Repeat buyer. I have purchased one size of these taps before. If you have never used fluteless or forming taps before, these are a good inexpensive way to give them a try. I tap into aluminum plate and turn them by adding a one inch diameter knurled handle which can be turned with fingertips if you drill the correct sized hole. These have removed the frustration of breaking taps since you can feel exactly what is happening. I prefer them when packaged in the small plastic cases, but even in the plastic bag they arrived undamaged. Highly recommended.
High quality product. Perfect seller. Fast shipping. Thanks.
