## Long description

The Irwin 10502545 is a professional-grade twist drill bit with a 3.3 mm diameter, specifically engineered for high-performance drilling in demanding materials. Designed to meet DIN 338 standards, this tool features a robust construction that ensures stability and precision during operation. Its specialized geometry and material composition allow for efficient material removal, making it a reliable choice for both industrial metalworking and precise DIY projects.
Advantages
This drill bit is manufactured with a 5% cobalt alloy, which significantly enhances its resistance to heat and abrasion when working with tough materials. The heavy-duty web construction provides superior strength, preventing breakage under pressure. Additionally, the 135-degree split point design ensures that the bit begins drilling immediately upon contact, effectively minimizing walking on the surface and allowing for highly accurate hole placement.
Suitable for
Drilling into alloyed steel
Working with stainless steel
General metal fabrication tasks
Precision drilling in hardened or heat-treated metals
This drill bit may not be suitable for drilling into soft materials like wood or plastic, as the high-cobalt composition is optimized for metal hardness rather than wood-boring efficiency. It is also not intended for use in masonry or concrete applications, as the cutting edge is designed specifically for metal alloys.
Key specifications
Type: Twist drill bit
Diameter: 3.3 mm
Total length: 65 mm
Material composition: 5% Cobalt HSS
Shank type: Cylindrical
Point angle: 135-degree split point
To use this drill bit, ensure it is securely fastened in a compatible drill chuck. Align the 135-degree split point with your marked center point and apply steady, consistent pressure. It is recommended to use a lower drilling speed when working with hardened metals to prevent overheating and to maintain the integrity of the cutting edge. Using a suitable cutting fluid can further extend the life of the bit and improve the quality of the hole.
What to consider before purchase
Verify that your drill chuck supports a 3.3 mm cylindrical shank.
Ensure the material you are drilling is compatible with cobalt-grade steel.
Consider the depth of the hole, as this bit is designed for standard drilling lengths.
For optimal results and to prevent premature wear, always maintain a steady feed rate and use appropriate cooling lubricants when drilling into stainless or hardened alloy steels.
