The KWB 421103 is a single 3 mm twist drill bit made of high-speed steel (HSS), engineered for right-hand rotation. Unlike generic bits, it is supplied in a clear blister pack that keeps the bit protected and visible, making it easy to identify the size at a glance. The cylindrical shank fits standard drill chucks, and the DIN 338 design ensures a precise, concentric point for accurate hole starting.

Highlights

• 3 mm diameter twist drill bit for general-purpose drilling
• High-speed steel (HSS) construction for durability and heat resistance
• Right-hand rotation direction, suitable for standard drills
• Blister pack packaging for secure storage and easy identification
• Versatile across metal, plastic, and wood

In daily use

This bit is a practical choice for workshop and DIY tasks where a clean 3 mm hole is needed. The HSS material holds an edge longer than carbon steel bits, and the twist flute design clears chips efficiently to reduce binding. Use it with a drill set to clockwise rotation and moderate speed for best results in thin sheet metal, plastic housings, or softwood.
