Incorporating a corner radius and central through coolant supply, the new MD377 utilises Walter’s proven HPC Ti40 titanium geometry and new WTZ coating that makes it perfect for full slotting up to 1XD, ramping, shoulder milling and plunging. Also, the MD377 Supreme is suitable for dynamic milling processes. In comparison, the MC377 has a centre cutting geometry without the through coolant supply.

Chipbreaker options cover finishing to roughing and the company is introducing the PMG chipbreaker for medium to roughing when machining steel.

The coating properties on the rake and flank faces provide good wear resistance, the manufacturer states. The black and gold appearance and stark contrast of the tools are more than just cosmetic in nature. The black rake face is composed of a highly uniform alumina layer, which reduces wear, suppresses cratering, and reduces fracturing, the company states. The gold flank includes a hard surface layer, a highly uniform alumina layer, and a titanium carbonitride (TiCN) layer. These layers on the flank work together to improve the wear-resistant properties of the insert and to suppress surface abrasion. Below the coating, the new carbide substrate displays enhanced resistance to plastic deformation and exhibits increased temperature resistance, the manufacturer states.

OSG’s HY-PRO® VGM variable geometry end mill series is available in 5-, 6- and 7-flute line-ups with multiple lengths of cut, with both square and corner radius variations. Featuring geometry and coating that reduces vibration, maintains edge sharpness and tool rigidity, all while providing exceptional wear resistance.

The MD377 Supreme is available with a range of corner radii in diameters of 6, 8, 10, 12, 16, 20 and 25mm with a flute length of 13mm on the 6mm diameter tool ranging up to 45mm on the 25mm tool with each tool designed with a back radius into a necked diameter for clearance when machining deep cavities.

From a process security perspective, both the MC377 and MD377 are available with plain cylindrical shank across all diameters but from 16mm to 25mm diameter there is also the option of a cylindrical shank with clamping flat to DIN6535 HB to prevent tool pull out and increase stability. In addition to the standard ranges with cutting lengths up to 2XD, Walter also offers custom-designed tools via the Xpress service with short delivery times.

This high material removal rate is a credit to the optimised cutting geometry and the five cutting edges that can improve productivity levels and reduce vibration credit to its differential pitch design.

Developed as high-end specialist tools for the aviation, motor sport and medical industries, the new arrivals are universal tools that are suitable for roughing, semi-finishing and finishing operations.

Kyocera has released the CA115P/CA125P CVD-coated carbide for machining steel. This offering combines a coating, carbide substrate, and chipbreakers.

While suitable for machining steel in continuous to heavy-interrupted applications with options for finishing and roughing, these tools also can be used for external and internal turning, facing, and boring.

Depending upon the tool diameter, each MC377 tool is available with a choice of corner radii from 0.2 to 4mm. The series has a flute length that ranges from 6mm on the 2mm diameter tool through to 45mm on the 25mm diameter tool. The MC377 cutter range is also designed with the back radius into a necked diameter feature for clearance.

The impressive new MC377 end mill without corner radii is available in diameters of 2, 3, 4, 5, 6, 8, 10 and 12mm whilst the MC377 with corner radii is offered with a 2, 3, 4, 5, 6, 8, 10, 12, 16, 20 and 25mm diameter with the 2mm tool having a 3-flute geometry and all other diameters having 4-flutes.

The MD377 Supreme has been developed for the aviation and aerospace industry and is therefore precisely matched to its requirements. The titanium specialist with a central coolant supply represents a benchmark when it comes to machining engine and structural components. It allows for tight tolerance machining and it stands out thanks to its extremely high metal removal rates.

In contrast, the MC377 is a four-flute titanium end mill that is also suitable for ISO P and M material designations. This diversity is credit to a tough AlCrN coating that works with Walter’s WK40EA substrate that makes the MC377 suitable for steel, stainless as well as titanium alloys. With regards to the MD377, the tool life and performance is assured with the latest Walter-exclusive AlTiN+ZrN (WTZ) coating with HIPIMS technology.

Both tools are the perfect partners for the machining of small parts, engine components or structural components as well as additively manufactured components in the aerospace, motor sport and medical technology sectors.

According to the company, the new tools extend tool life in numerous machining scenarios. For example, the CA115P is suitable for continuous to light-interrupted machining. Conversely, the CA125P is optimized for continuous to heavy-interrupted machining.
