CK T310004TD Drill Bit HSS 4mm (Pack 2)

The CK T310004TD is a professional-grade HSS (High Speed Steel) metal drill bit designed for precise, efficient drilling in a wide range of metals including steel, cast iron, and non-ferrous materials. Engineered for trade and workshop use, it delivers clean cutting performance, durability, and accuracy in everyday drilling applications.

Manufactured from high-quality high-speed steel and precision ground for consistency, the T310004TD features a 135° split point tip that helps eliminate drill wander and ensures accurate starting without the need for centre punching. This improves control and reduces setup time on site or in the workshop.

The optimised flute geometry enhances swarf removal, helping to reduce heat build-up and maintain smooth, efficient drilling performance. Its compact jobber-length design makes it ideal for general-purpose metalworking where precision and control are essential.
