ريشة حفر HSS M2 بثلاث حواف قطع 4 مم

The Ronix RH-5765 M2 HSS Three-Flute Drill Bit 4 mm is designed for precision hole drilling with a 4 mm size, 43 mm working length, and 95 mm overall length. Made from M2 material with 63–65 HRC hardness and a titanium surface finish, this drill bit supports durability, surface quality, and general drilling performance. Its 3-flute cutting design increases chip removal rate, helps reduce drilling time, and reduces thermal and mechanical stresses on the cutting part of the drill bit.
