IRWIN 10502397 twist drill bit for wood with a 10 mm diameter, cylindrical shank

The IRWIN 10502397 twist drill bit for wood with a 10 mm diameter and cylindrical shank is a reliable tool engineered for precise and clean drilling performance in various workshop and home improvement scenarios. Manufactured to DIN 338 standards, this twist drill bit incorporates a universal 118-degree point shape that ensures stable centering and effective penetration across multiple material types. The precision ground cutting edges facilitate fast drilling speeds and deliver a clean finish, minimizing splintering and material tear-out. Additionally, the ground flute design promotes maximum drilling accuracy and efficient chip removal, ensuring smooth operation during extended use.

Advantages

This drill bit delivers exceptional performance through its precision-ground cutting edges which enable fast drilling and an immaculate final finish on the work surface. The integrated ground flute configuration optimizes chip evacuation, significantly reducing clogging and heat buildup during continuous operation. Built to DIN 338 standards, it offers consistent quality, dependable durability, and structural integrity for repetitive tasks. Its universal 118-degree point shape allows for versatile application across different materials without requiring frequent tool changes, while the standard cylindrical shank ensures broad compatibility with most common power drills and drill presses.

Suitable for

• Woodworking and carpentry projects
• Drilling clean holes in soft metals
• Working with plastic sheets and components
• DIY home improvement and furniture assembly

When it may not be suitable

This drill bit is not designed for heavy-duty industrial masonry applications, concrete, or reinforced stone drilling. It should also be avoided when working with hardened structural steels that require specialized high-cobalt or carbide-tipped tooling.

Key specifications

• Twist drill bit design
• Drill bit diameter: 10 mm
• Cylindrical shank
• Length: 133 mm
• Universal 118-degree point shape
• Manufactured to DIN 338 standards
• Single-piece package

How to use

Secure the cylindrical shank firmly into the chuck of your power drill or drill press to ensure concentric rotation during operation. Align the 118-degree drill point perpendicular to the marked surface of the wood, plastic, or soft metal workpiece. Apply steady, moderate axial pressure while maintaining a controlled rotational speed, allowing the precision ground cutting edges and flute to remove material effectively. Avoid excessive lateral pressure to prevent bit bending or breakage, and periodically clear accumulated chips when drilling deeper holes.

What to consider before purchase

• Verify that your drill chuck accommodates a 10 mm cylindrical shank diameter
• Confirm the 133 mm total length is suitable for your specific application depth
• Check that the targeted materials match the wood, plastic, and soft metal compatibility

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses, when operating drilling tools. Secure the workpiece firmly with clamps to prevent movement during the drilling process and avoid premature bit wear by matching the drill speed to the material being processed.
