Apprentice answerHow do I avoid the smoking turbo-shear burnout (speed vs torque)
1st YearInspection, QA/QC, Finish & CloseoutField Reference
Mechanical shear drill attachments require high structural torque, not spinning speed. Shift your drill's gearbox down into Low Gear (Speed Setting 1) to maximize torque output and lower heat buildup. Keep the tool's throat parallel to the metal face and.

Plain-English answer
You attach a sheet metal Turbo-Shear drill attachment to a high-speed, lightweight 12V drill to cut a 16-gauge industrial line. You run the drill at full speed. Within 2 feet, the cutting blades get red hot, smoke, and stall out completely inside the metal joint.
Mechanical shear drill attachments require high structural torque, not spinning speed. Shift your drill's gearbox down into Low Gear (Speed Setting 1) to maximize torque output and lower heat buildup. Keep the tool's throat parallel to the metal face and. The likely recovery is to check the tool setup, correct the prep or technique if it is within your assignment, and bring the journeyman or foreman clean information before the work creates rework overhead.
Ask Foreman
You burned up the shear blades because you ran the drill in high speed. Flip the gearbox down into low gear for maximum torque, keep the blades upright, and let the tool bite at its own pace.
Verify before acting
