A new high penetration replaceable insert drilling system has been launched in the UK and Europe by AMEC, which uses innovative helical insert geometry to give significantly faster penetration and increased productivity compared to similar products and solid carbide drills.
The GEN3SYS® system has been developed by the company for use with both ferrous and non ferrous materials to provide high metal removal rates, increased hole accuracy and true position, as well as high quality finish when drilling hole diameters from 12 mm to 22 mm metric or 0.4844" to 0.8594" imperial in 0.0156" increments
Using a unique patented helical geometry with high axial and radial rakes, GEN3SYS® insert profile has also been designed to provide optimum chip forming with elastic materials, such as stainless steels and alloys, without compromising chip control on other materials.
Two substrates, C1/K35 and C2/K20. and four different coating options are available within the system including as standard AMEC's new AM200® PVD coating, which ensures performance, wear and temperature resistance is maintained across a range of materials.
The GEN3SYS® system also includes a range of dedicated straight or helical fluted tool holders, which include through coolant ports to assist with chip removal and provide effective coolant delivery to the cutting edge. To ensure precise registration and absolute repeatability between tip changes, the insert location slots in all GEN3SYS® holders are precision ground, which also increases tool rigidity.
Rodney Crawford, Managing Director of Allied Maxcut, explained: "Our objective in developing GEN3SYS® was to create a drilling system that could deliver the best penetration and productivity within the 12 to 22 mm range, which accounts for around 20% of the market. Our new system not only achieves this but also provides a range of additional benefits in terms of accuracy, repeatability and finish, as well enhancing our already the scope of our already successful drilling range, which runs from 9.5mm to 114mm."
"Given that productivity improvement is primarily about the speed of manufacture, GEN3SYS®, enables us to offer significant production time and cost reduction over existing technologies, as well as giving high repeatability, which cannot be achieved with solid carbide tipped tools due to wear and re-setting," he added.
