KWB 13 mm DIN 338 HSS Twist Drill Bit for Metal Right Hand Rotation

The KWB 13 mm DIN 338 HSS Twist Drill Bit for Metal Right Hand Rotation is a precision-engineered tool designed for accurate and efficient metal drilling applications. Manufactured according to DIN 338 standards, this roll-forged twist drill bit features a type N fluting and a blue-black steam-hardened surface finish that helps reduce wear during extended use. With a 13 mm diameter and a reduced shank, it is specifically designed to fit standard electric drills with compatible chuck capacities, making it a reliable addition to any professional workshop or DIY tool collection.

Advantages

This HSS twist drill bit delivers reliable performance thanks to its robust construction and standard 118-degree tip angle, which ensures steady centering upon contact with the workpiece. The right-hand cutting direction provides smooth chip evacuation and consistent operation across a variety of materials. Its reduced shank design allows users to drill larger diameters using standard power tools without requiring specialized heavy-duty equipment. The steam-hardened blue-black finish adds durability and helps maintain cutting edge integrity over multiple applications.

Suitable for

• Drilling alloyed and mild steel
• Working with cast iron and metal castings
• Drilling non-ferrous metals
• Working with hard plastics and plastic profiles
• Drilling sheet metal

This drill bit may not be suitable for heavy industrial high-speed production environments where specialized cobalt or carbide multi-flute tooling is required. It is also not intended for drilling masonry, concrete, or natural stone.

Before beginning any drilling task, ensure that the workpiece is securely clamped and that you are wearing appropriate personal protective equipment such as safety glasses. Insert the reduced shank firmly into the drill chuck and tighten it securely. Select an appropriate drilling speed matching the material being processed, and apply steady, moderate pressure without forcing the tool to prevent overheating or bit breakage. For optimal results when working with metals, use a suitable cutting fluid or lubricant.

What to consider before purchase

• Verify that your power drill chuck is compatible with the 13 mm diameter and reduced shank design
• Check that the material you plan to drill matches the compatible surfaces such as steel, non-ferrous metals, or plastics
• Ensure you have appropriate cooling lubricants for metal drilling applications

Always allow the drill bit to cool down naturally after intensive use and store it in a dry place to prevent corrosion and maintain cutting performance.
