Carbide Twist Drill for HRC50\u201355 Mold Steel<\/h2>\n

This coated solid carbide twist drill is designed for stable CNC hole machining in heat-treated mold steels with a measured hardness of HRC50\u201355. Its rigid carbide body, precision-ground two-flute geometry and wear-resistant coating help manage cutting-edge load, heat and abrasive wear. The standard configuration uses a cylindrical straight shank and external coolant and is intended for rigid machining centers, low-runout clamping, controlled entry and hole depths compatible with the selected flute length.<\/p>\n

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

\u25cf<\/span>
\nRigid Solid-Carbide Body<\/span><\/h4>\n

High tool rigidity supports edge stability and helps limit deflection when drilling heat-treated mold steel.<\/p>\n<\/div>\n

\n

\u25cf<\/span>
\nWear-Resistant Coating<\/span><\/h4>\n

A suitable PVD coating protects the cutting zone against heat and abrasive wear during continuous CNC drilling.<\/p>\n<\/div>\n

\n

\u25cf<\/span>
\nTwo-Flute Chip Space<\/span><\/h4>\n

The two-flute design provides chip space and supports controlled chip evacuation when coolant access is maintained.<\/p>\n<\/div>\n

\n

\u25cf<\/span>
\nPrecision-Ground Point<\/span><\/h4>\n

Symmetrical cutting lips support controlled entry and stable cutting when holder runout and workpiece clamping are controlled.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Mold Steel & Hardness Guidance<\/h3>\n

Tool selection should be based on measured workpiece hardness rather than the material-grade name alone. Confirm the heat-treatment condition and local surface hardness before drilling.<\/p>\n
