Following the successful launch of its corner rounding cutting tools, Nine9 has experienced remarkable demand and growing requests for extended size options. In response, the market-leading manufacturer has expanded its range to meet these needs, introducing small diameter rounding tools that push the boundaries of precision and performance.
Meeting the Demand for Micro Precision
Previously, Nine9’s corner rounding tools, available in the UK through Advanced Carbide Tooling (ACT), were offered in sizes ranging from 1mm to 6mm in 0.5mm increments. However, with the rise of micro-manufacturing and increasing demands for impeccable precision, Nine9 has now expanded its offerings. The new range includes diameters from 0.5mm to 1mm in ultra-fine increments of 0.01mm—smaller and more precise than anything available from competitors. This development addresses the needs of industries where even the slightest variations in size can impact product quality and performance.
Exceptional Performance and Extended Tool Life
The cornerstone of Nine9’s small diameter rounding tools is their P35 carbide insert, which is coated with titanium nitride (TiN). This ensures superior performance and extended tool life, making these tools ideal for a wide variety of materials, including carbon steel, alloy steel, stainless steel, high alloy and hardened steels, cast iron, aluminium and its alloys, as well as non-ferrous metals like brass, copper, and bronze.
With up to four cutting edges per insert, these tools offer cost efficiency by reducing the need for frequent insert replacements. In addition to their primary role in rounding, these versatile inserts are also suitable for both front and back chamfering operations, helping manufacturers streamline processes and minimize tooling inventory.
Uncompromising Rigidity and Robustness
Despite their small size, the inserts in the Corner Rounding Series are built for durability. Each insert is 4mm thick, providing the rigidity required to maintain accuracy and deliver smooth surface finishes across a wide range of materials. The precision-ground inserts ensure high positional accuracy in the insert seat, enhancing repeatability and maintaining exacting standards, even during tool changes.
Versatile Toolholders for a Range of Applications
The toolholders in Nine9’s Corner Rounding Series are available in shank diameters from 6mm to 25mm, with reach lengths of up to 150mm. Whether your application requires extended reach or increased rigidity, Nine9 offers solutions that guarantee high-quality surface finishes. End users can choose toolholders with either one or four insert pockets, depending on their specific application needs.
Manufactured from high-quality tool steel, these toolholders provide exceptional rigidity, further boosting tool life, accuracy, and surface finish quality.
