OVERVIEW

Precision Collet for Walter Straight-Mate Grinders

The Walter 48-M-615 1/4" Collet is a critical component designed exclusively for the Walter Straight-Mate line of straight grinders (die grinders). Engineered with the same commitment to quality as the power tools themselves, this collet ensures that your mounted points, carbide burrs, and other 1/4" shank abrasives are held securely and concentrically during operation.

In industrial environments, runout (wobble) in high-speed grinding applications can lead to poor surface finishes, premature abrasive wear, and increased operator fatigue due to vibration. This genuine Walter collet is precision-machined from high-grade steel to minimize runout, providing a smooth, stable rotation even at maximum RPM. It is an essential replacement part for maintenance and repair operations (MRO) to keep your Walter tools performing at their peak efficiency.

Whether you are replacing a worn-out collet or configuring a tool for a specific shank size, the 48-M-615 offers the perfect fit. Its robust construction resists deformation under tightening torque, ensuring a long service life in demanding metalworking fabrication shops. Trust genuine Walter accessories to maintain the safety and performance standards of your equipment.

FAQ

This collet is designed specifically for Walter Straight-Mate straight grinders (die grinders).

It accepts standard 1/4-inch (6.35mm) shanks, which is the most common size for die grinder accessories.

Yes, this is an OEM (Original Equipment Manufacturer) part from Walter Surface Technologies.

Worn collets can cause accessory slippage and increased vibration (runout), which damages the workpiece and reduces tool life.

No, 1/4" (6.35mm) and 6mm are slightly different. You should use the specific metric collet for 6mm shanks to ensure safety.

Typically, the part number 48-M-615 refers to the collet insert itself. The nut is usually a separate part unless specified as a kit.

It is made of hardened steel to resist wear and maintain tension over time.

Unscrew the collet nut, remove the old collet, insert the new 48-M-615 into the spindle, and re-tighten the nut loosely before inserting an accessory.
