Electroplated diamond mounted points are small rotary grinding tools (mounted points/rotary burr-like shapes) in which a single, dense layer of diamond crystals is electrodeposited (usually nickel-based) onto a shaped metal shank or head. The metal shank is sized to fit standard die grinders, flex shafts, or bench rotary tools.
Shapes: common shapes include cones, cylinders, spheres, tapered points, bullet shapes, and wheels — selected to reach contours, holes, slots and profiles.
Construction: a steel or brass shank with a machined head that is plated with a monolayer of diamond grit fixed in a metal matrix. The plating exposes sharp diamond edges at the surface for immediate cutting.

Electroplated diamond mounted points are compact, durable rotary tools with a surface layer of exposed diamonds plated onto a metal head. For cast iron work they provide aggressive, precise cutting for deburring, detail grinding, small-profile shaping and touch-up repairs with low loading and good finish. They’re best used for light-to-moderate removal and fine-detail work rather than bulk material removal; proper grit choice, coolant, and gentle technique maximize life and results.
