Regular Drill-out Extractors
They come in 4 sizes 1/4 inch (M6), 5 /16 inch (M8), 3/8 inch (M12) and 1/2 inch (M12).
The Drill-out ® is a drill bit AND extractor in one and is engineered with a Winslow self-centering tip.
Each tool is specially designed to drill into rough surfaces that are caused when bolts break.
The Drill-out ® tip not only gives you complete control-it allows you to obtain a perfectly centered hole without the tip walking or wandering.
The most unique feature of the Drill-out®'s tip is its left hand cutting edge.
This feature helps to loosen and sometimes even turn the bolt out during drilling.
