It falls between the 1-inch and 1 1/4-inch drill bits, making it suitable for a wide range of tasks. The bit’s diameter is slightly larger than the standard 1-inch bit, which allows for more material to be removed in each pass, resulting in faster drilling times.

Materials Suitable for Drilling with a 1 1/8 Drill Bit

The 1 1/8 drill bit is versatile and can be used to drill holes in a variety of materials. Here are some common materials where this bit excels:

As you can see from the table, the 1 1/8 drill bit performs well in both soft and moderately hard materials. However, it’s important to note that the drilling speed and feed rate may vary depending on the material being worked on.

Benefits of Using a 1 1/8 Drill Bit

There are several advantages to using a 1 1/8 drill bit for your drilling projects:

• Increased Efficiency: The larger diameter of the bit allows for faster drilling times, especially when working with softer materials like wood and plastic.
• Reduced Hand fatigue: The larger bit size requires less force to drill through materials, reducing hand fatigue and strain.
• Improved Accuracy: The 1 1/8 drill bit is designed to provide precise hole drilling, ensuring that your holes are clean and well-aligned.
• Cost-Effective: Using a single bit for multiple applications can save you money in the long run, as you won’t need to purchase multiple bits for different tasks.
