Brunidor de cilindros ks tools 150.1185, diâmetro 19–69 mm, brunidor manual ajustável

Cylinder hone tool ks tools 150.1185 is a manual adjustable hone with a working diameter range of 19–69 mm. Designed for finishing and resurfacing cylinder bores, it delivers controlled material removal and creates a uniform crosshatch pattern to improve sealing and oil retention. The tool is suitable for automotive, motorcycle and small engine maintenance and is intended to restore bore geometry, remove glazing and light scoring, and prepare surfaces for new piston rings or coatings.

Advantages

The adjustable manual hone provides a wide working diameter range, enabling use across various cylinder sizes without the need for multiple dedicated tools. Its mechanical construction allows precise control over abrasive engagement, resulting in consistent surface finish and minimized risk of over-removal when used correctly. The design supports uniform crosshatch patterns that promote better lubrication and sealing. As a hand-operated tool, it offers portability and straightforward operation in workshop or field conditions.

Suitable for

• Finishing and resurfacing engine cylinder bores
• Restoring bore geometry on cars, motorcycles and small engines
• Removing glazing, light scoring and deposits before ring replacement
• Preparing cylinder surfaces for honing, plating or coating processes

Key specifications

• Working diameter range: 19–69 mm
• Operation: manual / hand-operated
• Adjustable abrasive stones for variable expansion
• Intended use: finishing and resurfacing of cylindrical bores
• Typical materials: cast iron and aluminum engine bores (with appropriate abrasives)

How to use

Secure the hone in the bore and set the tool to the required diameter within the 19–69 mm range, ensuring even contact of the abrasive stones with the cylinder wall. Use steady, controlled strokes and maintain consistent pressure while rotating the tool slowly to generate an even crosshatch pattern. Apply an appropriate cutting or honing oil to carry away swarf and reduce heat during the process. Periodically retract and clean the stones to remove debris, check the surface condition, and adjust expansion as needed until the desired finish and geometry are achieved.

Recommendations

For best results, choose abrasive stones suited to the cylinder material and the degree of material removal required. Use proper safety equipment and follow workshop procedures for engine disassembly and reassembly. Avoid excessive pressure or prolonged application in one area to prevent over-sizing or uneven surfaces. After honing, thoroughly clean the cylinder to remove abrasive residues before fitting new piston rings or reassembling the engine.
