Key Features: Adjusts current setting potentiometers on stepper drivers Non-Conducting Tip Long lasting, good quality ceramic tip These are for adjusting those little current setti ng potentiometers on stepper drivers. The non-conducting tip means that accidentally poking other components, pins, or traces won't damage or interfere with the stepper driver. Using metal tipped screwdrivers while the driver is powered on can cause damage to the driver or even the controller board. Additionally using a metal tipped driver often introduces electrical noise during the adjustment as the metal driver acts as a small antenna making precise adjustment hard.Item Specifics1 - Ceramic DriverShould not be used as a general purpose screwdriverNot Recommended for applying larger torques Show more
