The new Spectre series of solid-carbide end mills is being launched by Quickgrind so that machine shops are able to introduce significantly increased speeds and feed rates into their milling operations. By reducing depth of cut and increasing feed rate by up to six times that of conventional end mills, manufacturers can achieve highly reduced machining times with greatly improved productivity and material removal rates.

Quickgrind’s high-feed Spectre range is ideal for rough-machining operations such as slotting, pocket milling and contour machining. Indeed, the end mills are perfect for pocketing with high length-over-diameter ratios and intricate features. Spectre three-flute end mills are based on a tough carbide substrate design featuring a superior coating, unique edge geometry and neck-relieved shanks. As a result, strong, stable and efficient machining is assured, while the coating aids chip flow and provides high resistance to wear.

Developed to withstand extreme cutting forces, Spectre high-performance end mills are recommended for extended reach in deep cavity machining operations. With this in mind, the tools should be considered for use wherever the deployment of conventional small diameter, long series cutters (or extra-long end mills) is fraught with danger. Further applications where machine shops will benefit from the use of Quickgrind Spectre end mills include plunging and helical ramping.

To demonstrate the performance levels available, Quickgrind says that a 12mm diameter Spectre cutter will be able to mill materials such as carbon steel, alloy steel or cast iron (at 0.7mm depth of cut) at cutting speeds of up to 180m/min and feed per tooth of up to 0.6, depending on the specific application.

Spectre series end mills are also suitable for machining materials such as stainless steel (including Duplex and Super Duplex), Inconel, titanium, tool steel and hardened steel (up to HRC50). The cutters are available in 3, 6, 8, 10 and 12mm diameters. Long series versions can be acquired in 6 and 8mm diameters, with short series types available in 8 and 12mm diameters.
