TYPES AND USES
CIRCLE GASKET CUTTER
HOLLOW GASKET CUTTER
The compass-style circle gasket cutter cuts gaskets
from 4-inch diameters through 20-inch diameters. It cuts
leather, paper, plastic, rubber, sheet lead, or thin wood.
It has an aluminum frame with a graduated scale, steel
pivot pin, and tempered tool steel knives. It requires a
knurled thumb screw adjustment to change diameters.
BIT BRACE CIRCLE GASKET CUTTER
The bit brace circle gasket cutter adjusts from 1 to 5-1/2
inches in diameter. It cuts metal, plastic, wood,
hardwood and other materials. It has a tapered square
shank to fit a bit brace. It comes with a 3/16-inch tool
steel bit, 1/4-inch pilot drill, and a hex wrench for easy
adjustment.
The hollow gasket cutter is also known as a hollow
punch. It is extremely serviceable for cutting soft mate-
rials. It comes in a set with a mandrel. The sizes are 1/4,
5/16, 3/8, 7/16, 1/2, 9/16, and 5/8 inch. The set will
withstand unlimited use if a hardwood block is used
under the gasket material when cutting gaskets. They
are not designed for cutting metal or cutting against a
hard surface. Other individual hollow gasket cutters are
also available.
