Weha Blitz 4″ Resin Filled Diamond Cup Wheel

Overview

The Weha Blitz 4″ Resin Filled Diamond Cup Wheel series is a professional-grade set of diamond-impregnated grinding wheels engineered specifically for chip-free grinding and shaping of natural stone and engineered surfacing materials such as granite, marble, quartz, and similar hard stones. Built with resin-filled diamond technology, these cup wheels deliver smooth, balanced cutting action and extended tool life, making them a trusted choice for fabricators, restoration specialists, and stone professionals.

Available in the Coarse (SKU 7685), Medium (SKU 7686), and Fine (SKU 7687) grit variants, this group lets you tailor your grinding workflow — from aggressive material removal to intermediate preparation and fine surface refinement — all with consistent performance and minimal vibration.

Product Description

The Weha Blitz 4″ Resin Filled Diamond Cup Wheel series is specifically designed for precision shaping, grinding, and surface preparation of natural and engineered stones, including granite, marble, quartz, and other hard surfacing materials. Engineered with advanced resin-filled diamond segments, these cup wheels deliver a smooth, controlled, and chip-free grinding action that reduces material stress and enhances the overall finish of the stone.

Ideal for stone fabricators, restoration specialists, countertop installers, and professional masons, the Blitz series provides consistent performance across a variety of applications, from edge profiling and beveling to leveling and smoothing stone surfaces. The resin-filled design ensures exceptional bond strength and heat dissipation, extending the life of the wheel while maintaining sharpness and grinding efficiency over prolonged use.

With a 4-inch diameter, these cup wheels offer excellent maneuverability and precision, allowing operators to work on intricate edges, tight corners, and larger surface areas with confidence. The balanced construction minimizes vibration and enhances control, resulting in a smoother finish and reduced operator fatigue.

Whether used for initial stock removal, shaping complex stone profiles, or preparing surfaces for polishing and finishing, the Weha Blitz 4″ Resin Filled Diamond Cup Wheel series delivers reliable, professional-grade results. This makes it an indispensable tool for workshops, fabrication facilities, and on-site stone projects, providing a combination of durability, precision, and efficiency that professionals can depend on.

Key Features

Resin-Filled Diamond Construction

High diamond concentration embedded throughout the wheel for even stock removal and consistent cutting feel.
Resin bond offers a smoother grinding action with reduced risk of chipping compared with segment-only designs.

Balanced and Smooth Running

Precision balancing minimizes vibration and “wobble” during operation for enhanced control and surface contact.
Works well on both wet and dry grinding tasks depending on jobsite conditions.

Standard 5/8″‑11 Thread

Fits most angle grinders or grinders with a 5/8″‑11 threaded arbor, standard in stone fabrication shops.
Rated up to 10,000 RPM, giving flexibility across tools.

Multiple Grit Variants

This series includes three grit choices to match different stages of surface preparation:

• Coarse (SKU 7685) — aggressive cutting, faster material removal.

• Medium (SKU 7686) — balanced material removal with smoother finish.

• Fine (SKU 7687) — finer surface preparation and surface refinement prior to polishing.

Typical Uses

• Aggressive Stock Removal: The coarse variant quickly removes high spots, transitions, and excess material.

• Surface Preparation: Medium grit helps smooth out surfaces after rough grinding before moving to increasingly refined tools.

• Fine Finishing Prep: Fine grit provides a cleaner, more refined surface before polishing or sealing.

• Jobsite and Shop Work: All grit variants perform well in shop tables or handheld grinders under varying conditions (wet/dry).

Performance Notes

Wet grinding can help reduce dust and prolong wheel life, particularly for extended grinding work.
Match your grit progression to the task: start coarse for rough shaping, medium for general grind work, then fine before polishing.
Use appropriate PPE (eye protection, respirator) to mitigate stone dust during dry grinding.

Summary

The Weha Blitz 4″ Resin Filled Diamond Cup Wheel variant group delivers smooth, chip-free grinding and controlled material removal across three grit options — Coarse (7685), Medium (7686), and Fine (7687) — to support professional stone fabrication workflows. With balanced rotation, resin-bonded diamonds, and compatibility with standard grinders, this series provides versatility and consistent performance for granite, quartz, marble, and other natural stone surfaces.
