See our Time Sert products at DenLors and Time Sert products at Wise Auto Tools.Ĭaller's question - What is the Rescue Bit made of?Īnswer - The Rescue Bit is made of Tungsten Carbide. Helicoil is the most common brand, but we prefer Time Sert because their thread repair system uses sold bushing type inserts rather than a thin coil of wire. Also, remember that the Rescue Bit can withstand a higher temperature than a regular drill bit so cooling is not needed (more on this below).Ĭaller's question - What if I find that the threads are damaged after removing the broken pieces?Īnswer - We sell all types thread repair kits. The desired effect is for the Rescue Bit to cut and not slip, this is another reason not to lubricate. The use of oil will cause the dust to collect and this may cause the bit to bind and break. The reason is because the Rescue Bit makes dust instead of metal shavings. The manufacturer, says do not use WD40 or any other cutting oil like you would normally do with a drill bit. For instance, using in a die grinder will work faster but will dull faster as well.Īnswer - No. Keep in mind that the faster the bit is turned, the faster it will get dull.

Increase speed if needed, until the optimal RPM's is determined. They recommend using slower speeds at first. The maker of the Rescue Bit says that different metals can be drilled best at different speeds. Remember whatever size you use or if it's in a drill or die grinder to use a rounding motion as you go.Ĭaller's question - Can I use a regular drill? What speed?Īnswer - Yes. They never come with the 3/16' collet, so we suggest buying the 3/16' collet if you want the capability of using a 3/16' Rescue Bit in your die grinder. Most die grinders have a 1/4' collet and some come with a 1/8' collet. A die grinder will work faster but dulling may also occur faster as well. So I'd use a drill first so there's more control. The manufacturer recommends starting off slow. Then since all of our Rescue Bits are double ended, it can be flipped over and the other side can be used.Ĭallers Question - Can I use the Rescue Bit in my die grinder?Īnswer - The short answer is yes, I'll explain.

If it does break however, it shouldn't be wedged in tight so hopefully it can be removed without too much difficulty. If this is done properly it is less likely to bind and break. The risk is entirely yours.Īnswer - The way it is supposed to be used, you make a small circular motion when drilling. The manufacturer provides no warranty on the Rescue Bit, just like there's no warranty on drill bits.

Whenever something is really hard, its naturally somewhat susceptible to breaking.Ĭaller's question - Is there a guarantee that it will drill out my broken tools?Īnswer - No. Since it has to be a very hard metal compound, one of the resulting characteristics is that it is brittle. I don't mind spending the money if it really works.Ĭaller's question - Will the Rescue Bit drill the EZ Out and the Cobalt drill bit out?Īnswer - The Rescue Bit was designed specifically for the purpose of drilling out very hard metal compounds, like the EZ Out and Cobalt drill bit material. I drilled the EZ Out with a Cobalt drill bit and it broke also, that's in there too. I had a broken exhaust manifold stud in my engine. Just about everyday we have calls like this Ĭaller says - Let me tell you what I have. He had broken the exhaust stud and then broke an easy out trying to get that out. One customer was quoted $1200 to have one exhaust stud hole cleared of a broken EZ Out, on his boat engine. Some of our customers have received quotes to have a mobile metal disintegration company come out to their location and use an expensive process to remove their broken EZ Out. This makes them very brittle and susceptible to breaking easily when too much force is applied. An EZ Out and other tools like taps and drill bits we already mentioned have very hard metal compounds. The reason is because tools like these were never intended or designed to require removal by drilling. In fact we've had many customers try to drill out broken tools with Cobalt and titanium drill bits, only to spend all day and nothing to show for their time, except several dull or even broken drill bits and a broken EZ-Out still in their engine with just a dimple. 'How do you drill out and remove a broken EZ-Out?' Read below or go directly to our Rescue Bits For Sale section.īroken EZ Outs, various brand spiral extractors, taps and drill bits are virtually impossible to drill out.

We have had many customers call to ask what do you have that can drill out a broken tool like this? Fortunately, we have a tool that answers this question. The metal is so hard that a regular or even a cobalt drill bit cannot touch it.
