Belleville Disc Spring: 6.2 mm ID, 0.8 mm OAH, 12.5 mm OD MPN:170023

The extra-length drill bit is an essential tool for professional construction or engineering projects requiring deep and precise drilling. Its carbide construction ensures high durability while the Titanium Aluminum Nitride (TiAlN) coating enhances resistance to wear and improves chip flow. Measuring 158 mm in length, this extra-long bit enables easier access to hard-to-reach areas without compromising stability during drilling operations. The presence of coolant through the spiral flutes prevents overheating while cutting and allows for smooth and fast completion of projects. This product is ideal for use with a variety of materials such as steel, stainless steel, cast iron, wood, or plastics and can be employed in various industries like aerospace or automotive engineering where accuracy matters the most.
