30B061 - Walter 1/4-Inch Shank Adaptor for 1/4-20 Threaded Accessories

Precision Adaptor for Industrial Abrasives

The Walter 1/4" Adaptor Mandrel (SKU: 30B061) is a specialized accessory designed to bridge the gap between threaded abrasive consumables and standard power tools. In the metalworking industry, flexibility is key, and having the ability to mount specific abrasive heads onto a die grinder or power drill can significantly enhance productivity. This mandrel is engineered to convert accessories featuring a 1/4"-20 male thread into a standard 1/4" round shaft, making them compatible with the collets found on most pneumatic and electric die grinders.

Constructed from high-grade steel, this adaptor is built to withstand the torque and rotational forces generated during grinding, deburring, and finishing operations. A precise fit is critical when spinning tools at high RPMs; a poorly made adapter can introduce runout, leading to vibration, poor surface finish, and potential safety hazards. Walter Surface Technologies is known for its commitment to quality, and this mandrel reflects that standard by ensuring concentricity and a secure hold. It allows operators to utilize a wider range of brushes, flap wheels, and specialty abrasives that may otherwise be restricted to specific mounting systems.

Integration into your existing toolset is seamless. Simply thread the abrasive product into the adaptor and insert the 1/4" shank into your tool's collet or chuck. This simple mechanism opens up new possibilities for reaching into tight corners, contouring irregular surfaces, and performing detailed surface preparation tasks. Whether you are working in a fabrication shop, a maintenance department, or a production line, having the right adapter can save time and reduce the need for multiple dedicated power tools.

Key Technical Benefits:

• Versatility: Instantly transforms threaded accessories for use in standard collets.
• Durability: Machined from robust steel to resist wear and deformation.
• Safety: Provides a stable and balanced connection to reduce operator fatigue caused by vibration.
• Compatibility: Fits any power tool accepting a 1/4" round shank.
