How do I avoid the over-reamed pipe flange fracture

High-torque reamers and deburring cones will bite and kick back if forced into heavy metal burrs too quickly. Maintain a firm, two-handed grip on the tool body, position the cone perpendicular to the rim track, run the motor at half-speed, and use light,.

Plain-English answer

You are opening up a round field cut on a heavy 14-gauge black iron smoke stack using a high-torque electric pipe reamer tool. You force the reamer head into the pipe rim with intense structural weight. The tool catches an internal burr, kicks back violently, and cracks the aluminum casing housing of the motor frame.

High-torque reamers and deburring cones will bite and kick back if forced into heavy metal burrs too quickly. Maintain a firm, two-handed grip on the tool body, position the cone perpendicular to the rim track, run the motor at half-speed, and use light,. 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 cracked the tool frame because you rammed the reamer straight into a heavy burr. Keep a two-handed grip on that high-torque tool, drop the motor speed down, and glide the cone gradual across the steel.

Verify before acting
