The machining of challenging materials is now simpler thanks to the expansion of the Union Tool range of CZS cutting tools. Available in the UK from Rainford Precision, the series of solid-carbide end mills from Union now covers new diameters. The range is currently available with a time-limited 50% discount (until end of January).

Union CZS end mills incorporate a geometry design that combines with a micro-grain carbide substrate and a tough UT coating to provide manufacturers with high performance levels. CZS end mills are suitable for machining everything from carbon, alloy and pre-hardened steels to 55 HRc, as well as aluminium, titanium, heat resistant alloys, copper and cast iron, making the CZS a high performing all-rounder on most types of engineering materials.

The new CZS end mills have a 40° high-helix angle for swarf evacuation that combines with a variable pitch helix which reduces harmonic effects and vibration when undertaking high-speed milling tasks. With a flat land as part of the patented tip geometry, the CZS series is suitable for drilling, milling, side milling, slotting, pocketing and trochoidal cutting operations, reducing the requirement for multiple cutting tools and excessive inventory. Furthermore, the edge geometry and high-quality carbide grade make the CZS suitable for vertical milling with high resistance to edge chipping, while the low-friction coating enhances chip evacuation and improves wear resistance.

The four-flute square end tools cover new diameter ranges that make the series available from 1 to 6 mm diameter in 0.1 mm increments, and 6 to 12 mm in 0.5mm increments. Rainford reports that 13, 16 and 20 mm diameter end mills are also available.
