Cutting Disc 65 mm HSS for Proxxon OZI/E Grinder PR28900

The Cutting Disc 65 mm HSS for Proxxon OZI/E Grinder PR28900 is a small-diameter high-speed steel cutting wheel designed for precision metalworking on the Proxxon OZI/E compact grinder. Intended for fine cutting, trimming and detail operations, this 65 mm HSS disc offers a narrow kerf and stable cutting action on small workpieces and model-making components. The disc is compatible with tasks that require controlled, accurate cuts on both soft and harder metals when using the Proxxon OZI/E tool.

Advantages

Constructed from high-speed steel (HSS), the disc provides sharp, durable cutting edges that retain form under heat and repeated use. Its 65 mm diameter and slim profile allow close access to tight areas and precise control for detailed trimming. The design reduces chatter and improves cut quality on small parts, while the material selection supports cutting across a range of metallic materials without rapid dulling.

Suitable for

• Model making and miniature metal parts cutting
• Fine trimming and profiling of small metal components
• Precision cuts on soft steels, brass, copper and similar metals
• Repair work on small assemblies and hobby projects

Key specifications

• Disc diameter: 65 mm
• Material: high-speed steel (HSS)
• Intended use: precision metal cutting and trimming
• Compatible tool type: compact rotary grinder with appropriate arbor size
• Profile: thin cutting disc for narrow kerf and fine control

How to use

Mount the 65 mm HSS cutting disc on the Proxxon OZI/E grinder following the tool manufacturer's mounting instructions and ensuring the disc is secured to the correct arbor. Verify the rotation direction and set a moderate grinder speed suitable for small-diameter metal cutting. Hold the workpiece firmly or secure it in a vise, approach the cut with steady, controlled feed, and avoid excessive pressure to prevent overheating or premature wear. Allow the blade to perform the cut at its own pace and back off periodically to inspect progress and clear chips.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves and hearing protection) and maintain proper ventilation when cutting metals. For best results, choose cutting speeds recommended for small HSS discs and avoid forcing the disc through thick sections; multiple shallow passes give more accurate results and extend disc life.
