Frequently Asked Questions

Q: What type of drill or tool do these 1mm carbide bits fit?

A: These drill bits have a 1.5mm shank diameter, making them compatible with most rotary tools, pin vises, and precision hand drills that accept small-shank bits. Always ensure your tool's collet can securely grip a 1.5mm shank before use.

Q: Can these carbide drill bits be used on tempered glass?

A: These bits are designed for use on laminated auto glass (standard windshields) as part of a chip or crack repair process. They are not recommended for drilling into tempered glass (side or rear windows), as tempered glass will shatter when penetrated. Always use them carefully and only on the appropriate glass layer.

Q: How many uses can I expect from each drill bit?

A: Due to their high-hardness carbide alloy construction and heat-treated design, each bit is built for durability and multiple uses. Longevity depends on technique and glass hardness, but the 4-pack ensures you have backups on hand for uninterrupted work sessions.

Q: Are these suitable for DIY windshield repair kits?

A: Yes! These bits are ideal for use alongside standard windshield repair resin injection kits. Use them to carefully clean and open the damaged area before applying resin for a cleaner, more professional-looking result.
