RIFLING BUTTONS

The rifling buttons are harder to make than the reaming or swaging buttons. They are made the same
except for the grooves are cut in the button (Lands). For example a six-groove button, the included angle
on the diamond wheel forming the groove must be no more than 60 degrees, so the sides of the
Impressed groove in the rifle barrel are not undercut.

The plane of revolution of the diamond wheel in the grinding process must lie precisely along the helix of
the groove in the button.

BUTTON SIZES

The diamond wheels used for grinding the carbide buttons can be purchase from Ash and Co, or
Wholesale Tool. If you have an indexing attachment for your mill, you will be able to make your own
buttons. If you desire to buy the first ones, they can be purchase from Danjon Corp.
