Applications
for Speed Tiger

Speed Tiger tools are suited for metalworking environments that require consistent performance and predictable tool life in stainless steels, alloy steels, and other heat-generating materials. The brand’s stainless-focused carbide drills are especially relevant for production lines that need stable hole straightness, consistent surface finish, and reliable chip evacuation across multiple shifts.

Target industries include aerospace, automotive, medical device manufacturing, general engineering, job shops, and mold and die support. For stainless steel drilling, the right combination of drill geometry and coating can help reduce cycle time and lower cost per hole when matched to machine rigidity, coolant strategy, and workholding conditions.

How to Choose Carbide Drills
from Speed Tiger

For Stainless Steel Drilling

Recommended Series: SN Carbide Drill for Stainless Steel 3xD / 5xD

For stainless steel drilling where chatter control, chip evacuation, and hole accuracy matter, Speed Tiger’s SN Carbide Drill for Stainless Steel series is the primary choice.

The SN series is designed for stable stainless steel machining, using asymmetrical irregular margins for smoother hole surfaces and precise cutting, along with unequal flute spacing to help reduce chatter and improve chip evacuation.

The lineup includes non-coolant-hole versions for 3xD and 5xD drilling, plus coolant-hole versions for more demanding 5xD and 8xD applications. This lets buyers choose based on drilling depth, coolant strategy, and production requirements.

Speed Tiger’s PVD Coating (ZrN-A) supports high-speed stainless steel machining in both dry and wet cutting, with published characteristics including 2800–3000 HV hardness, a 0.3 coefficient of friction, and an 800–900°C oxidation temperature.

Best Fit Applications

• Stainless steel drilling where chatter control is important
• 3xD and 5xD drilling without coolant holes
• 5xD and 8xD drilling where coolant-hole designs are preferred
• Applications requiring smoother drilling surfaces and accurate straight cutting
• High-speed dry or wet cutting in stainless-focused production environments

Available 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

For Positioning Before Drilling

Recommended Series: PDST Position Drill - 2 Flutes

For applications that require accurate tool entry before drilling, Speed Tiger’s PDST Position Drill is designed for spotting and positioning operations.

This 2-flute carbide tool helps improve hole-location repeatability before the main drilling process. For shops using carbide drills, it can support more consistent starts and reduce positioning error.

The series is available in uncoated and ZrN-A coated versions, giving buyers options based on work material, cutting speed, and coolant strategy. For stainless steel applications, the ZrN-A coating supports lower friction, better heat resistance, and more stable performance at higher surface speeds.

Published ZrN-A characteristics include 2800–3000 HV hardness, a 0.3 coefficient of friction, and an 800–900°C oxidation temperature.

Best Fit Applications

• Spot drilling before the main drilling process
• Positioning operations where hole-location accuracy matters
• Applications requiring improved tool entry and positional repeatability
• Stainless-focused setups where lower friction and heat resistance are useful
• Production workflows that need more consistent hole starts before carbide drilling

Available Lineup

• PDST Position Drill (2 Flutes)
  • Diameter range: Ø3–20 mm
  • Tip angle options: 90° / 120°
  • Coating options: Uncoated / ZrN-A
  • Models (Diameter × Flute Length × Overall Length / Shank Dia.)
