2-Flute Solid Carbide Micro Drill Overview<\/h2>\n

This 2-flute solid carbide micro drill is designed for precision small-hole machining in selected steels, stainless steels and non-ferrous metals. The supplied series covers cutting diameters from \u00d80.5 to \u00d81.7 mm, with flute lengths and overall lengths arranged for different reach requirements. Fine-grain solid carbide and precision-ground micro geometry support rigidity, controlled entry and chip evacuation. Final surface configuration, coating and cutting data should be matched to the actual workpiece material, hole depth, machine rigidity and coolant condition.<\/p>\n

\n

2-Flute Micro Geometry<\/h4>\n

Two spiral flutes provide a practical balance between cutting-edge support and chip space for small-diameter metal drilling.<\/p>\n<\/div>\n

\n

Reach-Specific Length Options<\/h4>\n

Flute lengths from 6 to 14 mm and overall lengths of 30 or 35 mm provide different reach options for the listed diameter groups.<\/p>\n<\/div>\n

\n

Karbida Padat Berbutir Halus<\/h4>\n

The carbide substrate provides rigidity and edge support for controlled entry and stable micro-hole production.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

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

Precision-Ground Point Geometry<\/h4>\n

Supports controlled entry and balanced cutting-lip engagement when used on a properly prepared surface with low runout.<\/p>\n<\/div>\n

\n

Two-Flute Chip Evacuation<\/h4>\n

Provides chip space for blind, through and functional small-hole operations while maintaining cutting-edge support.<\/p>\n<\/div>\n

\n

Diameter-Specific Reach<\/h4>\n

Multiple flute-length groups allow the drill reach to be selected according to hole depth while avoiding unnecessary overhang.<\/p>\n<\/div>\n

\n

Material-Specific Configuration<\/h4>\n

Surface finish, coating, edge preparation and coolant method can be reviewed for steel, stainless-steel or non-ferrous applications.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
