New Addition to Our Indexable Drills Family!

Indexable drills are typically used for roughing and semi-finishing holes with diameters ranging from φ12.0 to φ80.0 and depths within 5×D. Compared to solid carbide drills, they offer higher cost efficiency, and compared to HSS twist drills, they deliver superior machining productivity. These tools are widely applied in industries such as automotive, energy, construction machinery, valves, molds, and general manufacturing.To meet customers' high-performance demands in steel machining, GESAC has launched a new generation of high-performance shallow hole drills for steel applications—featuring a differentiated cutting edge design (internal vs. external).

Specifically engineered for:

◊ Low-speed, high-feed conditions – Stable machining under specialized parameters
◊ High surface finish requirements – Improved hole wall roughness for quenched/tempered steels and mild steels
◊ Extended continuous machining – Enhanced tool life for prolonged operations
◊ Cost-sensitive applications – Near-imported-brand performance at a more competitive price

The new series serves as a strategic complement to existing products in steel machining applications.
