Widia is releasing the M1600 face mill for roughing to semi-finishing operations in steel, stainless steel, cast iron and nodular iron materials. With 16 cutting edges and a novel insert design, the M1600 performs in various machining conditions, including low-power machines, unstable set ups, long overhangs, weak machines or weak fixtures.

The precision-ground insert with a positive geometry enables low cutting forces and low power consumption, resulting in higher tool life and low cost per edge. Widia’s M1600 has one universal insert geometry in three versatile grades: WP35CM, WK15CM and WU20PM.

The WP35CM grade targets all types of steels, while the WK15CM grade is for cast-iron materials and performs best in dry applications, but can also be used wet. The universal WU20PM grade is for the machining of steel, stainless steel and high-temperature alloys in both dry and wet applications.

Notably, the ‘smart’ insert design features a seating surface below the cutting edge that promotes smooth chip flow and reduces cutting forces on the tool. The insert also has a curved cutting edge and is axially positive, resulting in reduced power consumption. These key design features, coupled with 16 cutting edges, make M1600 an economical face milling option.

M1600 face mills are available in six metric diameter ranges between 50 and 160 mm. Inch diameters will follow shortly. Orders for the M1600 bodies and inserts, as well as other Widia tooling, can be placed through Widia’s authorised distribution partners.

The productivity of deep-hole drilling has taken a step forward with the arrival of a four-flute series of gun drills from Guhring. VB 80 deep-hole drills (with a solid-carbide head) and the VB 100 solid-carbide series are productivity partners for cast-iron drilling.

These straight flute deep-hole drills are robust with a geometry that ensures the drill core is more than 50% of the overall diameter. Guhring has also developed geometry that consists of two core cutting edges supported by four outer flutes that are axially displaced to split the chips and improve centring and precision, while reducing cutting forces. As a result, the bottom of the hole will be two-stepped as the drill has a 141° angle on the primary cutting edge, followed by a 145° angle on the outer cutting edges. Four cooling channels further improve chip clearance, allowing high-pressure coolant to each of the four cutting edges – prolonging tool life by preventing swarf re-cutting and creating an efficient chip removal sequence.

VB 80 and VB 100 deep-hole drills also consist of four round margins with a 90° division that further enhances precision, concentricity and surface finishes down to IT6. With the abrasive wear divided through four flutes as opposed to two, as in most ranges, the VB 80 and VB 100 improve tool life and performance significantly. In fact, the drills have reduced cycle times by more than 30% during field tests, while extending tool life, hole quality and overall performance far beyond the realms of two-flute gun drill variants.

At present, both the VB 80 and VB 100 series are available in diameters from 13.5 to 28 mm diameter, with flute lengths up to 500 mm.
