Lisle Cylinder Ridge Reamer 2 11/16"–5 5/16" Heavy‑Duty Spring‑Loaded Carbide Cutter, Roller Stabilizer

This professional-grade tool combines a wide cutting range with a spring-loaded carbide cutter and stabilizing features to let mechanics and DIYers remove ridge buildup without overcutting. Designed for repeatable performance, the reamer uses rollers and offset jaw guides to stay centered while the stabilizer spring lets you take light or heavier passes as needed. It's a compact, single-package solution for preparing cylinders before hone or ring replacement.

How does the Lisle reamer remove cylinder ridges safely?

The tool follows the cylinder contour with a spring-loaded carbide cutter that only engages as needed, reducing the risk of digging in. Rollers help the unit spin easily so cuts are smooth and consistent, while the stabilizer spring lets you control the aggressiveness of each pass.

• Spring-loaded carbide cutter tracks cylinder profile
• Rollers create low-friction turning for consistent cuts
• Stabilizer spring enables controlled, selective cutting
• Offset jaw guides maintain rigidity across the range

What cylinder sizes and applications does this reamer cover?

The 36500 covers a broad diameter span from 2 11/16" to 5 5/16" (68.3–134.9mm), making it suitable for many automotive and small-engine cylinders. That range fits the majority of passenger car bores and several light-duty engines, allowing one tool to serve multiple jobs.

• Range: 2 11/16" to 5 5/16" (68.3–134.9mm)
• Works on standard passenger vehicle cylinders and many small engines
• Single-unit alternative to carrying multiple fixed cutters

How many passes and adjustments are typically needed?

Because the cutter is carbide and spring-loaded, most ridges come out in just a few controlled rotations rather than many aggressive cuts. The stabilizer spring and adjustable engagement let you dial in a light skim or a heavier cut depending on ridge severity; inspect frequently to avoid removing more material than necessary.

• Complete ridge removal often in only a few turns
• Stabilizer spring for incremental cutting control
• Inspect cylinder frequently between passes to preserve bore integrity

What build features improve durability and usability?

Lisle engineered this reamer for shop use: carbide cutting edges resist wear, rollers reduce operator effort, and offset jaw guides keep the tool rigid across its entire span. The compact package dimensions make it easy to store in a toolbox while still offering heavy-duty performance.

• Carbide cutter for long-lasting edge retention
• Rollers reduce torque required to turn in the cylinder
• Offset jaw guides maintain alignment and rigidity
• Compact packaging for tidy storage and transport

Who is this for: the Lisle 36500 cylinder ridge reamer is built for professional mechanics, automotive hobbyists, and technicians who need a reliable, single-tool solution for ridge removal across a wide range of cylinder sizes. It suits users who prefer precise, controlled material removal with durable cutting components and straightforward operation, especially when preparing bores for honing, ring replacement, or further machining.
