Norton 69014191838 Cbn Grinding Wheel 3-3/4 in Type 11V9

Product Description

The NORTON 69014191838 is a Type 11V9 cubic boron nitride (CBN) grinding wheel engineered for precision tool grinding applications. Built on a resinoid bond platform under the Aztec III series, it carries a 100-grit Fine grade abrasive face with a superabrasive concentration of 75 and a 1/8-inch depth of CBN material. The wheel measures 3-3/4 inches in diameter with a 1-1/2 inch overall thickness, a 3/8-inch face width, and a 1-1/4 inch arbor hole. It is rated for both wet and dry operation, making it adaptable to most bench and pedestal tool-and-cutter grinder setups. Licensed HVAC, plumbing, and machine-shop technicians who sharpen carbide-tipped cutting tools will recognize this as a production-grade solution for maintaining tool geometry.

This wheel is designed for use on tool-and-cutter grinders where superabrasive performance is required to maintain edge integrity on hard tool steels and carbide. The 70-degree face angle geometry is suited for sharpening end mills, drills, reamers, and similar rotary cutting tools. The 2-21/32 inch hub diameter accommodates standard mounting flanges on bench-style tool grinders. Wet or dry coolant compatibility allows integration into both flood-coolant and dry-grind production environments, keeping heat generation and wheel loading under control during extended use cycles.

Key Features

• Cubic Boron Nitride (CBN) abrasive for long wheel life on hardened tool steels
• Resinoid bond provides controlled breakdown and consistent cut rate
• 100-grit Fine grade delivers smooth finish geometry on cutting edges
• Type 11V9 cup profile with 70-degree face angle for tool-and-cutter applications
• Rated for both wet and dry operation across varied grinder setups
• Aztec III series designation with 75 concentration for balanced stock removal and wheel longevity

Compatibility

Designed as an OEM-style replacement or direct-fit superabrasive wheel for bench and pedestal tool-and-cutter grinders accepting a 1-1/4 inch arbor bore and Type 11V9 cup wheel geometry.

Installation Notes

Mounting and dressing of CBN grinding wheels should be performed by a qualified tool-and-cutter grind technician following the grinder manufacturer's safety guidelines and ANSI B7.1 wheel-mounting standards. Power down and lock out the grinder before changing or inspecting the wheel. Do not exceed the maximum operating speed stamped on the wheel. Inspect the wheel for cracks or damage before each mounting; never use a damaged wheel.
