Description

APEXX Vacuum Brazed Diamond Sink Drum Wheels with Top Bearing – Coarse, Medium & Fine

Professional Template-Guided Sink Cutout Grinding & Stone Edge Shaping

Achieve precision and consistent grinding performance with APEXX Vacuum Brazed Diamond Sink Drum Wheels with Top Bearing. Designed for professional stone fabricators, these premium diamond grinding drums are ideal for shaping, smoothing, and refining sink cutouts and inside edges in natural and engineered stone materials.

Manufactured using advanced vacuum brazing technology, APEXX Sink Drums feature a durable diamond-coated grinding surface designed for efficient material removal and reliable performance.

Unlike standard sink drum wheels, these tools feature an integrated top bearing, allowing the drum to follow a template when used with compatible radial-arm machines. This provides improved guidance and control when grinding curved sink openings and shaped edges.

Key Features & Benefits

• Advanced Vacuum Brazing Technology: Durable diamond abrasive construction for efficient grinding and extended tool performance.
• Integrated Top Bearing: Designed for template-guided grinding on compatible radial-arm machines.
• Precision Sink Cutout Shaping: Ideal for refining sink openings, smoothing inside curves, and removing excess stone material.
• Consistent Grinding Profile: Diamond grinding surface designed to maintain its cylindrical shape during use.
• Multiple Diameter Options: Available in 1″, 2″, and 3″ diameters for different grinding applications.
• Coarse, Medium & Fine Grit Options: Select from available grits to match the desired grinding and finishing stage.
• 2″ Diamond Grinding Height: Extended diamond-coated working surface for effective edge grinding.
• 5/8″-11 Threaded Connection: Designed for compatible fabrication equipment.
• Versatile Material Compatibility: Suitable for granite, marble, engineered stone, porcelain, and ultra-compact surfaces.

Available Sizes & Grits

1″ Diameter — Coarse, Medium & Fine

Ideal for tight sink corners, smaller curves, and detailed grinding applications where precision is essential.

2″ Diameter — Coarse, Medium & Fine

A versatile option for general sink cutout shaping, inside edge grinding, and template-guided material removal.

3″ Diameter — Coarse & Medium Only

Designed for larger curved openings and more aggressive material removal where a wider grinding surface is preferred.

Understanding the Grit Options

• Coarse (#30): Ideal for initial shaping, rough grinding, and heavier material removal.
• Medium (#70): Designed for refining previously ground surfaces and reducing rough grinding marks.
• Fine (#140): Suitable for smoother edge preparation before additional finishing or polishing.

Ideal for Professional Stone Fabrication

APEXX Vacuum Brazed Diamond Sink Drum Wheels with Top Bearing are an excellent choice for countertop fabricators who need consistent, accurate results when shaping sink cutouts and curved stone edges.

The integrated bearing helps guide the grinding process along a template, while the vacuum brazed diamond surface delivers effective material removal and a durable grinding profile.

Whether you’re refining tight sink corners or shaping larger openings, these diamond sink drums provide the flexibility needed for demanding stone fabrication applications.

Important Operating Information: Wet use is required when working with engineered stone. Wet or dry operation is permitted on other manufacturer-approved materials. Always follow equipment speed limits, appropriate dust-control requirements, and manufacturer safety guidelines.
