Monaghan Solid Carbide Drills Optimize Holemaking Performance

Monaghan Tooling Group introduces MK Tools’ Speed Drill S2 and S4 series of solid carbide drills in standard sizes from 3 to 20 mm. All models feature two-flute geometry with a 30-degree helix angle for superior chip evacuation, and 140-degree point geometry for precision holemaking in materials such as carbon steel, cast iron, grey cast iron, alloys and other ferrous and non-ferrous materials.

The S2 is said to be well suited for general purpose applications, in sizes from 3 × D or 5 × D with coolant through or noncoolant fed designs. With four-guide lands, the S4 holds sizing better for increased performance and higher-quality holemaking. S4 models are available in 5 × D and 8 × D sizes with coolant through only. Both the S2 and S4 series are manufactured from premium carbide feedstock with the latest generation of CNC grinding machines. A straight main cutting edge and special slot form are said to produce optimized cost/performance ratios, yielding low costs per piece. With original OEM regrinding, including coatings, they deliver new drill performance and a low cost-per-piece throughout their long service life. MK Tools Speed Drills from Monaghan Tooling Group are ideal for high-volume production runs to one-off machine shop projects, and are well suited for applications where precision and repeatability are required, such as connecting rods, injection pumps, wheel carriers, guide wheel shafts and more.

All MK Tools standard drills feature proprietary GTX coating, a multilayer aluminum chromium nitride coating that reduces reaming resistance for longer tool life and better chip evacuation. This and other advanced coating options for optimum performance, for new tools and regrinds, are performed in-house to reduce lead times.
