Kennametal 4071923 Corner Chamfer End Mill 0.5in 4 Flute

Product Description

The KENNAMETAL 4071923 is a solid carbide corner chamfer end mill designed for high-performance material removal in demanding machining applications. Built to the HPHV series specification, this single-end tool features a 0.5-inch diameter, four flutes with variable flute geometry, and a 45-degree chamfer angle. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and hard materials. With a 38-degree medium helix and centercutting capability, this end mill handles roughing and finishing passes with consistent results. It is installed by machinists and CNC operators in production and job-shop environments.

This end mill is suited for use on steel, stainless steel, cast iron, and hard materials. Its centercutting design supports shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing operations. The Weldon flat shank provides secure tool holding in standard end mill holders and collet chucks. With a 1.625-inch length of cut and 4-inch overall length, this tool fits typical vertical and horizontal machining center setups where reach and rigidity are both critical factors.

Key Features

• 45-degree chamfer angle with variable flute spacing for reduced chatter
• AlTiN PVD coating rated for steel, stainless steel, cast iron, and hard material grades
• Centercutting geometry enables plunging, helical interpolation, and ramp-down entry
• Weldon flat shank for positive drive and reduced pull-out risk
• Right-hand cutting and right-hand flute direction for standard spindle operation
• KCPM15 carbide grade engineered for balanced wear resistance and toughness

Compatibility

Designed as an OEM-style solid carbide end mill compatible with operations on steel (P), stainless steel (M), cast iron (K), and hard materials (H) per ISO material classification. Catalog reference number HPHV500S4163.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Use a calibrated torque wrench when tightening the Weldon flat set screw to the tool holder manufacturer specification. Verify runout with a dial indicator after installation before starting a cut. Handle solid carbide tooling carefully to avoid edge chipping during setup.
