en.Wedoany.com Reported - UK's TaeguTec has launched two new drill/mill end mill series that eliminate the need for tool changes between drilling and milling operations, thereby shortening machining cycle times. The SDM solid carbide end mill (part of the ApexMill series) and the MXDM exchangeable head tool for MaxiRush holders both enable manufacturers to drill to a depth of 1×D and then immediately transition into milling without a tool change.
Completing drilling and milling with the same tool eliminates tool changes between operations and reduces non-productive time, significantly boosting productivity and lowering inventory costs. In high-mix, low-volume production environments where frequent tool changes greatly impact efficiency, the advantages of this design are particularly pronounced.
The SDM end mill features a three-flute design, with an optimised wide flute geometry that ensures smooth chip evacuation at a drilling depth of 1×D. The tool's tapered core design enhances rigidity, making it suitable for various operations including side milling, slot milling and circular interpolation, achieving maximum material removal rates. The variable helix angle design enhances cutting stability, reduces vibration and delivers good surface finish. Additionally, the SDM end mill is equipped with helical internal coolant channels, which are crucial for effective chip evacuation during drilling.
The SDM end mill is available in diameters of 10, 12, 16 and 20 mm, manufactured in TaeguTec's TT5525 grade, and offers drilling feed rates comparable to standard drills. A cutting speed of up to 120 m/min is recommended for machining carbon and alloy steels, with an optimised speed of 60 m/min for stainless steel. After drilling, the tool can immediately transition into milling at the drilled depth, with a recommended cutting speed of 150 m/min for carbon and alloy steels.
In response to rising carbide costs, TaeguTec has introduced the MXDM exchangeable head tool. This product offers the same drilling and milling performance as the SDM series within the MaxiRush modular tooling system, providing additional flexibility for manufacturers already using MaxiRush holders. The MXDM head can be quickly exchanged to suit a variety of machining operations. The three-flute MXDM head adopts the same wide flute design and tapered core geometry as the SDM end mill, ensuring consistent performance between the two series.
Similar to the SDM solid carbide end mill, the MXDM head is available in diameters ranging from 10 to 20 mm, manufactured in TaeguTec's TT5523 grade, and requires the use of reinforced MXSSD shanks for optimal performance. Both series support immediate side milling, slot milling, circular interpolation, helical ramping and profiling operations after drilling. The MXDM is particularly suited for machining carbon steel, alloy steel and stainless steel in the aerospace, automotive and general engineering sectors.
