Quickgrind’s high feed Spectre range is suitable for rough machining operations such as slotting, pocket milling and contour machining. Indeed, the end-mills can even be used for pocketing with high length-over-diameter ratios and intricate features, says the company.

Spectre three-flute end-mills are based on a coated carbide substrate, novel edge geometry and neck-relieved shanks. Developed to withstand high cutting forces, the cutters are recommended for extended reach in deep cavity machining operations. Further applications where machine shops will benefit from the use of Spectre end-mills include plunging and helical ramping.

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

Spectre 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 50 HRC). The cutters are available in 3, 6, 8, 10 and 12 mm diameters. Long series versions can be acquired in 6 and 8 mm diameters, with short series types available in 8 and 12 mm diameters.
