Norton 61463650275 Surface Grinding Segment 30 Grit

Product Description

The NORTON 61463650275 is a vitrified-bond aluminum oxide surface grinding segment engineered for precision stock removal on horizontal and vertical spindle surface grinders. Measuring 5 inches wide, 6 inches high, and 1-1/2 inches thick, this segment delivers consistent cutting action across its full face. At 30 grit (Very Coarse grade), it is built for aggressive material removal applications where rapid stock reduction takes priority over fine surface finish. The vitrified bond provides an open, porous structure that resists loading and maintains free-cutting performance across extended use cycles. Specification code 86A30-G12VBEP identifies the exact formulation for reorder and cross-reference. Grinding wheel mechanics and abrasive product specialists handle installation and dressing.

This segment is suited for surface grinding operations in industrial maintenance, tool and die, and production grinding environments. It is designed for use on Hanchett, Mattison, and Norton surface grinders where segments of this profile are the specified consumable. The 30-grit, Very Coarse grade is appropriate for initial passes on castings, hardened steel, and similar ferrous workpieces where heavy stock removal is needed before finish grinding. Blueprint number ME20579 provides the original equipment reference for shops working from machine documentation.

Key Features

• Aluminum oxide abrasive material for reliable performance on ferrous metals
• 30 grit, Very Coarse grade for high material removal rates
• Vitrified bond construction resists loading and maintains open cutting action
• Porous grain structure (grain structure 12) promotes coolant flow and heat dissipation
• Hardness Code G provides a relatively soft grade that releases dull grains to expose fresh abrasive
• Blueprint number ME20579 and spec code 86A30-G12VBEP support direct OEM cross-reference

Compatibility

Designed for use on Hanchett, Mattison, and Norton surface grinders that accept segments measuring 5 inches wide, 6 inches high, and 1-1/2 inches thick, per blueprint ME20579.

Installation Notes

Surface grinding segments are installed and replaced by qualified grinding machine operators or maintenance technicians familiar with abrasive product handling standards. Always power down and lock out the grinder before removing or seating segments. Inspect the segment holder and mounting surfaces for damage or debris before installation. Follow the machine manufacturer's torque and seating procedures, and ring-test or visually inspect segments per ANSI B7.1 before placing the machine back in service.
