Iscar 3105516 Indexable Plunge End Mill 1.5in 4 Flute

Product Description

The ISCAR 3105516 is an indexable plunge end mill from the TangPlunge series, designed for high-performance plunge milling and ramping operations in metalworking applications. It features a 1.5-inch cutting diameter, a 1.25-inch straight shank, and a maximum depth of cut of 0.118 inches per pass. The body accepts HTP LNHT 1006 insert style inserts and is classified under the HTP-LN10 toolholder style. Through-coolant capability is built in, supporting chip evacuation and tool life in demanding cuts. This toolholder is installed by machinists and CNC operators working in production or job shop environments.

The 3105516 is suited for milling operations on a wide range of workpiece materials including steel, cast iron, stainless steel, high-temperature alloys, and non-ferrous metals, consistent with the universal material code designations H, K, M, P, and S per ISO 13399 classification. With four cutter inserts and through-coolant delivery, it is well matched to vertical machining centers and CNC milling machines where plunge roughing or pocketing cycles are common. The straight shank configuration allows direct mounting in standard end mill holders or hydraulic chucks.

Compatibility

Designed for use with HTP LNHT 1006 inserts in the HTP-LN10 toolholder style. Compatible workpiece material codes per ISO 13399: H, K, M, P, and S, covering hardened materials, cast iron, stainless steel, carbon steel, and high-temperature alloys.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be brought to a full stop and the tool changer or spindle locked before mounting or removing the toolholder. Confirm insert seating and screw torque according to ISCAR insert clamping guidelines before initiating any cutting cycle. Through-coolant lines should be verified for flow and pressure before operation to prevent thermal damage to inserts.
