Question

what kind of bit is this?

Explanation:

Identify the tool shape

The image shows a screwdriver insert bit with a flat tip that has a distinctive notch or cutout in the center, leaving two protruding prongs.

Match with standard bit types

A flat tip with a central notch is designed to drive security screws that have two corresponding holes. This specific design is commonly known as a spanner bit (also referred to as a snake-eyes, notched-flathead, or dual-prong bit).

Analyze the markings

The number "8" stamped on the hexagonal shank indicates the size of the spanner bit (a #8 spanner bit).
