Applications for
Haas Tooling

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.

Key Products
from Haas Tooling

Inox Series

Overview

The Inox Series is a line of solid carbide drills engineered for machining stainless steel and pre-hardened steels.

Specially designed flutes and chip pockets maintain optimal chip curl, while robust cutting edges prevent chipping. The TiAlN coating provides excellent wear resistance and low friction, ensuring stable and consistent cutting performance.

A combination of a 140° point angle, positive axial rake, and radius thinning enhances self-centering capability and chip control. When used with through-spindle coolant, the drill maintains high stability even during extended continuous operation.

Compatible Materials

• Steel
• Stainless steel
• Non-ferrous metals
• Hard-to-cut materials

Lineup

• 5xD

General Purpose Series

Overview

The General Purpose Series is a versatile line of solid carbide drills designed for general holemaking in steel and cast iron.

A TiAlN coating delivers excellent wear resistance and low friction, ensuring stable performance even under high-speed, high-feed conditions.
The 140° point angle and wave-shaped cutting edges reduce cutting resistance, enabling smooth torque and consistent drilling.

In addition, radius thinning improves self-centering and chip breaking, while the optimized flute geometry and negative land contribute to extended tool life.

Compatible Materials

• Steel
• Stainless steel
• Cast iron
• Hard materials

Lineup

• 3xD
• 5xD
• 8xD

Aluminum Series

Overview

The Aluminum Series features optimized point thinning that improves bite and prevents clogging, while its ultra-low-friction DLC coating and mirror-polished flutes minimize chip adhesion and built-up edge formation.

The DLC coating effectively suppresses built-up edge, maintaining sharp cutting action. When used in combination with through-spindle coolant, the drill delivers high-quality holes with excellent roundness, straightness, and surface finish.

Compatible Materials

• Non-ferrous metals

Lineup

• 5xD
