Lisle Engine Cylinder Hone 15000 — Micrometer-Controlled 3"–4¼" Bore Kit with Coarse & Medium Stones

This professional-grade cylinder hone combines a micrometer feed, quick-expanding rack-and-pinion action and a protective bottom plate so you can dress or recondition engine bores accurately and safely. It ships with coarse and medium stones, a cleaning brush and a dressing paddle in a durable case, ready to use with a heavy-duty 1/2" drill. The tool’s universal joint and long stone options make it adaptable for tight clearances and longer cylinders.

How does the Lisle 15000 ensure accurate bore sizing?

The micrometer head provides precise, incremental feed so you can control stone penetration and finish. Combined with the rack-and-pinion expansion, the hone opens quickly to the target diameter and holds it consistently while you work.

• Micrometer head for fine adjustments and repeatable passes
• Fast-action rack-and-pinion expansion to reach target size quickly
• Standard range set for 3"–4¼" bores with optional racks for larger sizes
• Longer 5" stones available for faster, truer cuts in deeper cylinders

What safety and convenience features prevent damage during honing?

A bottom guard plate shields the crankshaft and internals from loose abrasive stones, while clip-on stones and wipers allow quick servicing without tools. The included cleaning brush and dressing paddle make stone upkeep simple and help maintain consistent performance.

• Bottom guard plate reduces risk of stones contacting crankshaft
• Clip-on stones and wipers change in seconds for minimal downtime
• Cleaning brush and dressing paddle keep stones cutting efficiently
• Sturdy storage case protects components between jobs

Which drills and bore sizes work with this hone?

Use the Lisle 15000 with a heavy-duty 1/2" drill for steady rotational speed and torque. The tool’s standard rack fits 3"–4¼" cylinders; additional rack and stone sets extend the range from approximately 2 3/4" up to 10 1/4" when needed.

• Designed for use with heavy-duty 1/2" drills
• Standard rack covers 3"–4¼" bores out of the box
• Optional racks and stone sets expand range to 2 3/4"–10 1/4"
• Long stones available for improved speed and accuracy in large/long cylinders

How do the stone grits affect the finish and applications?

Stones come in multiple grits so you can choose rapid material removal or a finer crosshatch for final honing before assembly. The kit includes coarse and medium stones; five-grit options are available to match different job needs from heavy stock removal to final surface preparation.

• Coarse stones for fast material removal and resizing
• Medium stones for blend and smoothing operations
• Finer grits (sold separately) for final crosshatch and sealing surfaces
• Clip-on design makes grit swaps quick and tool-free

Who is this for: The Lisle 15000 Engine Cylinder Hone is aimed at home mechanics, professional engine rebuilders and hobbyists who need a reliable, adjustable hone for small- to medium-diameter cylinders.
