Description
Product Overview
The LLDSIMEX 60‑piece titanium nitride coated drill bit set is engineered for professionals and serious hobbyists who demand precision, durability, and versatility in a single compact package. Each bit is forged from high‑speed steel (HSS) and treated with a titanium nitride coating that reduces friction, extends tool life, and provides a bright gold finish that resists corrosion. The set spans sizes #1 through #60, covering wire gauge equivalents from 0.228″ down to 0.040″, which translates to a practical range for drilling holes in wood, metal, and plastic. The bits feature a 118° standard point geometry and a straight shank design that fits securely into most power drills and hand‑drill presses, delivering clean, accurate holes with minimal wobble. The included metal indexed storage case is engineered with individual slots for each size, ensuring quick identification and easy access on the job site or in a workshop. ![[Product front view showing all components]](https://www.ualvora.store/wp-content/uploads/2026/08/2a8bc8c51f5e465e9a0a104dbc2adb8d.jpg)

FAQ
What materials can these drill bits safely drill?
The titanium nitride coated bits are suitable for drilling wood, soft and hard metals, as well as various plastics such as PVC, acrylic, and polycarbonate. The coating helps reduce heat and wear, making the bits versatile across these material types.
How does the titanium nitride coating affect performance?
The coating creates a low‑friction surface that minimizes heat buildup during drilling, which in turn reduces the chance of bit dulling or workpiece damage. It also provides a protective barrier against corrosion, extending the usable life of each bit.
Is the set compatible with cordless drills?
Yes. All bits feature a straight shank that fits standard 1/4″ to 1/2″ chucks found on most cordless and corded drills, as well as drill presses. This universal fit ensures you can use the set with the tools you already own.
What is the warranty coverage for this drill bit set?
LLDSIMEX offers a one‑year limited warranty covering manufacturing defects. If a bit fails due to a defect within the warranty period, contact customer support for a replacement or refund.
How should I maintain the bits to maximize their lifespan?
After each use, clean the bits with a soft brush to remove debris, and store them in the provided indexed case. Avoid exposing the bits to extreme moisture or chemicals, and periodically inspect the coating for wear. Proper care will help maintain cutting performance for years.
