The Irwin 10502394 twist drill bit is a precision-engineered tool designed for reliable performance in a variety of drilling applications. With a diameter of 8.5 mm and a total length of 117 mm, this drill bit is manufactured to meet DIN 338 standards, ensuring consistent quality and dimensional accuracy. Its robust construction and ground flute design facilitate efficient material removal, resulting in clean, precise holes every time.

Advantages

This drill bit features precision-ground cutting edges that allow for fast drilling speeds and a high-quality finish on the workpiece. The universal 118-degree point angle makes it highly versatile, enabling it to perform effectively across a wide range of materials. The ground flute design is specifically engineered to maximize accuracy and ensure rapid chip evacuation, which prevents clogging and overheating during extended use.

Suitable for

• Drilling into wood
• Working with soft metals
• Boring holes in plastic materials
• General professional and DIY construction tasks

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, masonry, concrete, or stone. Using it on these materials will lead to rapid dulling of the cutting edges and potential damage to the tool.

Key specifications

• Type: Twist drill bit
• Diameter: 8.5 mm
• Total length: 117 mm
• Shank type: Cylindrical
• Point angle: 118 degrees
• Standards: DIN 338

How to use

To use the Irwin twist drill bit, insert the cylindrical shank into the chuck of your power drill or drill press and tighten it securely. Ensure the workpiece is properly clamped to prevent movement during the drilling process. Begin drilling at a moderate speed, applying steady, even pressure. Allow the drill bit to do the work, and periodically retract the bit to clear away accumulated chips, especially when drilling deeper holes.

What to consider before purchase

• Verify that your drill chuck is compatible with the 8.5 mm cylindrical shank.
• Ensure the material you intend to drill is suitable for this specific bit type.
• Check if the 117 mm length is sufficient for the depth of the holes required for your project.

Usage recommendations

For optimal results and to extend the lifespan of the drill bit, use a suitable cutting lubricant when drilling into soft metals and maintain a consistent feed rate to avoid overheating the tip.
