Collection: Gesswein® Oil-Treated Stones

Oil-Treated Polishing Stones are a reliable, general-purpose option designed for efficient, consistent performance across a wide range of tool steels. Pre-saturated in an oil solution to minimize loading, these stones feature sharp white aluminum oxide abrasive that fractures during use, constantly exposing fresh cutting edges. Ideal for light EDM scale removal and finishing machined surfaces, they strike a balance between durability and effective stock removal. Their medium-hard composition and moderate breakdown rate make them a versatile choice for both mold and die applications.

Features:

• Pre-treated with oil to minimize loading during use
• Made with sharp white aluminum oxide abrasive for extended life
• Fractures cleanly to continually expose new cutting surfaces
• Excellent for polishing light EDM scale and machined surfaces
• Recommended for all tool steels: A2, D2, M2, S7, H13
• Medium-hard hardness with a moderate breakdown rate
• Suitable for wet use and limited dry applications
