Tungaloy Corporation offers solid carbide drills that meet the demands of both high-volume cast iron machining and precision deep-hole drilling at ultra-small diameters.
This article introduces Tungaloy’s two main drill series—the Solid4FlutesDrill and SolidDrill (DSW, DSM)—highlighting their features, product lineups, and advantages in efficiency, tool life, and cost performance.

Tungaloy's drills are ideal for manufacturers in the automotive, aerospace, medical device, and precision parts industries—especially those aiming to reduce tooling costs, inventory management workload, and setup changeover time.
With support for a wide variety of materials and hole depths, each series is designed to minimize tool changes and reduce the number of tool types required in production.
Note: Performance may vary depending on cutting speed, feed rate, coolant, and machine rigidity.
The Solid4FlutesDrill series is engineered for high-efficiency, high-precision drilling, particularly in high-volume production of cast iron parts for automotive and construction machinery.
Key Features:
The SolidDrill series offers stable tool life while minimizing wear and chipping across a wide range of materials, including steel and stainless steel.
The series includes two product types—DSW and DSM—each tailored to different machining needs.
DSW covers medium-diameter drilling (Ø3–12 mm). It features a new coating material and specially designed cutting edge geometry to reduce cutting resistance and enable stable drilling. The series includes both external coolant (DE) and internal coolant (DI / CI) types, providing flexible options depending on machine capabilities and hole depth requirements.
DSM, on the other hand, is designed for ultra-small diameter and deep-hole drilling starting from Ø0.1 mm. It offers sizing in 0.01 mm increments and includes center drill models that prevent misalignment at hole entry. This makes it ideal for high-precision applications in fields such as electronics, medical devices, and fine component manufacturing.
