Speed Tiger

Founded in 1998, Speed Tiger Precision Technology Co., Ltd. has grown into one of Taiwan’s largest carbide cutting tool manufacturers, supplying high-performance CNC tooling to a global market. The brand is recognized for combining toolmaking with coating know-how early on, and today supports customers through a broad portfolio that includes precision carbide drills designed for demanding stainless applications.

For stainless Carbide Drills, Speed Tiger emphasizes stability under heat and work-hardening conditions through PVD coating technology and geometry optimized for chip control. Tools such as the SN stainless drill series apply the company’s ZrN-A coating concept—engineered for high-speed drilling in stainless with reduced friction and improved oxidation resistance—to help maintain consistent hole quality in production environments.

Beyond tool geometry and coatings, Speed Tiger highlights manufacturing capability and process control, including advanced grinding equipment and a strict inspection workflow designed to deliver stable, repeatable cutting performance from batch to batch. The company also positions its product development around practical machining needs—supporting both standard catalog tools and application-driven customization for specialized operations.

Applications
for Speed Tiger

Speed Tiger tools are commonly selected for metalworking environments where stainless steels, alloy steels, and heat-generating materials demand consistent performance and predictable tool life. In particular, the brand’s stainless-focused carbide drills are suitable for production lines seeking stable hole straightness, consistent surface finish, and repeatable chip evacuation across multiple shifts.

Target industries typically include Aerospace (stainless components and structural parts), Automotive (stainless fixtures, sensors, and assemblies), Medical (stainless surgical and device components), General Engineering and Job Shops (mixed-material production), and Mold & Die support operations. For stainless drilling programs, geometry and coating choices can support cycle-time reduction and lower cost per hole when matched to the machine’s rigidity, coolant strategy, and workholding conditions.

SN Carbide Drill For Stainless Steel 3xD / 5xD (3SN, 5SN, 5SNC, 8SNC)

Overview

The SN stainless drill series is designed for stable drilling in stainless steel with geometry that targets vibration control and hole accuracy. Key design points include dissymmetrical irregular margins to support smoother drilling surfaces and high-precision straight cutting, plus unequal flute spacing intended to reduce chatter and enhance chip removal. A 135° point angle is used for the stainless-focused variants, and the lineup includes both versions without coolant holes (3SN, 5SN) and with coolant holes (5SNC, 8SNC) for higher-demand drilling strategies.

For stainless programs, Speed Tiger’s PVD Coating (ZrN-A) is presented as a “block resistance” coating suitable for high-speed machining in dry and wet cutting. The published coating characteristics include hardness 2800–3000 HV, low coefficient of friction (0.3), and oxidation temperature 800–900°C, supporting thermal stability when drilling work-hardening stainless grades.

Lineup

• 3SN: 3xD, without coolant hole, helix angle 30°, point angle 135°, coating ZrN-A, diameter range Ø3.0–16.0 mm
• 5SN: 5xD, without coolant hole, helix angle 30°, point angle 135°, coating ZrN-A, diameter range Ø3.0–14.0 mm
• 5SNC: 5xD, with coolant hole, helix angle 28–30°, point angle 140°, coating ZrN-A, diameter range Ø3.0–14.0 mm
• 8SNC: 8xD, with coolant hole, helix angle 28–30°, point angle 140°, coating ZrN-A, diameter range Ø3.0–12.0 mm

PDST Position Drill - 2 Flutes

Overview

The PDST Position Drill is a 2-flute carbide tool built for spot/positioning operations prior to drilling, supporting accurate tool entry and improved positional repeatability. The series is offered in uncoated and ZrN-A coated variants, allowing selection based on work material and coolant strategy. For stainless-focused setups, the ZrN-A option is positioned to provide lower friction and better heat resistance under higher surface speeds.

Speed Tiger’s ZrN-A coating data highlights suitability for high-speed dry or wet cutting and stainless machining, with published characteristics including hardness 2800–3000 HV, coefficient of friction 0.3, and oxidation temperature 800–900°C. In practical terms, this can support cleaner tool entry and more stable performance when positioning on stainless surfaces that tend to work harden.
