For blind holes, choose a spiral flute tap like this OSG M22x2.5 model, which pushes chips out of the hole. Ensure the chamfer type matches your thread depth requirement—modified bottoming chamfer allows threading closer to the hole bottom. Match the tap tolerance (D8 / 4H-6H) to your desired thread fit class.
