Overview

Meet the GDLIN 230 Pcs Titanium Twist Drill Bit Set, built to handle metal, wood, and plastic with dependable performance. The kit includes 230 pieces across a broad size range from 3/64 in to 1/2 in, plus a lightweight plastic storage case that keeps everything organized and portable for on site or in the workshop.

• Double U shaped grooves actively remove chips to maintain cutting efficiency during longer drilling sessions.
• Titanium coated surfaces reduce wear and heat buildup for longer tool life and smoother cutting.
• Lightweight plastic storage box with a size index keeps bits organized, protected, and easy to transport.

What you get and how to use it

• 230 pieces across sizes 3/64 in to 1/2 in, with multiple bits per common size for quick task switching.
• Durable case with internal slots and index for fast size selection.

Practical guidance for best results

Whether you’re assembling furniture, drilling aluminum housings, or working with plastics, this bit set is designed to adapt to common projects. To maximize results, start with the closest fitting size, apply steady pressure, and allow the bit to do the work. For metal and hard plastics, use lower speeds to reduce heat and preserve the edge; for wood, a moderate feed helps prevent splintering and fade-free cuts.

• Chip clearing is aided by the double groove design, helping maintain cutting efficiency.
• Self centering geometry helps you begin holes with accuracy, reducing the need for additional guides.
