Somta Extra Long Series Drill - HSS-E Parabolic Flute - 14mm x 380mm

Meet the Somta Extra Long Series Drill - HSS-E Parabolic Flute, a purpose-built solution for deep hole drilling that demanding projects rely on. With a 14 mm cutting diameter and an impressive 380 mm overall length, this drill bit reaches into recessed workpieces and tight cavities where standard bits simply can’t go. Built for reliability, it combines long reach with precision performance to deliver true holes from start to finish.

Key features you’ll notice in every cut:

• HSS-E construction for enhanced durability and heat resistance, extending tool life under tough drilling conditions.
• Parabolic flute design optimizes chip evacuation, helping prevent clogging and maintaining steady cutting action even in challenging materials.
• Sharp cutting edges that produce clean, accurate holes with minimal finishing work.
• Extra-long geometry provides extended reach for deep holes, long workpieces, and setups with limited access.

Why this matters in real-world work:

• Machinists and fabricators tackling long, deep features in steel, cast iron, or other alloys will appreciate the ability to drill without repositioning the workpiece.
• In assembly lines and maintenance shops, the extra length reduces setup time and minimizes the need for multiple tools when accessing recessed components.
• For precision-focused tasks, the combination of parabolic flute and sharp edges translates to smoother holes and less subsequent deburring.

Practical use guidance to get the most from your Somta Extra Long Series Drill:

• Use a conservative feed rate and adequate lubrication to manage heat buildup during deep drilling.
• Maintain steady, perpendicular alignment to the workpiece to ensure true holes and prevent wobble in the tool path.
• When approaching the full 380 mm reach, support the workpiece adequately to avoid deflection and ensure hole accuracy.
