Mandrel assembly for cut-off wheels

The Pferd 69027 mandrel assembly fits a 3/8 in hole and accepts cut-off wheels in machine-shop applications. Its 1/4 in shank and 1/4 in pilot diameter suit standard tool holders for general metalworking tasks. The unit is supplied new and ready for workshop use. It addresses the need for a secure wheel-mounting solution in fabrication and maintenance work.

Thermals noise and power draw in normal use

The assembly runs at up to 30,000 RPM, so heat and vibration depend on the wheel used and the workpiece material. No motor or active cooling is present; the operator controls feed rate to manage temperature. Noise level varies with wheel type and cutting conditions. Power draw is determined by the driving tool, not by the mandrel itself.

Questions about this item

How do I install the mandrel assembly with a 1/4 in shank and 3/8 in pilot, and what step is often missed?

Insert the 1/4 in shank into the tool chuck, seat the 3/8 in pilot through the wheel, then tighten the 3/4 in thread securely; the step often missed is fully engaging the 2 1/8 in pilot length before tightening.

What maintenance or replacement will the HAWA mandrel assembly need during its service life?

Inspect the 1/4 in pilot and 3/4 in threads for wear or damage before each use; replace the assembly if the pilot shows deformation or the threads no longer hold the cut-off wheel firmly at 30,000 RPM.
