Yokomo YT-SR3W Works Wrench 3.0mm Straight Reamer  [YT-SR3W]

3.0mm straight reamer for RC

A compact straight reamer designed for RC-scale suspension pins, the Yokomo YT-SR3W is intended to pass cleanly through 3.0mm suspension pin holes to restore alignment and remove burrs that interfere with smooth pivoting. The cutting element is a carbide bit and the shank includes an aluminum grip shaped for hand work, delivering a balance of cutting durability and handling comfort during setup and routine maintenance.

In practice this tool is used when fitting suspension arms and checking pin fit: run the reamer along the pin axis through the hole to true the bore, then check for free moving pins and predictable arm movement. Because it is lightweight and made for manual operation, it reduces hand fatigue during repeated hole cleanup tasks and helps maintain consistent suspension response while tuning.
