Draper Expert HSS Cobalt Drill Bit

The 9.5mm Draper Expert HSS Cobalt Drill Bit offers versatile drilling capability with its extended 230mm overall length, making it suitable for both standard and deep-hole drilling applications. This popular diameter size is commonly used for mechanical assembly, structural metalwork, and general engineering tasks where reliable performance in tougher materials is essential. The longer length provides the reach needed for drilling through thicker stock whilst maintaining rigidity and accuracy. Manufactured from high-speed steel with 5% cobalt addition, this drill bit excels in applications that would quickly defeat standard HSS bits. The cobalt content enhances both hardness and heat resistance, allowing the bit to maintain its cutting edge when drilling stainless steel, hardened metals, and other challenging materials. This superior wear resistance translates to extended service life and more consistent hole quality throughout the bit's operational lifespan.
