The big Daddy is the most versatile and powerful marson brand hand riveter, taking the hard work out of setting larger diameter blind rivets. Its extra long handles provide excellent leverage and permit working a foot beyond natural reach. Other features include a patented bearing design, self-adjusting two piece jaws and single unit body construction with a steel insert to provide stronger threads for the nosepieces included. In addition, the big Daddy features a double gear reduction system which easily sets from 1/8 to 1/4 in Dia Klik-Fast rivets in all alloys, including 1/4 in Klik-Split and 3/16 in and 1/4 in Klik-Lock rivets. And a one piece collet case eliminates the need to adjust the tool when changing rivet diameters. The big Daddy model M39031 comes with 5/32 in, 3/16 in and 1/4 in nosepieces which are stored in the body. Weight 3.75 lb.
