Cratex 1358 M Rubberized Abrasive Cone Point Medium Grade

Product Description

The CRATEX 1358 M is a rubberized abrasive cone point designed for precision deburring, blending, and surface finishing on metal and other hard materials. The cone shape allows access to contoured surfaces, cavities, and inside radii where flat or cylindrical wheels cannot reach. At medium grade with a 90-grit silicon carbide abrasive matrix, it removes material efficiently while leaving a smooth, consistent finish. Rated to 20,000 RPM, this unmounted point is designed to be pressed onto a mandrel or arbor before use. It weighs 0.2 pounds and is intended for use by machinists, tool-and-die workers, and metalworking professionals.

The 1358 M suits bench-mounted or handheld rotary tool applications requiring controlled stock removal on ferrous and non-ferrous metals, ceramics, and composites. Its 1-inch maximum diameter and 1-3/4-inch length make it well suited for internal finishing work, weld blending in tight spaces, and edge preparation on machined components. The 1/4-inch arbor hole accepts standard mandrels common to die grinders and flexible shaft machines used in production and maintenance environments.

Key Features

• Cone profile provides access to contoured surfaces, grooves, and inside radii
• Silicon carbide abrasive matrix delivers consistent cut on hard metals and ceramics
• Medium grade (90 grit) balances material removal rate with surface finish quality
• 20,000 RPM maximum speed rating suits standard die grinder operation
• Unmounted design accepts standard 1/4-inch arbor mandrels
• Rubberized bond provides flexibility and resistance to loading during use

Compatibility

Designed for use with standard 1/4-inch arbor mandrels compatible with die grinders, flexible shaft machines, and rotary tool systems operating within the 20,000 RPM maximum speed rating.

Installation Notes

Installation is performed by pressing or threading the cone point onto a compatible mandrel sized for the 1/4-inch arbor hole. Ensure the mandrel and point are fully seated before operation. Verify that the tool spindle speed does not exceed the 20,000 RPM rating marked on the point. Wear appropriate eye protection and follow tool manufacturer guidelines for abrasive accessory mounting and use.
