The Shaper Duo has been introduced for use on the sub-spindle tooling platens of small turning centres and sliding head lathes. The PVD coated solid carbide Shaper Duo tooling inserts are compatible with NTK's line of Stick Duo tool holders, which reduces costs, set-up times and inventory for the user. The Shaper Duo is offered in two geometry types, one for machining square holes and another for processing hexagonal holes or forms. 

The new hexagonal Shaper Duo line is available with a tool diameter of 2, 3, 4, 5, 6 or 8mm to correspond with the respective Stick Duo toolholder. The Shaper Duo has two cutting edges on each tool that is available with an overall length of 50, 60, 70 or 80mm. The geometry on the hexagonal series has been manufactured with a base across flat dimension of 1.5, 2,3, 4, 5, 6 and 8mm, which means the tool will easily work within holes of these dimensions. Each of the respective 120 degree tools have an Across Flat 'AF' range of 1.4 to 2, 1.9 to 2.6, 2.4 to 3.6, 3.4 to 4.6, 4.4 to 6.2, 5.9 to 8.2 and 7.9 to 12.2mm. 

For machining square holes and forms, the 90 degree Shaper Duo is available with diameter dimensions the same as the hexagonal range with an Across Flat 'AF' range that includes sizes of 1.9 to 2.3, 2.2 to 2.6, 2.5 to 3.0, 2.9 to 3.7, 3.6 to 4.6, 4.5 to 5.4, 5.3 to 6.6 and 6.5 to 8.1mm. Benefits claimed for the Shaper Duo include a high degree of precision and outstanding surface finishes.
