Norton 69014192293 Type 11V9 Diamond Wheel 3 in 150 Grit

Product Description

The NORTON 69014192293 is a Type 11V9 resinoid-bond diamond grinding wheel engineered for precision tool grinding and sharpening applications. It carries a 150-grit rating with a Very Fine grade, using Synthetic Diamond (SD) abrasive at 100 concentration. The wheel measures 3 inches in diameter with an overall thickness of 1.25 inches and a 0.75-inch hole bore. A 0.0625-inch superabrasive depth and a 0.375-inch face width deliver a focused cutting surface suited for carbide, ceramic, and hardened-steel tooling. Licensed trades and skilled toolroom machinists are the primary installers of this wheel.

This wheel is suited for bench grinder and surface grinder applications requiring a fine, controlled material removal rate. The Type 11V9 profile, combined with a 70-degree face angle, makes it effective for grinding relief angles on drills, end mills, and carbide-tipped cutting tools. It supports both wet and dry operation, giving shops the flexibility to use coolant for heat management or run dry where coolant is impractical. The SD150-R100B99-1/16 specification confirms the bond grade and abrasive depth for shops that need to match exact toolroom standards.

Key Features

• Synthetic Diamond abrasive at 100 concentration for consistent stock removal on carbide and ceramic tooling
• Type 11V9 profile with 70-degree face angle suited for relief and clearance grinding
• 150 grit Very Fine grade produces smooth ground surfaces and tight dimensional tolerances
• Resinoid bond offers controlled wear and resistance to loading during extended grinding cycles
• Supports wet and dry operation for flexible shop use
• 0.0625-inch superabrasive depth maximizes usable wheel life relative to wheel diameter

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for bench and tool grinders accepting a 3-inch diameter wheel with a 0.75-inch arbor bore.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified toolroom machinist or trained grinding equipment operator. Always power down and lock out the grinder before mounting or removing the wheel, and confirm that the machine spindle speed does not exceed the wheel's rated maximum RPM. Inspect the wheel for cracks or chips before each use and never force the arbor bore. When operating wet, verify that the coolant supply is flowing before engaging the wheel with the workpiece.
