RUBI 06986 Diamond Tapered Reamer 2-35mm

The RUBI 06986 Diamond Tapered Reamer 2-35mm is a professional-grade accessory engineered specifically for enlarging, shaping, and beveling existing holes in hard materials such as porcelain, ceramic tiles, and natural stone. Featuring a working diameter range from 2 to 35 mm, this specialized tool allows tradespeople and installers to achieve precise adjustments for plumbing fixtures, pipes, drains, and electrical outlets directly on the job site without risking cracking or damaging the surrounding material.

Advantages

This diamond tapered reamer offers exceptional durability and precise material removal thanks to its high-quality diamond abrasive coating. Its continuous conical design provides a smooth transition across various diameters, reducing the need for multiple separate bits. The tool delivers clean edges, minimizing chipping on delicate glazed surfaces and hard stone tiles. Designed for efficient performance, it helps professionals save time during complex installations while maintaining high accuracy and a professional finish.

Suitable for

• Enlarging existing holes in porcelain stoneware and ceramic tiles
• Shaping and beveling openings for plumbing pipes and drains
• Fitting electrical outlets and cables through hard tile surfaces
• Adjusting holes for sanitary installations in natural stone

When it may not be suitable

This tool is not designed for drilling completely new holes from scratch, as it functions primarily as a reamer and shaper for existing openings. It is also not intended for use on soft materials like wood, plastics, or non-rigid substrates where diamond abrasive action is unnecessary or potentially damaging.

Key specifications

• Working diameter: 2 to 35 mm
• Application: Enlarging, shaping, and beveling holes
• Compatible materials: Porcelain, ceramic tiles, and natural stone
• Tool type: Diamond tapered reamer

How to use

To use the RUBI diamond tapered reamer, securely attach it to your power tool following the manufacturer guidelines. Begin by aligning the tapered tip with an existing pilot hole in the tile or stone. Apply steady, moderate pressure while gently moving the tool in a circular or orbital motion to gradually expand the opening to the desired diameter. Avoid applying excessive force to prevent overheating and to ensure an even, clean bevel along the edge of the hole.

What to consider before purchase

• Verify that your existing hole sizes fall within the 2 to 35 mm working range
• Confirm compatibility with your drilling or power equipment setup
• Ensure the target material matches recommended surfaces such as porcelain or natural stone

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and respiratory protection, when dry or wet grinding hard materials. Use water cooling if recommended for your specific setup to extend the working lifespan of the diamond abrasive coating and reduce dust generation.
