Norton 66252838309 Type 2 Grinding Wheel 6 in 60 Grit

Product Description

The NORTON 66252838309 is a Type 2 aluminum oxide grinding wheel designed for tool cutting and grinding operations. It measures 6 inches in diameter with a 1-inch face width and accepts a 1-1/4-inch arbor hole. The wheel is vitrified-bonded, rated at J hardness (medium grade), and carries a 60-grit abrasive specification of 32A60-JVBE. Maximum operating speed is 3,600 RPM. The gray, non-porous wheel suits precision grinding tasks where consistent stock removal and controlled wheel wear are required. Installation and operation are appropriate for qualified grinding machine operators following ANSI B11.9 guidelines.

This wheel is suited for bench grinder and pedestal grinder applications in machine shops, maintenance departments, and tool rooms. The 60-grit, medium-hardness combination makes it effective for general-purpose tool grinding, reshaping, and sharpening of high-speed steel and similar tooling. Its Type 2 cylinder form provides a broad grinding face for flat or surface grinding contact. The vitrified bond delivers consistent performance across a range of ferrous materials.

Key Features

• Type 2 cylinder wheel form with a 1-inch face width for broad surface contact
• Aluminum oxide abrasive, specification 32A60-JVBE, for general-purpose ferrous grinding
• Vitrified bond for consistent hardness and dimensional stability during use
• J hardness code (medium grade) balances wheel life and cutting action
• 60-grit abrasive provides medium stock removal and a moderate surface finish
• 3,600 RPM maximum operating speed — verify machine speed before mounting

Compatibility

Designed as an OEM-style replacement or standard replacement grinding wheel for bench grinders and pedestal grinders accepting a 6-inch diameter, Type 2 wheel with a 1-1/4-inch arbor bore.

Installation Notes

Grinding wheel mounting and dressing must be performed by a qualified operator following ANSI B11.9 and applicable OSHA standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 3,600 RPM maximum speed rating. A properly rated wheel guard must remain in place during operation.
