Plunger Latch Step Drill for Screen Frames
This Prime-Line step drill is designed for installing aluminum screen plunger bolts into hollow frames. It drills two different diameter holes in a single pass, streamlining the installation process. The tool is constructed of hardened steel for durable, lasting usage on the job site.
Two Diameters in One Pass for Efficient Installation
The drill features a 1/8 inch diameter to penetrate both layers of the aluminum frame and a 7/32 inch bit for the top layer only. This design eliminates the need to swap bits during assembly. It works with standard power drills and requires only a few simple tools to operate effectively.
Replaces Separate Bits for Plunger Bolt Jobs
This single tool replaces the need for two separate drill bits when fitting plunger bolts, saving time on repetitive screen repairs. The step design is specific to this fastener type and frame material. It is not suited for general metal drilling tasks or thicker gauge materials beyond screen frames.
