Cratex 86-2 M Surface Grinding Wheel 1 in Rubber Bond

Product Description

The CRATEX 86-2 M is a rubber-bonded surface grinding wheel designed for precision material removal on delicate and fine-tolerance workpieces. Measuring 1 inch in diameter and 3/16 inch thick with a 1/8 inch arbor hole, this wheel suits bench grinders, rotary tools, and spindle-mounted setups where controlled stock removal and smooth surface finish are the priority. The rubber bond cushions the abrasive action, reducing the risk of burning or distorting sensitive parts. Rated to 25000 RPM, it handles high-speed tooling commonly used in detail and finishing work. Medium grade provides a balance between cut rate and surface quality.

This wheel is specified for precision grinding applications across aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices. It is well suited for shops and technicians working with tight tolerances on small or intricate parts where aggressive abrasives would cause damage. The compact 1 inch diameter allows access to confined areas and small bores that larger wheels cannot reach.

Key Features

• Rubber bond construction cushions abrasive contact, reducing heat transfer and surface burning on sensitive materials
• Medium grade abrasive balances material removal rate with smooth finish output
• 25000 RPM maximum speed rating supports high-speed rotary and spindle tooling
• 1 inch diameter and 3/16 inch thickness suit confined grinding paths and small-part work
• 1/8 inch arbor hole fits standard small-diameter mandrels and collet holders
• Brown wheel color consistent with standard CRATEX rubber-bonded abrasive identification

Compatibility

Designed for use with aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices as stated by the manufacturer. Fits rotary tools, bench grinders, and spindle setups accepting a 1/8 inch arbor.

Installation Notes

Mounting and operation of abrasive wheels should follow ANSI B7.1 safety standards and any applicable shop safety codes. Ensure the spindle or mandrel speed does not exceed the 25000 RPM rated maximum before mounting. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel. Eye protection and appropriate guarding are required during grinding operations.
