Purpose and User

The Mayhew 22012 Line Punch marks straight lines on metal surfaces. Its 10 in. length and 3/16 in. tip suit layout and fabrication work. The 1/2 in. hex shank accepts extension bars for powered or machine-driven use. Steel construction provides the durability expected in professional shops.

Sustained Use Behaviour

The steel body resists deformation during repeated striking or continuous machine operation. The fixed tip geometry maintains consistent line width without mushrooming under load. The hex shank prevents rotational slip when driven by an impact tool or held in a chuck. Weight of 0.47 lb keeps the tool stable without causing rapid operator fatigue.

Thermals Noise and Power

Hand operation produces negligible heat and no audible noise beyond the strike itself. When mounted on a powered extension, the tool adds no electrical draw and generates only frictional warmth at the contact point. No cooling, lubrication or external power supply is required for normal use.

Questions about this item

How much heat or vibration does the 10 in. line punch produce during extended use?

As a hand-operated steel punch it generates no heat or vibration of its own; any warmth comes only from the workpiece being marked.

What must I already own to drive the 1/2 in. hex shank with a power tool?

An impact driver or drill with a 1/2 in. hex socket or adapter is required to engage the shank.

Will the 3/16 in. tip mark softer metals like aluminium without damaging them?

Yes, the hardened steel tip cleanly scribes aluminium, brass and mild steel without mushrooming.
