Dremel 7105 Diamond Ball Mounted Point 1/8 in Shank

Product Description

The DREMEL 7105 is a diamond ball mounted point designed for precision grinding, shaping, and detailing on hard materials. Fitted with a 1/8 inch shank diameter and 0.4 inch shank length, it seats securely in standard rotary tool collets. The ball-shaped diamond abrasive tip delivers controlled material removal on surfaces where conventional abrasives fail or wear too quickly. Rated to 35,000 RPM, it maintains cutting performance at high speeds without excessive heat buildup. At 1.2 inches overall length and just 0.01 pounds, the 7105 is a lightweight point suited for close-tolerance work performed by machinists, jewelers, tile setters, and tool-and-die professionals.

This mounted point is suited for grinding and finishing operations on ceramic, glass, hardened steel, jade, semi-precious stones, and other hard materials that require diamond-grade abrasion. Typical applications include deburring hardened metal components, enlarging or refining holes in ceramic tile and glass, carving detail in stone or lapidary work, and smoothing weld seams on tool steel. It is sized for handheld rotary tools commonly used on the bench or in the field.

Installation Notes

Installation is performed by a machinist, jeweler, or trade professional using a standard rotary tool with a compatible collet. Power down and unplug the rotary tool completely before inserting or removing the mounted point. Tighten the collet nut securely to prevent slippage at operating speed. Always wear eye protection when operating diamond abrasive points at high RPM.
