DRILL 2.1xD3x12x38 55 hrc

Description

DRILL 2.1xD3x12x38 55 hrc is a high-precision solid carbide micro drill designed for accurate and stable hole making in medium-hard materials up to 55 HRC. This micro drill is widely used for drilling stainless steel (SS304, SS316), EN8, EN19, P20 steel, alloy steel, and engineering metals in die & mould machining, aerospace components, automotive parts, and precision engineering applications.

Manufactured from premium micro-grain carbide rod, this tool provides excellent rigidity, wear resistance, and heat stability, enabling it to perform reliably at high spindle speeds in CNC machining centers. The optimized flute geometry ensures smooth chip evacuation, reduced cutting pressure, and minimal heat buildup, which helps prevent tool breakage and improves hole quality. This results in clean, burr-free holes with excellent straightness and dimensional accuracy.

With a 2.1 mm cutting diameter, D3 shank, 12 mm flute length, and 38 mm overall length, this micro drill offers an ideal balance between reach and stiffness. The D3 shank ensures strong tool holding with low run-out, which is essential for micro drilling accuracy and repeatability in CNC operations.

This tool is commonly used by CNC cutting tools manufacturers, industrial cutting tools suppliers, and precision carbide tools India markets for drilling mould inserts, injector parts, jigs, fixtures, and electronic components where tight tolerances are required. It supports high-speed CNC machining and batch production, providing longer tool life and consistent performance compared to conventional HSS drills.

The MICRODRILL 2.1×D3×12×38 (55 HRC) is suitable for VMCs, Swiss-type machines, and high-speed CNC spindles, ensuring stable drilling, minimal vibration, and superior hole quality. It is a reliable choice for workshops seeking solid carbide drills, carbide tools for 48–55 HRC materials, and precision cutting tools.
