The new T-Carb end mills from Wokingham-based SGS Carbide Tool (UK) Ltd (www.sgstool.com) are designed for aggressive high-speed machining using trochoidal and peel-milling techniques (Hall 4 Stand 4210). Their six flutes allow high feed rates at reduced tool loads, ultimately preventing breakage and failure, while variable-pitch geometry results in shorter cycle times and lower costs for aggressive roughing and finishing operations.

Suitable workpiece materials range from common steels to stainless steels, high-temperature alloys and titanium alloys; indeed, the T-Carb range is particularly suited to titanium milling applications (the geometry is suitable for workpiece materials up to 50HRC). Furthermore, because the six flutes feature a variable geometry and are ground in a variable index pattern, the rhythmic striking of the cutting edges against the workpiece material is disrupted, helping to prevent the onset of chatter.

Joining the T-Carb range will be the new Series 33 range of high-performance three-flute end mills. A stepped core design provides optimal chip control and rigidity when the flute is completely engaged, while the geometry features a variable helix and pitch configuration to provide chatter and vibration suppression. Finally, symmetrical end gashing combines balance with strength and ramping capabilities.

Available with a corner radius, Series 33 end mills are ideal for aggressive ramping, pocketing and slotting of materials such as stainless steel, titanium and Inconel. Like the T-Carb range, Series 33 end mills are available with SGS’s own Ti-AMITE-X abrasion-resistant coating.
