DeHoff Drilling Machine Used for Helicopter Manufacturing
April 1, 2025
The DeHoff 25108 is a BTA drilling machine used to manufacture helicopter tail rotor drive shafts. The shaft begins as a solid piece of high-strength alloy steel and is drilled in a single pass using the DeHoff machine. This results in a significant weight reduction for the finished drive shaft.
The DeHoff 25108 has a BTA drilling diameter capacity of 2.5" (63.5 mm) and a maximum drilling depth of 108" (2,743 mm). It features a 20 HP AC spindle motor and four-speed gearbox to provide versatile drilling performance. The workpiece is counter-rotated in the opposite direction of the drill rotation, which improves the accuracy of the drilled hole.
DeHoff BTA drilling machines are designed and manufactured by Kays Engineering in Marshall, MO.
