It has a 0.236 in (6.0 mm) shank, 0.118 in (3.0 mm) cutting diameter, 0.433 in (11.0 mm) cutting length, and 1.969 in (50.0 mm) overall length. If your router runs the R123 now, the Rs123d drops straight in. Not sure? Contact us before you order.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this bit is built for\u003c\/h3\u003e\n\u003cp\u003eZund lists the R123 for acrylic and aluminum. The downcut spiral pushes chips down into the cut instead of lifting them, which leaves a clean top edge with less chipping on the face of the sheet. The 0.118 in (3.0 mm) diameter holds tighter inside corners and finer detail than the 0.157 in (4.0 mm) Rs124d.\u003c\/p\u003e\n\n\u003ch3\u003eSingle O-flute, downcut\u003c\/h3\u003e\n\u003cp\u003eOne large O-flute gives chips the most room to clear, which keeps heat down and helps stop acrylic from melting behind the bit. Because a downcut bit packs chips into the kerf, deep cuts may need a clearance pass.\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 Rs123d fits Zund RM-L, RM-A, RM-A QC, RM-S, and R45-s router modules that take the \u003cstrong\u003eZund R123\u003c\/strong\u003e. It has a 0.236 in (6.0 mm) shank. It is the standard version without the stop ring, so it is not for the RM-A QC ARC automatic bit changer. If you are not sure which router module 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\u003eAcrylic and aluminum. If the bottom edge matters more than the top, an upcut bit 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 material, 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 and the chips. Chipped top edges, burrs on aluminum, melted or re-welded edges on acrylic, or fine powder instead of clean chips 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.
