This is a replacement pin for a hand-operated grindstone dresser (Draper Tools Group D). Its primary use is to locate and retain the dresser elements that profile and true abrasive wheels, replacing worn or damaged pins that secure the dresser head, studs or dressing tool to the body of the dresser assembly.

The pin is manufactured from medium-carbon steel, heat‑treated and surface finished for wear resistance and dimensional stability. Typical material specification is in the range of C45/EN8 class steels with a hardened and tempered surface; a black phosphate or oil‑quenched finish is applied to reduce surface corrosion and abrasion. The component is a plain cylindrical (non‑threaded) pin with a chamfered seating face and a turned nominal diameter to suit Draper Group D dresser housings; it is designed to be retained by the dresser’s existing grub screw, circlip or locating plate rather than by an integral drive or thread.

Where applicable, material selection and heat treatment conform to common workshop steel standards and practice (referencing EN/BS guidelines for quenched and tempered carbon steels such as EN ISO 683‑1 / BS EN 10083 for comparable materials). The pin is made to typical DIN/ISO dimensional practice for replacement pins so it will fit standard Draper dresser spare positions without modification.

Typical applications are in metalworking and toolroom environments for dressing bench and pedestal grinder wheels in engineering workshops, maintenance departments, toolmaking shops and agricultural or vehicle repair garages. The pin’s wear resistance and accurate diameter ensure consistent wheel profiling and safety in abrasive wheel maintenance operations.

Key benefits include a hardened core and wear‑resistant surface to extend service life compared with mild steel replacements, a corrosion‑resistant finish for workshop conditions, and form compatibility with Draper Tools Group D dresser assemblies. Stainless variants can be sourced where elevated corrosion resistance is required.
