your machine model and we will confirm before you order.\u003c\/p\u003e\n\n\u003ch4\u003eWhat materials does it cut?\u003c\/h4\u003e\n\u003cp\u003eACM panels such as Dibond, Alucobond, Alumalite, and Maxmetal. For acrylic or foam, a different bit geometry is the better call. Reach out and we will help you pick the right one.\u003c\/p\u003e\n\n\u003ch4\u003eWhat speeds and feeds should I run?\u003c\/h4\u003e\n\u003cp\u003eMaximum spindle speed is 50,000 RPM. The right feed rate depends on the panel, its thickness, and your machine. If you need help dialing in settings, contact us. We run these machines every day.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I know when to replace it?\u003c\/h4\u003e\n\u003cp\u003eWatch the edge finish. Burrs on the aluminum skin, a fuzzy core, or aluminum building up on the cutting edge all mean it is time for a fresh bit.\u003c\/p\u003e\n\n\u003ch3\u003eGetting the most from your cutting table\u003c\/h3\u003e\n\u003cp\u003eA fresh bit is a good start. But if you are going through bits faster than expected, or edge quality has become inconsistent, the bit is rarely the whole story. Spindle speed, feed rate, depth per pass, material hold-down, and machine condition all affect how long a bit lasts and how clean it cuts.\u003c\/p\u003e\n\n\u003cp\u003eIt is worth asking: When was your machine last serviced? Are your parameters dialed in for this material? Is this the right bit for what you are cutting? Could your operators use time with someone who runs these machines every day?\u003c\/p\u003e\n\n\u003cp\u003eFlatbed Tools offers machine service, preventive maintenance, operator training, and workflow consulting. If something is not cutting right, reach out.
