Deluxe Bottle Stopper Tapping Kit - Stainless Steel - Made in USA - 3/8 x 16 tpi

    * 3/8″ Bottoming Tap* 3/8″ Spiral Tap* 5/16″ Stub Drill Bit* 11/32″ Stub Drill Bit* T-Handle Wrench for Tap This complete tapping kit is great for any of your projects that call for a 3/8″ x 16 tpi threading.   The 5/16″ stub bit works best as that is the correct size to use for tapping a 3/8″ hole in common wood species.  The 11/32″ stub bit is used in resin or acrylic or wood that is very hard to tap.  With a little larger hole, the tap doesn’t need to cut in as deep to create threads.   The stub bits work best as they eliminate wander if it hits a tight grain in the wood; the longer wood bits will get knocked off center and you will be drilling a crooked hole.  The T-handle just makes taping so much more simple.
