Century Drill Tool 75209 Mounted Grinding Point 3/4x1-1/4 in 3-pack

Product Description

The Century Drill Tool Co Inc 75209 is a mounted grinding point designed for material removal, deburring, and surface grinding on all types of metal. The abrasive wheel measures 0.75 inches in diameter by 1.25 inches in length and is constructed from vitrified aluminum oxide, a bonded abrasive well suited for ferrous and non-ferrous metals. The 0.25-inch round shank fits standard drill chucks, die grinders, and rotary tools without adapters. This package contains three grinding points. Machinists, fabricators, and maintenance technicians typically use these in production and repair workflows where a consistent abrasive profile is needed in tight cavities or on contoured surfaces.

These grinding points are used in metalworking applications including weld cleanup, port grinding, slot finishing, and general deburring. They are suited for bench-mounted rotary tools, handheld die grinders, and standard drill presses or cordless drills equipped with a chuck that accepts a 0.25-inch shank. The cylindrical profile makes them effective in bores, slots, and along straight edges where flat abrasive media cannot reach.

Installation Notes

Install the shank fully into the chuck or collet and tighten securely before operation. Inspect the grinding point for cracks or chips before each use and discard any damaged abrasive. Always wear appropriate eye protection and ensure the workpiece is clamped or secured. Match the tool RPM rating to the maximum rated speed of the grinding point to avoid abrasive failure.
