The Solo Drill Holster is designed to hold a range of drills, drivers and Screwgun. The interior is lined with tough Diamondskin to give you a quick draw, but we added a retention strap to prevent accidental discharge. There are 7 bit slots plus 5 other slots that can be used for bits or as attachment points. The Solo works for left, right or center carry and accepts a left or right side hammer holster.
