Chicago-Latrobe 11167 Aircraft Extension Drill
The Chicago-Latrobe 11167 is a new NAS-type aircraft extension drill built from high-speed steel with a black oxide finish. It features a #43 wire gauge size and a 135-degree split point designed for precision drilling tasks. The tool offers a maximum drilling depth of 1 1/4 inches.
Suited for machinists drilling deep.
This drill suits professionals performing high-performance machining on wire gauge #43 holes requiring extended reach. It is not for buyers needing larger diameter bits or different point angles for soft materials. Users requiring standard jobber length drills should look elsewhere.
Straightforward use in compatible drill chucks
Installation requires securing the straight shank into a standard drill chuck or collet matched to the wire gauge size. The split point design helps reduce walking on hard surfaces during initial contact. Problems typically arise from excessive speed or feed rates causing premature wear or breakage.
