VHM 3 x 18 x 38 Z-3 HA End mill; finish; uncoated; Long

VHM end mill with a 3 mm cutting diameter, 18 mm length of cut, and 38 mm overall length, set up as a Z-3 (3-flute) cutter. The HA shank style keeps the holding side consistent and predictable in the toolholder, and the “Long” size points to extra reach compared to a short or standard variant.

Marked for finishing work (“finish”), so in practice you’d typically run it for final passes where edge quality and dimensional control matter more than maximum stock removal. Being uncoated means you’re relying on the base tool surface as-is—nothing unusual there, just keep an eye on heat and chip evacuation, especially with a 3 mm diameter where conditions can change quickly if the cut gets crowded.

With the 18 mm cutting length, you’ve got enough flute to handle deeper wall work within that range, while the 38 mm total length keeps the tool compact enough for stable finishing when the setup is reasonable.

Key Features

• Tool type: End mill (VHM)
• Dc: 3 mm cutting diameter
• Lc: 18 mm length of cut
• Lt: 38 mm overall length
• z (Z-3): 3 flutes
• Shank: HA
• Surface: finish
• Coating: uncoated
• Size: Long

Applications

• Finishing passes where a cleaner surface and controlled final dimensions are the priority
• Jobs needing a long-reach 3 mm, 3-flute end mill within an 18 mm cutting length

Recommendations

• Match the holder to the HA shank style and keep runout under control for best finish
• Because it’s uncoated, monitor heat and adjust feed/speed conservatively if needed
