Norton 61463650279 Surface Grinding Segment 24 Grit

Product Description

The NORTON 61463650279 is a vitrified-bond surface grinding segment designed for heavy-duty stock removal on surface grinders. It measures 11-1/4 inches wide, 6 inches high, and 2-1/4 inches thick, making it suited for large-area passes on industrial surface grinding machines. The abrasive material is aluminum oxide with a 24 grit rating, placing it firmly in the very coarse range for aggressive cutting action. Hardness code E and grain structure 12 give the segment a soft, open bond that releases worn grains quickly and keeps the wheel free-cutting. At 12 pounds, this segment is built for sustained production grinding cycles.

This segment fits applications requiring rapid material removal from ferrous workpieces such as steel and cast iron. The porous, vitrified bond supports coolant flow through the wheel face, reducing heat buildup during extended grinding passes. It is referenced under Norton blueprint number ME30777 and specification code 86A24-E12VBEP, which allows direct cross-reference for shops ordering by blueprint or specification string. Typical users include tool-and-die shops, metal fabrication facilities, and industrial maintenance operations running segmented-wheel surface grinders.

Key Features

• Aluminum oxide abrasive — effective on ferrous metals including steel and cast iron
• 24 grit, very coarse grade for high-rate stock removal
• Vitrified bond with open, porous structure promotes coolant penetration and reduces glazing
• Hardness code E soft bond allows consistent self-dressing action under load
• Grain structure 12 supports free-cutting performance in production grinding cycles
• Blueprint number ME30777 and spec code 86A24-E12VBEP support direct OEM cross-reference

Compatibility

Designed for use in the Cortland application as specified by the manufacturer. Cross-references to Norton blueprint ME30777 and specification 86A24-E12VBEP for direct substitution in operations already using those callouts.

Installation Notes

Installation should be performed by a qualified grinding machine operator or industrial maintenance technician following the machine manufacturer's mounting instructions. Always power down and lock out the grinder before seating or removing grinding segments. Inspect the segment for cracks or chips before mounting — do not use a damaged segment. Consult ANSI B7.1 safety code requirements for proper wheel and segment handling in your facility.
