GoHelper Portable Drill Guide

6061 aluminum alloy, CNC-machined and hard-anodized, 0°–60° adjustable angle with quick-release locking pins, depth stop collar, etched crosshair alignment grid, V-groove for round stock up to 3" diameter, 1/2" chuck fits 3/8" and 1/2" drills, drills up to 6.7" deep with the spring removed.

Genuinely feature-rich for the category — the etched crosshair grid and dual centering pins are real precision aids, not marketing language, and the aluminum construction is a meaningful durability upgrade over many plastic-bodied competitors.
