Dremel DSM510 77 mm Cutting Disc Pack — 3 Reinforced Discs for DSM20 Circular Saw

Overview

The DSM510 is a reinforced cutting disc designed for the Dremel DSM20 compact circular saw and compatible rotary tools. With an outer diameter of 77 mm and a 20 mm bore, these type 1 abrasive discs deliver stable, controlled cuts across a variety of materials. This three-disc multipack keeps you prepared for ongoing projects without swapping components mid-task.

Why this set stands out

• Plunge-cut capability with reduced kick-back, supported by thoughtful disc geometry for precise starts and predictable progress.
• Cooling holes help manage heat buildup, promoting cleaner edges and steadier cutting in metal and plastic.
• Three-disc multipack ensures you have spare discs on hand, reducing breaks in workflow.

What you can cut

These discs are suitable for metal and other materials, including copper pipe, cables, coated gratings, sheet metal, threaded rods, and aluminum sheets. When used with the DSM20, they also support straight cuts and controlled plunge cuts in wood and other soft materials.

Usage tips

• Wear proper eye and face protection, and secure your workpiece before starting the cut.
• Maintain steady, moderate feed pressure and let the disc do the cutting for a clean edge.
• Periodically cool the workpiece to minimize overheating and prolong disc life.

Compatibility and care

Designed for the Dremel DSM20 compact circular saw and most rotary tools with a 3.2 mm shank. Inspect discs for wear and replace when the edge dulls or heat buildup becomes noticeable.
