HRC65 Solid Carbide Corner Radius End Mill Overview<\/h2>\n

The HRC65 solid carbide corner radius end mill is engineered for stable profiling, pocket finishing and semi-finishing in hardened steel, heat-treated steel, die steel and mold steel. Its 4-flute geometry provides a rigid core and consistent cutting engagement, while the corner radius reinforces the transition between the end and peripheral cutting edges. Ultra-fine-grain carbide and heat-resistant coating options support wear resistance, edge stability and repeatable surface quality in demanding mold and high-hardness machining.<\/p>\n

Key Product Advantages<\/h3>\n
\n
\n

Reinforced Corner<\/h4>\n

The corner radius improves edge strength compared with a sharp-corner square end mill and supports controlled part fillets.<\/p>\n<\/div>\n

\n

Rigid 4-Flute Core<\/h4>\n

Four cutting edges and a rigid core support stable side milling, profiling and finishing in hardened steel.<\/p>\n<\/div>\n

\n

Heat-Resistant Coating<\/h4>\n

Application-matched coatings help resist oxidation, abrasive wear and high cutting temperatures.<\/p>\n<\/div>\n

\n

Standard & Custom Supply<\/h4>\n

Diameter, radius, flute length, shank, overall length, geometry and marking can be reviewed by drawing.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

<\/p>\n

\n

Recommended Applications<\/h3>\n

Recommended for profile milling, pocket finishing, contour machining, corner finishing and controlled-engagement semi-finishing in rigid CNC machining conditions.<\/p>\n

Application Note:<\/strong> HRC65 is the series positioning rather than a universal guarantee for every workpiece at exactly 65 HRC. Confirm the steel grade, actual hardness, operation, tool overhang, holder condition and machine rigidity before machining near the upper range.<\/div>\n<\/section>\n
