FANAR carbide drill bit 3.00 mm, 28/66 mm shank/reach, 5xD, HA6 VHM Blue Cut

FANAR carbide drill bit with a 3.00 mm cutting diameter and a 28/66 mm shank/reach specification is designed for precision drilling in metals and engineering materials. Manufactured from HA6 VHM grade solid carbide and finished with Blue Cut coating, this tool combines rigidity and wear resistance to maintain dimensional accuracy when drilling small-diameter, relatively deep holes. The 5xD length-to-diameter ratio provides a balance between reach and stiffness for fine machining tasks.

Advantages

The HA6 solid carbide substrate delivers high hardness and thermal stability for consistent cutting performance. Blue Cut coating improves surface hardness and reduces built-up edge, contributing to longer tool life and improved chip flow. The 5xD geometry and the specified shank/reach dimensions support accurate hole positioning and repeatable depth control while minimizing deflection during feed. The tool is suitable for use in CNC operations and precision drill fixtures where small-diameter accuracy is required.

Suitable for

• Precision through-holes and partial-depth holes in steel and non-ferrous metals
• Multistage machining and small-part production on CNC machines
• Toolroom and prototype drilling where tight tolerances are required
• Applications requiring improved chip evacuation and surface finish

How to use

Select appropriate spindle speeds and feed rates based on workpiece material and rigidity of the setup; consult standard cutting data for carbide drills as a starting point. Secure the workpiece and use a suitable collet or drill holder to minimize runout — the specified shank dimensions ensure proper clamping. Use coolant or appropriate cutting fluid when drilling steels or alloys to reduce heat and improve chip evacuation. For deep holes, peck drilling cycles or controlled withdrawal can help avoid chip packing and maintain hole quality.

Usage recommendations

For optimal tool life and hole accuracy, maintain low runout in the toolholder, use steady feed rates matched to material hardness, and employ through-coolant or external flood cooling when machining steels. Inspect holes for burrs and verify dimensions after machining to ensure repeatable results.
