AeroTech 54mm Delay Drilling Tool - 54RDDT

The 0.1mm increments on the drilling depth gauge give me the precision I needed for fine-tuning ejection charges. It fits the 54mm cases perfectly with no slop, and the carbide bit is still sharp after five uses.

Finally, a tool that makes adjusting 54mm delays clean and repeatable — the machined hole depth is precise every time. I used it for my last two flights and got the exact delay I wanted without any guesswork. Makes drilling into the delay element feel solid and controlled.

The machined fit on the delay element was spot-on, making the adjustment process feel precise and repeatable. I drilled three motors in a row and each one hit the same delay time perfectly.
