Description

DRILL 2.65xD3x12x38 55 hrc | Precision CNC Tooling for Hardened Steel

Unlock superior drilling precision with our 2.65mm Solid Carbide Drill, engineered specifically for industrial machining and CNC applications. This high-performance cutting tool is manufactured from premium micro-grain carbide, capable of handling materials with a hardness of up to 55 HRC. Whether you are working with alloy steels, tool steels, cast iron, or stainless steel, this drill bit ensures exceptional wear resistance and extended tool life, reducing the need for frequent tool changes in high-production environments.

The drill features a robust 3mm reinforced shank (h6 tolerance), which provides maximum rigidity and reduces vibration (chatter) during high-speed operations. The 2.65mm cutting diameter is paired with a 12mm flute length, making it an ideal “stub drill” design. Stub lengths are crucial for micro-drilling because the shorter flute length significantly increases the core strength of the tool, preventing breakage and ensuring high hole straightness and accuracy. With an Overall Length (OAL) of 38mm, this tool fits standard collets and holders found in CNC machining centers, VMCs, and Swiss-type lathes.

Key Technical Features:

Extreme Hardness: Rated for 55 HRC, making it perfect for drilling difficult-to-machine materials like mold steels (P20, H13) and hardened alloys.

Precision Geometry: The specialized point angle (typically 135° or 140°) allows for excellent self-centering capabilities, eliminating the need for spot drilling in many applications.

Efficient Chip Evacuation: The advanced flute geometry promotes smooth chip removal, preventing heat buildup and work-hardening of the material.

Versatile Application: Suitable for drilling, boring, and precision hole-making in automotive, aerospace, die & mold, and medical component manufacturing.

By upgrading to this solid carbide twist drill, machinists can achieve tighter tolerances and superior surface finishes compared to standard HSS or Cobalt drills. It is compatible with all major CNC operating systems and manual milling machines requiring high-rigidity tooling. Optimize your cycle times and ensure process reliability with this industrial-grade 2.65mm carbide drill.
