140\u00b0 Solid Carbide Twist Drill Overview<\/h2>\n

This 140\u00b0 solid carbide twist drill is designed for high-precision hole machining in carbon steel, alloy steel, pre-hardened steel, cast iron and other confirmed metal grades. The precision-ground 140\u00b0 point provides a flatter cutting profile for controlled penetration, while two spiral flutes support continuous chip evacuation in blind-hole and through-hole drilling. Manufactured from fine-grain solid carbide, the drill provides high rigidity, repeatable dimensional performance and wear resistance for CNC production. Standard 3\u00d7D, 5\u00d7D and 8\u00d7D configurations are available from \u00d83.0 to \u00d820.0 mm.<\/p>\n

Key Configuration<\/h3>\n
\n
\n

Precision-Ground 140\u00b0 Point<\/h4>\n

The flatter 140\u00b0 point supports controlled penetration and stable cutting when used with a rigid machine setup and accurate toolholding.<\/p>\n<\/div>\n

\n

Two Spiral Flutes<\/h4>\n

Two precision-ground spiral flutes guide chips away from the cutting zone during blind-hole and through-hole drilling.<\/p>\n<\/div>\n

\n

Application-Specific Options<\/h4>\n

Coating, edge honing, point thinning, shank dimensions and drilling depth can be selected according to the material grade and production requirement.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

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

Controlled Penetration<\/h4>\n

The 140\u00b0 point profile supports a controlled entry and stable drilling cycle in suitable precision metal-machining applications.<\/p>\n<\/div>\n

\n

Consistent Hole Geometry<\/h4>\n

Precision-ground cutting lips and solid-carbide rigidity help support repeatable hole diameter, straightness and surface quality.<\/p>\n<\/div>\n

\n

Efficient Chip Evacuation<\/h4>\n

Two spiral flutes provide a direct chip path for blind-hole and through-hole drilling across the standard depth series.<\/p>\n<\/div>\n

\n

3D \/ 5D \/ 8D Selection<\/h4>\n

Three depth configurations allow the tool length to be selected according to rigidity, hole depth, chip removal and production requirements.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
