Monaghan Tooling Group’s R4 Speed Drill Series: Optimized for High-Speed, Precision Holemaking!

Monaghan Tooling Group introduces the MK Tools R4 Speed Drill series, a range of high-performance solid carbide drills designed for high-speed, precision holemaking in various materials such as carbon steel, cast iron, gray cast iron, and diverse alloys. Engineered for demanding machining environments, these drills are available in standard sizes from 3-20 mm and offer drilling depths of 3 × D or 5 × D, with built-in through-coolant capabilities to enhance performance.

The R4 Speed Drill Series is distinguished by its two-flute geometry with a 30-degree helix angle, optimizing chip evacuation and significantly reducing downtime. The 140-degree-point self-centering geometry eliminates the need for pre-drilling, streamlining the process and boosting efficiency. Each drill is precision ground from premium carbide feedstock, ensuring durability and high-quality performance.

The drills feature a four-facet point geometry with cross-web thinning and a large radius, which provide exceptional stability and reduce cutting forces, contributing to smoother operations and longer tool life. Additionally, polished parabolic flutes and two guide lands offer improved centering, reduced vibration, and a better surface finish, making them ideal for high-speed applications in sectors such as automotive, aerospace, and general machining.

Common applications for the R4 Speed Drills include the machining of components like connecting rods, injection pumps, wheel carriers, guide wheel shafts, and more. The tools’ design is tailored to meet the stringent demands of high-speed manufacturing, where performance, precision, and reliability are paramount.

Monaghan Tooling Group also provides OEM regrinding services, including advanced coating re-application, to further enhance the longevity and efficiency of their drills. All standard drills are coated with MK Tools’ GTX coating, a multilayer aluminum chromium nitride coating that reduces drilling resistance, improves chip evacuation, and extends tool life. Their in-house coating capabilities allow for faster lead times for both new drills and regrinds, ensuring that customers receive high-quality tools with minimal wait times.

The R4 Speed Drill Series is engineered to deliver optimal results in a variety of machining applications, combining cutting-edge design with advanced coatings to ensure superior performance and extended tool life.
