Ranger Cutting Tips - Fits RL-8500 and RL-8500XLT Brake Lathes Ranger Carbide Cutting Tips for RL-8500 and RL-8500XLT Brake Lathes These are six-sided carbide inserts for Ranger's RL-8500 and RL-8500XLT bench brake lathes, and the six sides are the point. An insert with six edges is indexable: when the working edge dulls, the tip is loosened, rotated in its seat and clamped again, presenting an unused edge to the work. The tip is not thrown away because one corner is finished — it is turned round, and only retired when the edges genuinely are. That single geometric fact governs both the economics of the part and the quality of the work coming off the lathe, and it is worth spelling out what each means in a working shop. A dull edge does not cut, it rubs Carbide cuts cast iron cleanly right up until it does not. The failure is gradual and it is easy to work through without noticing, which is why so many resurfacing complaints trace back to a tip that should have been indexed a week earlier. As the edge rounds over, it stops shearing material and starts pushing it. Cutting force rises, the tool and the rotor heat up, and the surface it leaves changes character — rougher, less consistent, sometimes with a burnished sheen where the edge has smeared metal rather than removing it. The consequences land later and land on somebody else. A pad has to bed onto that surface. A glazed or inconsistent finish gives uneven bedding, uneven deposit transfer and, before long, a customer describing a judder that appeared "after the brakes were done". A fresh edge is far cheaper than the diagnosis of that complaint, let alone the second set of rotors. Positive rake, and why the lathe feels different with fresh tips These tips use a positive rake geometry, which means the cutting face is angled so the edge slices into the material rather than scraping at it. The practical effect is lower cutting force for the same depth of cut. Lower force means less deflection in the tool holder and the arbor, less heat put into the rotor, and cleaner chip evacuation instead of material packing around the tip. On a bench lathe that matters more than on a big machine tool, because the whole assembly — arbor, adapters, rotor, holder — is a stack of parts, and every unnecessary pound of cutting force is a pound trying to flex that stack. Anyone who has watched a tired tip produce chatter and then watched a fresh one cut the same rotor silently has seen this happen. Mounting: two screws, and they matter Each tip is held by two screws rather than one. A single screw allows a tip to pivot minutely under load, however tight it is; two screws fix it in position and in rotation. Rigidity at the tip is what stops vibration turning into a visible pattern on the rotor face, and it is the reason a properly seated insert on a modest lathe outperforms a loose one on a better lathe. Two habits get the most out of that. Clean the seat before the tip goes in — a single chip trapped under an insert tilts it and undoes the precision of everything upstream. And tighten to a firm, even feel on both screws rather than cranking one down first, which can rock the tip in the pocket. Fitment and quantity Specified for the RL-8500 and RL-8500XLT. Insert pockets are machined to a specific insert shape and thickness, so this is not a place for near-enough substitution: a tip that does not seat flat and square cuts at the wrong height relative to the workpiece centreline, and the finish suffers no matter how sharp it is. On quantity, we will be precise about what we know. The copy supplied with this item states ten cutting tips to a package. The spec sheet in our data publishes only the carton size and weight — 4" x 2" x 1" (101 mm x 50 mm x 25 mm) at 1 lbs. — and does not state a count of its own. If you are ordering to a maintenance schedule or stocking for a run of work, confirm the pack quantity with us first rather than relying on a figure we cannot independently verify. Perfect for Brake specialists resurfacing daily, where tip condition is a scheduled item and not a surprise. General repair shops that machine in-house and want a consistent finish across every job. Any lathe producing chatter or a poor finish — indexing to a fresh edge is the first and least costly test. Keeping stock on the shelf, so a dull tip never stops the machine mid-week. What is in the box Six-sided carbide cutting tips for the RL-8500 and RL-8500XLT, in a carton of 4" x 2" x 1" (101 mm x 50 mm x 25 mm) at 1 lbs. Mounting screws are not listed as included and we are not going to imply that they are; if you need screws, ask and we will check the current parts list.

On a machine consumable that is entirely ordinary — there is no safety listing to be had for a carbide tip — but the rule holds across everything we sell: if the manufacturer's data does not claim a listing, our page does not mention one in either direction. Shipping and delivery This item ships free within the lower 48 states, so there is nothing to add at checkout. A carton this small travels as a parcel in all normal circumstances. Open it on arrival and check the contents against your order; in the unusual event it comes by freight, note any damage on the bill of lading before signing rather than after. Residential delivery is a different service from a commercial dock and carries a residential fee where it applies, and warehouse collection is available at the locations listed further down this page. Warranty Ranger's published warranty document for its product line applies here. We hold the document rather than a summary of its terms, so no period is stated on this page — ask us for the current copy if it matters to your order. It is worth being realistic about what a warranty covers on a consumable: carbide is a wear item, and an edge that has done its work has not failed. A tip that arrives chipped, cracked or wrongly dimensioned is a different matter, so inspect them before use and tell us straight away rather than running a damaged insert.
