The Lisle 36500 combines a carbide cutting element, stabilizer spring, and roller-guided offset jaws so technicians can shave a ridge with minimal chatter and consistent contact against the bore contour. It’s built to cover a wide diameter range and to deliver a smooth scraping motion with just a few rotations.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this reamer remove a cylinder ridge without damaging the bore?\u003c\/h3\u003e\n\n\u003cp\u003eThe tool uses a spring-loaded carbide cutter that follows the cylinder's contour while offset jaw guides keep the unit rigid across its full range. Rollers let the tool rotate easily, while the stabilizer spring lets the operator take incremental cuts rather than removing too much material at once. The combined design reduces vibration and helps maintain a true surface on the bore.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSpring-loaded carbide cutter contours to the bore for consistent contact.\u003c\/li\u003e\n  \u003cli\u003eStabilizer spring enables selective, controlled cutting to minimize chatter.\u003c\/li\u003e\n  \u003cli\u003eRoller-bearing support allows smooth rotation and even scraping.\u003c\/li\u003e\n  \u003cli\u003eOffset jaw guides maintain rigidity across the full 68.3–134.9mm range.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat cylinder sizes will this Lisle reamer handle?\u003c\/h3\u003e\n\n\u003cp\u003eThis model adjusts to cover diameters from 2-11\/16\" up to 5-5\/16\" (68.3–134.9mm), making it suitable for many passenger cars, light trucks, small engines, and some industrial cylinders.

Use short, controlled cuts with the stabilizer spring engaged to avoid removing excess material; inspect frequently until the ridge is cleared.

It’s particularly useful for shops that work on a variety of small- to medium-diameter cylinders and want a single, durable reamer to handle multiple bore sizes. The Lisle 36500 is packaged as a single unit and is manufactured to provide a practical balance of range, rigidity, and cutter durability.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this reamer handle oversized cylinders?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The Lisle 36500 adjusts from 2-11\/16\" to 5-5\/16\" (68.3–134.9mm).
