For manufacturers in the automotive and aerospace industries who face challenges such as limited cutting efficiency, inconsistent tool life, and high defect rates, Haas Tooling offers a reliable solution.
This article compares Haas Tooling’s carbide drill series, highlighting recommended models by material type—including those designed for through-spindle coolant—and explains how they help improve hole quality and machining stability.

Haas Tooling’s carbide drills are ideal for high-volume production environments where reducing the cost per part is a key priority.
Each drill is engineered based on in-house cutting tests conducted at Haas’s own facilities. They feature wear-resistant coatings such as TiAlN and DLC, and are available in models compatible with through-spindle coolant systems that deliver coolant directly to the cutting edge.
This configuration minimizes tool wear and chip clogging, extending tool life and reducing machine downtime.
In particular, the Inox Series, developed specifically for stainless steel and other hard-to-cut materials, delivers exceptional stability and long-lasting performance under demanding machining conditions.
Note: Performance may vary depending on tool type, cutting speed, feed rate, coolant type, and machine rigidity.
As a carbide drills manufacturer and tooling supplier, Haas Tooling offers solid carbide drill series designed for different material groups, including stainless steel, general steels, cast iron, and aluminum. The right choice depends on the workpiece material, drilling depth, coolant availability, and the balance required between chip control, wear resistance, and hole quality.
Inox Series
Choose the Inox Series when drilling stainless steel or pre-hardened steels, where chip control, edge strength, and stable cutting performance are especially important. This series is designed to maintain consistent performance in materials that can be difficult to machine due to heat generation, work hardening, or chip control issues.
Specially designed flutes and chip pockets help maintain optimal chip curl, while robust cutting edges reduce the risk of chipping. The TiAlN coating provides wear resistance and low friction, supporting stable performance during continuous machining.
A 140° point angle, positive axial rake, and radius thinning improve self-centering capability and chip control. When used with through-spindle coolant, the drill can maintain high stability during extended operation.
General Purpose Series
Choose the General Purpose Series when the application requires reliable carbide drilling in common materials such as steel and cast iron. This series is a practical option for general holemaking where consistent performance, tool life, and productivity are required across standard machining conditions.
The TiAlN coating provides wear resistance and low friction, helping the drill perform under high-speed and high-feed conditions. A 140° point angle and wave-shaped cutting edges help reduce cutting resistance, supporting smooth torque and stable drilling.
Radius thinning improves self-centering and chip breaking, while the optimized flute geometry and negative land contribute to longer tool life. With 3×D, 5×D, and 8×D options, this series can support a range of standard drilling depths.
Aluminum Series
Choose the Aluminum Series when drilling aluminum or other non-ferrous metals, where chip adhesion, built-up edge, and chip clogging can affect hole quality. This series is designed to support clean cutting and smooth chip evacuation in materials that tend to stick to the cutting edge.
Optimized point thinning improves bite and helps prevent clogging, while the ultra-low-friction DLC coating and mirror-polished flutes minimize chip adhesion and built-up edge formation.
When used with through-spindle coolant, the Aluminum Series can produce high-quality holes with strong roundness, straightness, and surface finish.
