The Cleveland 135° Heavy-Duty Jobber Cobalt Screw Machine Drill is made from HSS-CO 8% (M42), which combines the hardness of cobalt with the toughness of high-speed steel, making it perfect for demanding applications. This drill bit features a tool size of 1/4" (0.2500"), with a flute length of 1.3750" (34.92mm) and an overall length of 2.5000" (63.50mm), making it ideal for deep hole drilling and applications requiring higher reach.
The TiCN (Titanium Carbon Nitride) coating on the drill bit enhances wear resistance and extends tool life, especially when used with harder materials like stainless steel and high-strength alloys. The spiral flute design, combined with a right-hand spiral and right-hand cut, ensures optimal chip removal and helps reduce heat buildup, ensuring smooth drilling. The split point with a 135° point angle ensures an accurate start and minimizes wandering during drilling.
The straight shank configuration, with a shank size of 0.2500" (6.35mm) and a shank length of 1.1250" (28.57mm), allows for compatibility with a wide range of drill chucks, providing stability and precision. Designed for heavy-duty use, this screw machine drill is built to handle tough tasks and deliver reliable performance in industrial and high-production environments.
