Cratex 53 C Surface Grinding Wheel 5/8 in Silicon Carbide

Product Description

The CRATEX 53 C is a small-diameter surface grinding wheel engineered for precision material removal on delicate and intricate workpieces. It measures 5/8 inches in diameter, 3/32 inches thick, with a 1/16-inch center hole. The wheel uses a silicon carbide abrasive grain bonded in a rubber matrix, which provides a degree of flexibility and surface conformance that rigid vitrified wheels cannot offer. Rated to 25000 RPM, it is suited for high-speed rotary tools and spindles common in fine finishing and deburring applications. The coarse grade designation makes it effective for aggressive stock removal at small scale.

This wheel is applied across precision and light-duty grinding tasks where part geometry or material sensitivity demands a controlled, fine-profile tool. Documented applications include aerospace components, control mechanisms, dies, electronic parts, instruments, jewelry, light castings, molds, plastic articles, and super sensitive scientific devices. It is equally at home in a toolroom, a jeweler's bench, or an electronics assembly environment where standard bench grinders are too aggressive or too large for the work at hand.

Key Features

• Silicon carbide abrasive for effective cutting on non-ferrous metals, ceramics, and plastics
• Rubber bond construction provides slight flexibility, reducing chatter and surface damage on delicate parts
• Coarse grade for efficient stock removal in precision small-scale applications
• 25000 RPM maximum speed rating compatible with high-speed rotary tools and die grinders
• Compact 5/8-inch diameter fits tight clearances and intricate geometries
• Green wheel color consistent with silicon carbide compound identification
• No recess design for straightforward mounting and face grinding use

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.

Installation Notes

Installation should be performed by a qualified toolroom technician or machinist familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and disconnect the rotary tool or spindle before mounting or removing the wheel. Verify the tool spindle speed does not exceed the 25000 RPM rating marked for this wheel. Inspect the wheel for cracks or chips before each use and do not operate a damaged wheel.
