HSS Extra-Length Straight Shank Drill 12.50 mm – Somta Series 124
The SOMTA 1241250 – 12.50 mm HSS Extra-Length Drill is designed for deep-hole and extended-reach applications where standard drills are too short. Manufactured to ISO 3292 standards, this drill features a full-length straight shank and a long 250 mm overall body for accessing hard-to-reach drilling locations. The tool is made from high-performance High-Speed Steel (HSS) and treated with a blue oxide finish to minimize friction and enhance wear resistance. A 118° standard point ensures easy starts and reduced walking across steel, aluminum, and non-ferrous metals.
