Somta Jobber Drills Parabolic Flute - UnCoated - 4.9mm

The Somta Parabolic Flute Jobber Drills Uncoated, 4.9 mm, are general-purpose drill bits designed for everyday metalworking, fabrication, and workshop tasks. The parabolic flute design helps move chips away quickly, reducing cutting forces and delivering smooth, controlled starts for reliable hole quality.

With an uncoated body, these drills dissipate heat more effectively, expanding their versatility across a wide range of materials—from stainless steel and alloy steels to cast iron and non-ferrous metals. The sharp cutting edges produce clean holes with minimal burrs, helping you reduce finishing work and speed up production.

• Parabolic flute design for smooth drilling and efficient chip evacuation: The shape channels chips away from the cutting edge, lowers cutting resistance, and supports steadier starts for consistent hole quality.
• Uncoated construction for improved heat dissipation: Without coating, heat travels away from the tip more efficiently, helping protect the cutting edge on hard materials and across a broad material range.
• Sharp edges for clean, burr-minimized holes: Precise, sharp cutting edges deliver accurate holes with minimal burrs across stainless steel, alloy steels, cast iron, and non-ferrous metals.

This drill bit is built to support reliable, high-quality results in busy shops and on job sites. It reduces downtime by delivering clean holes on the first pass, improves workflow with easier chip clearance, and provides the durability needed for repeated use across a variety of metals. Whether you're building, repairing, or prototyping, this 4.9 mm parabolic flute drill helps you finish jobs faster with fewer reworks.
