Description
The Somta Parabolic Flute Jobber Drill, Uncoated, 3.3 mm is a versatile general‑purpose drill designed for a wide range of materials and everyday drilling tasks. Its parabolic flute geometry promotes rapid chip evacuation and lowers cutting forces, delivering smoother, more controlled drilling for dependable results.
With an uncoated construction, this drill bit offers excellent heat dissipation, making it well-suited for stainless steel, alloy steels, cast iron, and non-ferrous metals. The sharp cutting edges help produce clean, precise holes with minimal burrs, reducing finishing time and improving overall hole quality.
- Parabolic flute design for efficient chip evacuation: Chips are expelled quickly from the cutting zone, reducing cutting forces and heat buildup for smoother, more stable drilling across a variety of materials.
- Uncoated construction for enhanced heat dissipation: Absence of coating allows heat to dissipate more effectively, helping maintain tool life and consistent performance on hard metals like stainless steel and alloy steels.
- Sharp cutting edges for clean, precise holes: Delivers accurate hole sizes with minimal burrs, reducing post-drilling finishing work and improving hole quality for reliable assemblies.
In everyday shop use, this drill bit supports faster throughput, fewer interruptions, and dependable results across mixed-material projects. The 3.3 mm diameter is ideal for precise pilot holes or through-holes, and the combination of parabolic flute and uncoated geometry helps you finish tasks with confidence and professional-grade quality.
