Somta Jobber Drills Parabolic Flute - UnCoated - No.58

The Somta Parabolic Flute Jobber Drills Uncoated (No. 58) are versatile general‑purpose drill bits designed for everyday metalworking and fabrication tasks. The parabolic flute promotes efficient chip evacuation and reduces cutting forces for smoother, more consistent holes. With an uncoated finish that improves heat dissipation, these bits perform across stainless steel, alloy steels, cast iron, and non‑ferrous metals, delivering clean holes with minimal burrs.

• Parabolic flute design for smooth drilling: The parabolic flute geometry channels chips away from the cutting edge, reducing thrust and producing steadier holes during drilling across materials.
• Uncoated construction for better heat dissipation: The uncoated surface helps dissipate heat more effectively, extending tool life and enabling reliable performance in a wide material range.
• Sharp, burr-minimized cutting edges: Precisely ground edges deliver clean holes with minimal burrs, reducing finishing work and improving hole quality.

This No. 58 Somta parabolic drill helps you complete projects faster and with fewer reworks. The efficient chip evacuation and heat management mean you can push through tougher metals with less downtime, while the broad material compatibility minimizes the need for multiple tool types. The result is precise, burr-free holes and consistent performance across a variety of tasks—giving you reliable tooling you can depend on for everyday manufacturing, maintenance, or workshop projects.
