3M 7100139210 Cut-off Wheel 3 in 36 Grit 25465 Rpm

Product Description

The 3M 7100139210 is a Type 1 straight cut-off wheel engineered for fast, consistent metal cutting in demanding fabrication environments. Measuring 3 inches in diameter and 0.060 inches thick, this wheel uses 3M Precision Shaped Grain ceramic abrasive bonded with resin to deliver a high cut rate through stainless steel, carbon steel, cast iron, aluminum, soft metals, and other alloys. It carries a maximum operating speed of 25,465 RPM and meets ANSI B7.1 specifications. Reinforced construction adds structural integrity during high-speed operation. Metalworkers, pipefitters, and fabricators reach for this wheel when cycle time and wheel life both matter.

This cut-off wheel is suited for industrial and production environments where repeated cuts through pipe, tubing, and flat sheet stock are required. Common applications include weld removal, beveling, edge chamfering, and general metal cutting across shipbuilding, rail, and metal fabrication operations. The 3/8-24 threaded center hole allows mounting on standard cut-off wheel tools. The wheel is sold individually and requires a compatible cut-off tool and approved wheel guard for safe operation.

Key Features

• 3M Precision Shaped Grain continuously fractures to expose sharp cutting edges, reducing gouging and heat buildup
• Type 1 straight profile for standard cut-off applications on pipe, tube, and flat stock
• Resin bond construction rated to 25,465 RPM maximum operating speed
• Reinforced wheel meets ANSI B7.1 safety specifications
• 3/8-24 center hole thread for secure mounting on compatible tools
• Compatible with stainless steel, carbon steel, cast iron, aluminum, soft metals, and aerospace alloys

Compatibility

Designed for use on cut-off wheel tools accepting a 3-inch diameter, Type 1 wheel with a 3/8-24 threaded center hole; the power tool used must have a maximum operating speed equal to or less than 25,465 RPM, and must be fitted with an ANSI B7.1 approved guard.

Installation Notes

Installation and wheel changes should be performed by a qualified operator following the tool and abrasive manufacturer guidelines. Always power down and disconnect the tool from its power source before mounting or removing the wheel. Verify that the tool maximum RPM rating does not exceed the wheel maximum speed of 25,465 RPM before operation. Always use an approved wheel guard in accordance with ANSI B7.1 — never operate this wheel on an unguarded tool.
