How to use

Select the appropriate drill bit or screwdriver bit for the task and insert it into a compatible 1/4" hex quick-change holder or drill chuck.

For fastening operations, fit the correct Phillips or Pozidriv bit onto the hex adapter and apply steady, controlled torque to avoid cam-out or damage to fasteners.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. When drilling metal, consider a lubricant or cutting oil and moderate speeds to reduce heat and wear. Store bits in a dedicated case or organizer to preserve concentricity and prevent damage.
