Guhring Launches RF 100 AL Milling Line

3 November 2025

As ‘lightweighting’ components for e-mobility, aviation and transport industries need to be manufactured more efficiently, the requirement for advanced aluminium machining solutions has never been greater. Materials in the ISO-N group are becoming increasingly prevalent, and to support this, Guhring has now introduced the comprehensive RF 100 AL range of end mills.

This exciting new family of high-end solid carbide milling cutters available in diameters from 1 to 25mm has been designed to meet the exacting requirements of modern aluminium, non-ferrous metal and plastic machining. Complementing this exceptional new line is the new Guhring RF 100 AL Micro that sits at the micro end of the spectrum. Available in all popular diameter increments from 0.5 to 3.0mm with cutting lengths of 2.5XD and 5XD, this micro-precision milling cutter delivers remarkable performance even in the most demanding and intricate of applications.

The RF 100 AL Micro impresses with incredible material removal rates that can reduce cycle times by up to 76% when compared to conventional small end mills. Impeccable surface finishes and burr control complement this dramatic productivity improvement, whilst the formidable process reliability concerns are eliminated through the tool's intelligent design.

Key to the RF 100 AL Micro's exceptional performance is the combination of advanced technologies. An ultra-thin Carbo+ coating reduces wear and significantly increases machining performance and extends tool life, particularly crucial in the micro-diameter range where tool integrity is paramount. The new round bevel chamfer delivers perfectly smooth surface finishes. Furthermore, it strengthens the integrity of the cutting edge to prevent edge chipping and tool breakage, which is critical when machining with small tools. With four or six through coolant channels incorporated as part of the innovative GühroJet internal cooling system, chip removal is reliable, efficient, and it prevents the re-cutting of swarf, even in the deepest of cavities.

Available with either corner radius or corner chamfer configurations, the RF 100 AL Micro offers flexibility for the end user by supporting ramping, slotting, trochoidal milling and plunging. The RF 100 AL Micro demonstrates significantly enhanced machining performance at both medium and high speeds, making it ideally suited to the varied demands of modern production environments. Very high process reliability is ensured through perfected cooling and chip removal capabilities and the highly stable three-flute configuration.

Complementing the micro range, the RF 100 AL solid carbide milling cutter extends Gühring's aluminium machining expertise across standard diameters from 1 to 25mm. Like the Micro series, this 3-flute cutter unleashes impressive cutting performance across aluminium, non-ferrous metals and plastics. Capable of delivering an impressive 30% increase in machining performance, real-world application data demonstrates the RF 100 AL's ability to reduce machining time by 59% and generate tool life improvements of 54% compared to competitive solutions.

The nano-polished round bevel support chamfer represents a breakthrough in milling technology, enabling the RF 100 AL to achieve the tightest tolerances and optimum performance levels. This precision 3-flute geometry presents a large polished flute profile that delivers extended tool life and superior chip removal characteristics. The reinforced core provides exceptional stability, particularly important when machining thin-walled, vibration-sensitive parts as well as cutting at more robust machining parameters. Available with short, medium and long reach variants with various neck clearances offered, the series offers flexibility for profiling and machining difficult to access surfaces.

With a diameter range from 1 to 20mm with an extensive selection of corner radii from R 0.1 to 4mm, the RF 100 AL demonstrates incredible flexibility for any application requirement. Both the RF 100 AL Micro and RF 100 AL are available with Guhring's advanced Carbo+ coating option, ideal for dry and MQL machining. This extra-smooth coating prevents built-up edge formation and guarantees extended tool life, making it particularly beneficial for high-volume production environments where tool longevity directly impacts manufacturing economics.
