The Forney Industries 72386 is a high speed mandrel kit designed for use with high speed cutting wheels. Each kit includes mandrels that accommodate both 1/4 inch and 3/8 inch arbor holes, making it a versatile option for shops and field technicians who work with multiple wheel sizes. The kit contains 10 units per package, reducing the need for frequent reordering on high-volume jobs. This type of accessory is a standard component in metalworking, fabrication, and general cutting setups where rotary tools are used at high RPM.
This mandrel kit is suited for trade and industrial applications where high speed cutting wheels are mounted to rotary tools or die grinders. It is commonly used by fabricators, welders, and maintenance technicians who need reliable arbor compatibility across wheel sizes without switching tooling setups. The dual arbor hole sizing makes it practical for shops that stock multiple cutting wheel diameters.
Designed for use with high speed cutting wheels that feature 1/4 inch or 3/8 inch arbor holes, as specified by the manufacturer.
Installation should be performed by a qualified technician familiar with rotary tool and die grinder accessories. Ensure the rotary tool or grinder is fully powered down and unplugged before mounting or removing mandrels. Verify that the mandrel is securely tightened before operating at high speed, and confirm the cutting wheel's rated RPM meets or exceeds the tool's maximum RPM. Follow applicable ANSI safety standards for abrasive wheel mounting and operation.
