Merit Abrasives 08834154120 Bore Polisher 120 Grit

Product Description

The MERIT ABRASIVES 08834154120 is a coated aluminum oxide bore polisher designed for finishing and polishing cylindrical bore surfaces. Rated at 15,000 RPM, it handles bores ranging from 2.5 to 3 inches in diameter with a fine 120-grit abrasive surface. The coated construction delivers consistent stock removal and surface refinement on metal bores. Machinists, tool and die technicians, and maintenance professionals use this type of tool to bring bore surfaces to a finished, polished condition after initial machining or honing operations.

This bore polisher is suited for use on engine cylinders, hydraulic cylinder bores, pump housings, and similar cylindrical metal components where surface finish consistency is required. The 120-grit fine grade makes it appropriate for final finishing passes rather than aggressive material removal. It is a single-unit packaged item intended for professional shop and field maintenance applications.

Key Features

• Coated aluminum oxide abrasive construction for consistent fine-grade finishing
• 120 grit fine grade suitable for final polishing passes on metal bores
• Rated to 15,000 RPM for use with standard pneumatic or electric rotary tools
• Fits bores from 2.5 to 3 inches in diameter
• No interleaf design for direct abrasive contact with bore surface

Compatibility

Designed as an OEM-style replacement or standard shop consumable for bore polishing applications on cylindrical metal surfaces in the 2.5 to 3 inch diameter range.

Installation Notes

Installation and operation of this bore polisher should be performed by qualified machinists or maintenance technicians familiar with rotary abrasive tooling. Verify that the spindle speed of the drive tool does not exceed the 15,000 RPM maximum rating before operation. Secure the workpiece properly before use and wear appropriate eye protection and gloves. Inspect the abrasive for damage or wear before each use and replace if any deterioration is observed.
