5/8 Inch Inside Diameter, 3-1/2 Inch Overall Length, Unidapt, Countersink Adapter MPN:80-L5-278

The Countersink Adapter is ideal for professional machinists, engineers, or mechanics who require a high-precision countersink solution. The 5/8 inch inside diameter provides enough clearance to allow use with multiple drill bit sizes while the 3-1/2-inch overall length ensures sufficient depth to accommodate various counterbore requirements. Made of durable steel, this adapter offers long-lasting performance even when used on tough materials such as stainless steel, aluminum, and cast iron. The unidacent design simplifies installation and prevents damage or misalignment of threads during tightening. Industries that can benefit from using Countersink Adapters include automotive, aviation, and industrial sectors where high-precision hole drilling and tapping are essential components in product assembly or repair work.
