Description
The Somta Parabolic Flute Jobber Drill, Uncoated, No.11, is a versatile general‑purpose drill bit designed to tackle a wide range of materials with dependable results. Its parabolic flute helps move chips away quickly, reducing cutting forces for smoother, more controlled drilling.
Designed for engineers, tradespeople, hobbyists, and maintenance professionals, this drill bit is suitable for stainless steel, alloy steels, cast iron, and non‑ferrous metals. The uncoated construction aids heat dissipation during drilling, which helps maintain bit life and consistent performance across demanding tasks.
- Parabolic flute for efficient chip evacuation: The parabolic geometry clears chips quickly, reducing heat and preventing clogging to keep you drilling smoothly through tougher materials.
- Uncoated construction for improved heat dissipation: With no coating to insulate heat, this drill bit stays cooler under load, extending life and enabling steady performance when drilling stainless steel and other hard metals.
- Sharp cutting edges for clean, precise holes: Ground to a sharp edge, this bit delivers clean holes with minimal burrs, finishing jobs faster and reducing secondary deburring.
No.11 size provides versatile capability for a wide range of standard drilling applications, helping you complete projects efficiently with reliable, consistent results across common metals.
