Drilling is not always a simple, straightforward job. Workpiece instability, vibrations, and chip control are just a few challenges typically encountered in drilling applications. In addition to these challenges, the cost per hole becomes a critical subject in many shops with pressure to achieve sustainable production at the lowest cost possible. The Top Drill Modular X (TDMX) holemaking solution is able to address such machining applications and economic requirements with ease.
Tube sheets, baffles, I-beams, valves, axles and track drive units are just a few examples of components that can be machined with more confidence thanks to the TDMX drill, its material-specific inserts and optimised body design.
The new Widia TDMX solid carbide tipped modular drills have risen to the next level of performance and reliability for this style of tool. A number of unique features have been engineered to optimise performance in a wide range of materials and for a wide range of machines.
The Top Drill Modular TDMX by Widia is one of those tools that do just that. With a front-clamping design, TDMX is an excellent choice for high-demanding drilling applications. Front clamping removes the need for stopping to dissemble the body from the holder and change the insert. This tool has stability and reliability combined into one modular drill system.
A carefully thought out design includes specific features that add to the overall efficiency of the Top Drill Modular. TDMX includes a double angle pocket seat design and a flanged shank that provide outstanding flexibility and stability. The body design, which includes coolant channels, polished flutes and margins, enables the highest machining quality to make insert changes easy. Front clamping adds stability, ease of use and quality for an improved cost per hole.
Coolant channels exit right behind the cutting edge to ensure the best coolant delivery. Two standard screws in the front work to clamp and unclamp the insert without disassembling the tool from the holder. Margin lands on the entire body length ensure the straightness and increases hole quality, while polished flutes improve chip evacuation. The flanged shank increase the overall drill stability, above all in deep-drilling applications, and the cylindrical shank with flat make it suitable for machining and turning centers. TDMX is part of the new 2019 WIDIA line of Advances products.
The TDMX drills are now available with additional drilling depths and also an additional drill point for tough applications. New lengths available are 1.5, 3, 5, 8 and 12XD L/D ratios. A new drill point for deep drilling applications is also available.
