Save Money and Become More Efficient the Diatip way

Published: 30/9, 2019

Jack Midhage is one of the legends of the Swedish concrete cutting industry. He founded one of the country's leading namesake diamond tool manufacturing and building machinery suppliers, and is well-known internationally for developing the mobile diamond segment-retipping device, Diatip.

Although Midhage passed away in 2005, his legacy still lives on. The Diatip system is sold worldwide from the Midhage Diatip AB company, which is run by his children, Carina and Morgan.

The Diatip system is a smart solution that enables concrete cutters to tip core drills themselves, rather than outsourcing the work or purchasing new bits. With the Diatip device, a sufficient stock of freshly retipped drill bits will always be available ready to work on new jobs right away. What's more, the retipping procedure is easy. In just minutes, the Diatip device revives a worn-out tip by cutting between the first rows of slots. The worn ring of diamonds falls off, and the surface is ready for brazing of new diamond segments. 

The Diatip series consists of four different models. The CD 7-28 Manual is the basic model and works without electricity to retie drillbits from 1.5 in to 27.5 in (38mm to 700mm). A hydraulic version of this machine is also available. The CD 600 Economy has the same functions as the basic model, but is easy to transport, allowing retipping of core bits up to 23.6 in (600 mm) even on the worksite. 

The most advanced model, the CD 7-28 Automatic, cuts off the worn end of the old core bit and makes indexed regulated slots completely automatically. The required number of segments, and the depth of the slots for the segments is then set, with the system equipped with a hydraulic motor for cutting and a PLC-controlled electrical motor for feeding. During the brazing process, rotation of the bit is regulated by a foot pedal, leaving both hands free for the silver rod and gas pistol. 

Besides the actual retipping machines, magnets to hold the new diamond segments are also produced and sold by Midhage Diatip. The company also sells silver and flux for the brazing as well as a number of accessories.
