30B047 - Walter 1/8-Inch Replacement Collet for 6141/6145 Grinders

Precision Replacement Collet for Walter Grinders

The Walter 1/8 In Collet (SKU: 30B047) is a critical component designed to maintain the high-performance standards of Walter straight grinders. Specifically engineered for compatibility with models 6141, 6145, and 6145D, this collet ensures that 1/8-inch shank accessories are held with absolute security during operation. In precision grinding and finishing applications, runout—the amount a tool wobbles as it spins—is a primary concern. A worn or inferior collet can introduce significant runout, leading to premature wear of carbide burrs, mounted points, and the grinder's own bearings.

Manufactured from high-grade steel and machined to tight tolerances, this OEM replacement part restores the concentricity of your power tool. It provides a uniform grip around the accessory shank, maximizing power transfer and minimizing vibration. This is essential not only for the quality of the finish but also for operator safety, as a slipping accessory at high RPMs poses a significant hazard. Whether you are performing delicate die grinding or general metal preparation, ensuring your collet is in prime condition is necessary for achieving consistent results.

Regular inspection of the collet system is recommended for all industrial grinding operations. If you detect signs of wear, such as scoring inside the collet bore or difficulty tightening the nut, replacing the unit with this genuine Walter 30B047 collet is the most effective maintenance step. It integrates seamlessly with the existing collet nut and spindle assembly of the specified Walter tools, ensuring a factory-perfect fit and function.
