Premium HSS Titanium-Coated Twist Drill Bit Set (13-Piece Set, 1.5–6.5mm)

The image shows a professional 13-piece high-speed steel (HSS) twist drill bit set housed in a heavy-duty, high-visibility red plastic index case. Each bit features a premium gold-toned titanium nitride (TiN) coating designed to reduce friction and heat, offering an exceptional value add for contractors, metalworkers, and DIY enthusiasts looking for clean, precision boring.

Technical Features & Performance Specifications

• Titanium-Coated High-Speed Steel (HSS): Engineered from professional-grade HSS with a premium titanium finish. This industrial coating significantly increases surface hardness, reduces thermal friction, and extends tool cutting life up to six times longer than standard black oxide bits.

• 13-Piece Precision Graded Set: Includes thirteen essential, incrementally sized drill bits organized cleanly in a stepped storage index:

  • Sizes Included: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, and 6.5mm.

• Industrial Manufacturing Standards: The storage case features standard engineering specification labels, highlighting compliance with HSS DIN 338 RN manufacturing protocols for precise flute geometry and straight tracking.

• Multi-Material Application Badges: The front of the case features clear visual performance icons demonstrating optimization for three major material categories:

  • Metal / Metalle: Clean penetration through sheet metal, alloy steels, and structural iron.

  • Alu: High-efficiency drilling through soft metals like aluminum and brass without chip clogging.

  • Wood / Holz: Fast, splinter-free hole boring through hardwoods, softwoods, and plywood composites.

Storage & Merchandising Design

• Heavy-Duty Index Case: Features an impact-resistant red plastic hardshell case equipped with a crystal-clear, high-visibility plastic viewing window to quickly check inventory.

• Easy-Read Size Gradients: The internal storage tray features bold, contrast-printed measurement indicators underneath each bit slot, ensuring swift tool identification and organization on the job.

• Integrated Hang Hook: Outfitted with a secure, black plastic integrated hanging tab at the top spine for clean retail display board or pegboard workshop storage.
