Nov 10, 2004 I use nitric acid frequently to remove broken taps & drills from stainless steels & titanium. Use 1/3 distilled water and 2/3 nitric acid. I build a dam around the tap with modeling clay and use an eyedropper to fill the pocket with acid. High alloy taps will take much longer than M2 HSS taps to dissolve. When you add the acid, the reaction ...

Feb 01, 2018 The RPM's were 3600 and the knee was used to advance (very slooooowly) to the depth of the carbide ball mill. A water based lubricant was also used to keep the heat from building up.

With the receiver still in the vise you can mill the two

To cut the final shape of the receiver you are going to remove a lot of metal. I suggest you use only USA made cobalt, or carbide ball end mills. I use a very good 3/8 inch carbide Ball end mill. I only make conventional cuts and keep the leaf screws tight, any slop in your set up, means a broken end mill.

May 24, 2013 Just find some carbide thing that fits in the hole. Zing the RPM's up and feed lightly, try to blow the chips out and when you feel a crunch get the broken carbide chunks out so you can keep going. Just yesterday I made a fixture from scrap 6061 plate to bolt to a cylinder head in-situ to run a 5/16 carbide endmill held in a cordless drill to cut the center out of a snapped off 10mm manifold bolt.

Jul 25, 2019 Pick the correct extractor size. Insert the fingers in the flutes as deep as possible. Slide the collar down against the tap. Use a tap wrench to turn it until the tap comes out. This method is fairly quick, but may not be very effective as the extractor fingers tend to twist off if the tap is too deep into the hole.
