NTK Fits a Square Peg in a Round Hole

Added to MTDCNC by NTK Cutting Tools on 15 February 2016

Intricate machining of square and hexagonal holes on sliding head turning centres has now been simplified by NTK with the arrival of its new Shaper Duo series of cutting tools. As an extension of NTK's Stick Duo range of solid carbide boring and turning products, the new Shaper Duo has been introduced to reduce the machining and set-up time when machining precise and intricate hole forms.

The Shaper Duo has been introduced as an innovative new solution 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 renowned line of Stick Duo tool holders, which reduces costs, set-up times and inventory for the end user. The Shaper Duo is offered in two geometry types, one for machining square holes and another for processing hexagonal holes or forms.

The innovative 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. The Shaper Duo achieves remarkable precision and tool life whilst obtaining outstanding surface finishes.
