Somta Jobber Drills Parabolic Flute - UnCoated - No.22

The Somta Parabolic Flute Jobber Drill, Uncoated, No.22, is a versatile general‑purpose drill bit designed for a wide range of metals and everyday drilling tasks. Its parabolic flute geometry helps chips evacuate quickly and reduces cutting forces, delivering smoother, more reliable drilling in typical workshop applications.

Because the drill is uncoated, heat is dissipated more efficiently during cutting, expanding its versatility across stainless steel, alloy steels, cast iron, and non‑ferrous metals. The No.22 size is ideal for starting holes, creating precise pilot holes, or when a smaller entry diameter is needed.

• Parabolic flute design for efficient chip evacuation: The flute geometry channels chips away from the cutting edge, reducing heat buildup and cutting forces for smoother starts and steadier performance.
• Uncoated construction for broad material compatibility: Without coating, heat dissipates quickly, enabling stable, consistent drilling in a wide range of metals—from stainless steels to cast iron and non‑ferrous alloys.
• Sharp, durable cutting edges for clean holes: Precision-ground edges maintain sharpness for clean entrances with minimal burrs and tight hole diameters, improving downstream fits and finishes.

This drill delivers dependable performance across everyday fabrication, maintenance, and workshop projects. It helps you reduce downtime from chip buildup and tool wear, supports accurate hole size and finish, and provides reliable results job after job, making it a trusted choice for engineers, machinists, and DIYers alike.
