JONAS C Diamond Beveling Chamfer Bit Set – 2-Inch Tile Cone Bit + 0.8-Inch Diamond Finger Milling Bit, 3/8-Inch Hex, 5/8-11 Thread

Upgrade your tile and stone projects with the JONAS C Diamond Beveling Chamfer Bit Set. This compact duo is designed to help you achieve clean bevels and precise trims on ceramic, tile, stone, and glass surfaces. By pairing a diamond cone tile bit with a diamond finger milling bit, you gain two specialized tools in one affordable package, enabling smoother workflows from edge prep to final finishing.

What’s included

• Diamond Cone Tile Bit — maximum diameter 2 inches; working diameter 0–50 mm; 60° bevel; total length 2.1 inches (53 mm); working depth 1.7 inches (43 mm); weight 0.55 lb; grit 80.
• Diamond Finger Milling Bit — diameter 0.8 inches (20 mm); total length 2.75 inches (70 mm); working length 2 inches (50 mm); weight 0.33 lb; grit 45.

What it does

• Beveling, chamfering, countersinking, hole enlarging, edge trimming, shaping, and grinding on hard brittle materials such as tile, ceramic, stone, and glass.
• The cone bit creates a 60° rounded bevel, while the finger milling bit produces a flat plane for finishing touches.

Tool compatibility and usage

The set uses a 5/8-inch-11 thread that fits most angle grinders. A 3/8-inch hex shank adapter is included to connect with standard power drills. For some materials, higher RPM may be required; angle grinders are typically preferred for stability.

Key application notes:

• Supports hole diameters from 0 to 2 inches (0–50 mm), reducing the need for multiple bits and saving time.
• Suitable for both dry and wet grinding, depending on material and setup.

Technology and durability

Braze-bonded diamond technology delivers strength and long-lasting durability. Diamond particles are directionally aligned to distribute cutting force evenly, helping minimize edge chipping. With 80% diamond exposure height, abrasive utilization is optimized, contributing to efficient material removal across tile, ceramic, stone, and glass surfaces.

Whether you’re refining tile edges in a kitchen, beveling edges for a bathroom backsplash, or trimming stone details for a crisp finish, this set offers precision and versatility without clutter. Always follow safety guidelines and choose the right RPM for your material and tool to achieve best results.
