Somta Series 134 – 15/32″ HSS Extra Length Straight Shank Drill

Somta Series 134 – 15/32″ HSS Extra Length Straight Shank Drill (Blue Finish) | 1341191

The SOMTA 1341191 is a 15/32″ High-Speed Steel Extra Length Straight Shank Drill developed for deep-hole drilling applications where superior reach, rigidity, and accuracy are essential. Built to ISO 3292 / DIN 1869 standards, it ensures excellent concentricity, hole finish, and tool stability across a wide range of engineering materials. The blue-oxide finish enhances lubrication, reduces friction, and resists heat build-up for prolonged tool life.

Ideal for metal fabrication, maintenance, and production environments requiring deep, precise holes in ferrous and non-ferrous materials.

Key Features & Benefits
