Mayhew 1/2in Cape Chisel

The Mayhew 10505 is a half-round nose cape chisel forged from steel and finished in black oxide. Its 55 to 57 HRC tip hardness is tuned for cutting semi-circular grooves such as oil ways in bearings. The plain steel grip has no striking cap and no tether point. It is a new hand tool for metalwork tasks that need a curved channel.

Metalworkers cutting bearing oil ways

The chisel suits machinists and maintenance technicians who need a dedicated half-round profile for bearing work. Buyers who want a striking cap, a tether-ready hole or a handled grip should look at something else. The plain steel shank also means it is not intended for non-sparking environments.

55 to 57 HRC blade tip hardness

That hardness range decides whether the tool holds its edge in the alloy you are cutting. If your application demands a softer or harder tip, this chisel will not match the requirement.

Questions about this item

How much heat does the 10505 chisel generate when struck repeatedly?

The tool itself produces no heat; only the workpiece warms from friction and impact energy.

What must I already own to use this half-round nose chisel?

A suitable hammer and a stable metal workpiece are required; the chisel has no handle and no striking cap.

Will the 55 to 57 HRC tip hold up against older mild-steel bearings?

Yes, the hardened tip is significantly harder than mild steel and will cut semi-circular grooves cleanly.
