Increased performance in all parameters
MPS1 drills were developed to meet future technological standards. The innovative cutting edge geometry with the reworked four margin flute design improves hole concentricity and surface finish. The newly designed straighter cutting edge together with MIRACLE SIGMA coating enables smoother penetration at the highest feeds and speeds, thereby increasing overall productivity. Mitsubishi Materials TRI-COOLANT technology provides optimised lubrication at the cutting point of the drill, offering reliability and increased performance under demanding machining conditions. In addition MQL drilling is possible with the MPS1 drill and is a suitable way to increase cost efficiencies. MPS1 drills can be used for multiple applications and materials and are ideal for steels, cast iron and stainless steels.
MPS1 Drill Series – The latest in high performance drilling
MPS1 drills have been designed with the aim of double performance - use the very highest cutting parameters or obtain extra long tool life. This has been achieved by combining the best of proven existing features together with the very latest state of the art technology.
Cutting Edge
MPS1 drills also use a newly designed straighter cutting edge that was found to offer a smoother cutting action for improved penetration at the highest feeds and speeds. The edge also works effectively in tandem with the new MIRACLE SIGMA based coating to provide excellent tool life.
Proven Features
The reworked double margin flute is part of the proven existing technology that provides the highest hole accuracy, efficient chip evacuation and smooth surface finishes.
Mitsubishi’s innovative Tri-Coolant holes are optimised for MQL and have also shown to greatly improve coolant flow where it matters most, at the cutting point of the drill. Extensive flow dynamics research revealed not just the benefits of extra volume, but also the way in which the coolant flowed more efficiently from the hole. It was found that by optimising the shape, more than double the amount of coolant is discharged and at greater speeds than with conventional round type through coolant holes. It is this combination of extra flow and improved delivery to the cutting point that is critical for effectively removing chips. The efficient removal of chips enables continuous high performance across a wide range of work materials and applications.
Miracle Sigma Coating
The new MIRACLE SIGMA based PVD accumulated Al-Ti-Cr-N coating provides the protection needed to ensure longer tool life, especially at the higher cutting speeds and feeds that are demanded by today’s modern production environment. Additionally the polished Zero-μ surface of the coating provides several important assets such as excellent resistance to welding and a very low coefficient of friction for a sharper but reliable cutting action. The smooth surface also helps greatly towards efficient chip evacuation, an important aspect of overall performance considering the extra material generated by higher feeds and speeds. Typical cutting speeds when drilling carbon steel of around 160m/min can be increased to 220m/min and feed rates upped from 0.25 mm/rev to 0.35mm /rev that gives a huge overall linear feed increase from 1600mm/min to 3080 mm/min. The all important carbide substrate provides the toughness and hardness required to compliment the performance of the new coating.
