Kennametal 5351834 Square End Mill 6 Flute Solid Carbide

Product Description

The KENNAMETAL 5351834 is a solid carbide square end mill designed for high-performance milling in demanding material applications. Built to UJDE series standards, it features a 0.625 inch diameter cutting face, a 1.25 inch length of cut, and a 3.5 inch overall length. The six-flute geometry with a 38-degree helix angle promotes efficient chip evacuation and surface finish quality in aggressive feed conditions. An AlTiN coating provides thermal resistance and wear protection when machining at elevated cutting speeds. This tool is used by machinists and tool-and-die professionals in production and job-shop environments where tool life and dimensional accuracy are critical.

The 5351834 is suited for milling steel, stainless steel, high-temperature alloys, and hardened materials — covering ISO material codes P, M, S, and H. The variable index design reduces harmonic vibration during cut, making it a dependable choice for finishing and semi-finishing passes where chatter control matters. It is a single-end, right-hand cut tool with a right-hand spiral flute and a 0.625 inch shank diameter that fits standard ER and side-lock toolholders common in CNC machining centers.

Key Features

• Six-flute configuration supports higher feed rates and improved surface finish compared to four-flute designs
• 38-degree helix angle promotes smooth chip flow in ferrous and high-temp alloy cutting
• AlTiN coating (material grade KCSM15) provides heat resistance for dry and near-dry machining
• Variable index flute spacing reduces resonance and chatter during aggressive milling
• Centercutting geometry allows plunge entry in addition to peripheral milling
• Tight diameter tolerance of +0.0000/-0.0020 inches supports dimensional accuracy in close-tolerance work

Compatibility

Designed for use in CNC machining centers with standard 0.625 inch collet or side-lock toolholders. Rated for primary workpiece materials including steel, stainless steel, high-temperature alloys, and hardened materials (ISO codes P, M, S, H) per KENNAMETAL UJDE series specifications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore and shank are clean and free of chips before seating the end mill. Confirm proper stick-out length and runout with a dial indicator before cutting. Follow the machine tool manufacturer torque specifications for collet nuts or side-lock set screws — do not overtighten.
