Lisle 36500 Cylinder Ridge Reamer (2 11/16 in to 5 5/16 in)

If you’re chasing cleaner cylinder work, a ridge reamer can be the difference between “good enough” and a smooth, controlled finish. The Lisle 36500 Cylinder Ridge Reamer is built for cutting away cylinder ridges with a steadier feel—thanks to how its rollers and stabilizer spring are set up.

This is one of those tools that feels pretty straightforward on paper, but it matters where it fits in your workflow: if you deal with cylinder prep, this style of reamer is aimed at reducing chatter and making the cut more selective rather than aggressive.

The essentials

The Lisle 36500 is a cylinder ridge reamer designed to work across a fairly wide range, specifically from 2 11/16 in to 5 5/16 in. It uses a “scraper action,” and the rollers are there to help turning in the cylinder feel easier and more controlled.

It also includes an exclusive stabilizer spring, which is meant to let the operator take a more selective cut. In practical terms, that’s the sort of feature you notice when you’re trying not to make the tool chatter or wander while you’re removing the ridge.

What you’ll notice in use

This tool’s main value is in how it aims to control the cut. Instead of relying only on manual pressure, the design includes rollers for easier turning and a stabilizer spring to help keep things steadier.

If you’ve ever had a ridge reamer start to chatter, you already know how annoying that can be. The Lisle 36500 is positioned to minimize that by supporting a more controlled, selective cutting approach. It’s not trying to be complicated—just more stable while you work.

A simple micro-scenario: you get your cylinder prepped and start addressing the ridge. With this kind of tool, you typically want consistent, repeatable removal. The “selective cut” intent is exactly what you’d hope for when you’re tuning how much material you remove and trying to keep the tool from getting noisy.

Key points

The Lisle 36500 Cylinder Ridge Reamer is made for cylinder ridge cleanup using scraper action, with rollers intended to make turning in the cylinder easier. It also includes a stabilizer spring that’s meant to help you take a more selective cut and minimize chatter during the job.

The wide working range (2 11/16 in to 5 5/16 in) makes it less of a single-size tool and more of a “covers more setups” option for typical cylinder work.

Where it shines (and where it may not)

This reamer makes the most sense if your focus is on cylinder ridge work and you want a tool designed around steadier turning and reduced chatter. If you’re the kind of person who cares about consistency while prepping cylinders, you’ll likely appreciate the stabilizer spring concept.

That said, it may not be the best choice if you only do occasional cylinder prep and don’t want to invest in a specialized tool. Also, if you’re expecting a tool to handle every cylinder scenario perfectly without attention to technique, it may feel limiting—like most reamers, results still depend on how you run the tool and how the cylinder is set up.

Quick overview of specs to check before buying

Before you commit, double-check the size range against your cylinder needs: this reamer is specified for 2 11/16 in to 5 5/16 in.

Also, consider how your work handles turning control. The rollers and stabilizer spring are core to the intended feel—if your setup already makes cutting very stable, you may not feel the difference as strongly as someone who’s struggled with chatter.

Practical tips for getting the most from it

Even with the stabilizer spring doing its job, take it slow and aim for consistency. The idea is to use that “selective cut” intent instead of forcing faster removal.

If chatter is a concern in your workflow, focus on controlled engagement and steady turning rather than abrupt pressure changes. That’s where the roller-assisted turning and spring stabilization are meant to help.
