Belleville Disc Spring: 8.13 mm ID, 2.18 mm OAH MPN:BC0896020S

The screw machine length drill bit is designed to provide precision machining capabilities for professionals involved in engineering and manufacturing. Made of high carbon steel with a standard 1/4'' shank diameter, it boasts superior hardness and wear-resistance while ensuring consistent cutting performance across varied surfaces. With its straight flutes for faster chip removal, it excels at drilling intricate holes accurately to produce high-quality machined parts with precise tolerances required in the medical, aerospace or automotive industry. The 7/32'' diameter makes it suitable for cutting through softer materials like aluminum and brass with minimal pressure while its 130 degree point angle allows you to adjust drilling angles based on your specific needs. Its ability to produce quality results repeatedly with reduced risk of damaging surrounding components makes this drill bit a valuable tool among engineers or machinists who demand consistency and precision.
