Troubleshooting — Cutting Tools Outlet Guides

A tap drill that is too small increases torque; one that is too large reduces thread engagement.

Rough threads can be caused by a dull tap, unstable setup, poor chip evacuation or incorrect cutting conditions.

Tap breakage often comes from a wrong tap-drill size, misalignment, chip packing, excessive torque or poor lubrication.

Drill walking is usually a starting, alignment or point-geometry problem rather than a simple diameter problem.

Overheating usually comes from speed, pressure, dull edges, poor chip removal or insufficient lubrication.

Extractors are brittle and can snap when the pilot hole is too small, torque is excessive or the fastener is not centered.

A die can start crooked when the rod end is not chamfered, the die is not square or the setup is unstable.

Leaks may come from the wrong pipe standard, insufficient engagement, damaged threads or poor cleaning.

Breakage often follows excessive engagement, a weak setup, wrong tool geometry or chip evacuation problems.

End mill chatter is influenced by rigidity, overhang, flute count, radial engagement and cutting conditions.

Vibration often comes from excessive overhang, a bent shank, high side pressure or unstable workholding.

Aluminum can pack into a burr when the cut, speed, edge condition or lubrication is not suited to non-ferrous material.
