Manufacturers and die & mold shops can abolish chatter problems in several milling operations with Iscar's new Chatterfree carbide endmill. The cutters' variable-pitch flute pattern annihilates harmonic vibration, the chief source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling. In addition, end users also report longer edge life due to reduced chatter. The chatter-free ability is attainable in both solid carbide endmills and tips in Iscar's MULTI-MASTER replaceable-tip family. Diameter range is 6 to 20mm for the solid carbide endmills, and 8 to 20mm for MULTI-MASTER tips. These unique endmills are ideal for low power machines with ISO40 or BT40 adaptations. The solid carbide construction can handle full slot machining up to 2xD. Depth capability on the replaceable-tip version is more bounded since the active length is shorter. In full slotting functions on alloy steel, the solid carbide version conveniently handles 0.03-0.05 feed rates at 180-220mm/min surface speed and 2xD depth of cut.

FINISHRED - Revolutionary Solid Carbide Endmills

Iscar is introducing the EFR.. B44 and the MM EFS.. Finishred a revolutionary solid carbide endmill family. The Finishred carbide endmill is a blend of both roughing and finishing endmills in a single tool. Roughing endmills remove material from work pieces more swiftly and effectively than traditional endmills. Yet, roughing endmills leave grooves on the machined surface. Accordingly, after using a roughing endmill, a finishing endmill has to be used in order to obtain a smooth surface finish. This means time-consuming tool change, setup time and necessity of maintaining two endmill types in the inventory.

Features of the Finishred Endmills:

The EFR.. B44 and the MM EFS.. endmills feature four flutes with 45 degree helix, 2 serrated flutes and two continuous flutes.

The cutting edges of the finishing flutes are radially further from the tool axis than the cutting edges of the serrated flutes. The finishing flutes remove the grooves caused by the roughing flutes, leaving a smooth surface finish.

The tool is fully capable and enables running at rough machining parameters, ending in finish surface quality.

The extraordinary tool design lessens vibration at high load applications.

The tool creates short and long chips simultaneously. This chip mixture is evacuated more efficiently than each individual chip type, an excellent solution in slotting and cavity milling applications.

The Finishred is also available with the Multi-Master indexable milling head option which merges the Finishred features with the benefit of little setup time, no regrinding costs and the extended range of shank and extension options are available for the Multi-Master milling heads.

A single tool replaces the roughing and finishing endmills; therefore downsizing stock.

Tool change and setup time can be disregarded.

New Chip Splitting Solid Carbide Endmills for High Metal Removal Rates

ISCAR is announcing the ECP-3/4L family of chip splitting endmills. The new endmills are offered with three and 4 38 degree flutes in grade IC900. They feature 2xD and long shanks with scaled down neck diameter, which allow machining along high shoulders, at high feeds. These endmills, due to their chip splitting element and force distribution can be used very proficiently on low power machines (CAT40/BT40/ISO40). The serrated cutting edge features flat peaks which leave a better surface finish, in comparison to the current rougher carbide endmill. The ECP endmills are advocated for machining austenitic and martensitic stainless steel, at up to 2xD depth of cut. They can be used on alloyed steel as well. All of the introductory tests conducted at several customers' locations showed extraordinary results.
