Norton 69014191629 Type 12V9 Diamond Grinding Wheel 180 Grit

Product Description

The NORTON 69014191629 is a Type 12V9 diamond grinding wheel designed for precision grinding of hard and superhard materials. Built with synthetic diamond abrasive bonded in a resinoid matrix, it delivers consistent stock removal and fine surface finish at 180 grit, classified as Very Fine grade. The wheel measures 4 inches in diameter with a 0.5 inch overall thickness, a 1.25 inch hole, and a 2.25 inch hub diameter. The 30-degree face angle and 0.25 inch face width make it well-suited for form grinding, tool sharpening, and edge prep applications. It supports both wet and dry operation and carries a superabrasive depth of 0.125 inches with 100 concentration synthetic diamond. Machinists, tool and cutter grinders, and carbide tooling technicians are the primary users.

This wheel is used in precision tool grinding applications where a controlled, fine finish is required on carbide, ceramic, or other hard materials. The Type 12V9 profile is a standard choice for sharpening single-point and multi-point cutting tools, end mills, reamers, and similar tooling on surface, cylindrical, or dedicated tool and cutter grinding machines. Both wet and dry grinding modes are supported, giving flexibility across different shop setups. The 180-grit diamond abrasive makes this wheel appropriate for finish grinding passes rather than heavy material removal.

Installation Notes

Wheel mounting and dressing should be performed by a qualified machinist or tool grinder in accordance with ANSI B11.9 and applicable shop safety standards. Power down and lock out the grinding machine before mounting or changing the wheel. Inspect the wheel for cracks or chips before installation and never exceed the rated operating speed marked on the wheel. Use the correct flanges and blotters for secure, balanced mounting.
