To modify the toggle bolt, all you'll need to do is remove the shoulders of the anchor. I've included images in this step to show what I mean by 'shoulders' as well as before and after images. Once you've taken a file or a grinder and removed the 'shoulders', it will make the profile of the anchor more flat, which is also good because it'll catch better on the bottom of your drill press. As the name states, it is a “safety” device. It’s an extra effort to prevent a single joint or a complete string of pipe from dropping down the hole.

Now, it's fair to mention that the ones I bought fit very neatly on a 3/8" carriage bolt (it's 1" in diameter). If you plan on using a 5/16" or 1/4" carriage bolt to match the nut you implanted into the toggle clamp, you might have to do a little more searching for a rubber solution. You might try a rubber tool dip if you aren't able to find a small enough rubber furniture tip, or even scrap the carriage bolt completely and go with a threaded rod of the same size with a pre-drilled hole in a rubber stopper. But why does flat matter? Flat matters as clamps require two surfaces for clamping, both of which should, in theory, be parallel to each other. Using claps on my drill press was a balancing act...one that I never seemed to win. Do not use a safety clamp in combination with automated slips. This does not create a safety factor but becomes a hazard. When using automated slips, and you install a manual safety clamp, you will risk major equipment damage should you encounter an impact. Even though Company Rep’s might insist in using the clamp in this configuration, it is strongly recommended not to do this. So what we'll do is use a little paint and paint wide enough strips under our drill press table, on the ridges, that will be long enough to place our toggle anchors onto. We'll press the anchor onto the ridges and make sure that the bolt is in the center. Once the paint has been transferred, we'll want to remove about an 1/8" of metal so that the ridges on the underside of the drill will fit in the anchor. Again, you can do that with either a file or a grinder.Once we've found a rubber solution to the business end of our bolt/threaded rod, we'll head on over to the next step. Once the shoulders are removed, we'll do something that will keep the toggle anchor from skidding off the ridges of your drill press table: we'll make notches exactly where the ridges are. Now, we could measure these things out...but I like working with patterns and allowing objects I'm working with to print themselves, giving me a more exact, less mistakable procedure. So what do I do? Understanding the operation of the slips will make you understand the purpose of the safety clamp. Why do we use it in our daily operations on the drill floor, whether we run Drill Pipe, Casing or Tubing? Do not ever use a safety clamp as a hoisting device. This device was not build for lifting and is not rated as such. The handles on the clamp are for manual handling, not to be used as pad eyes.

The other extremely common one is what I call in “insurance” model of risk assessment. In insurance the loss of life has a very low value because dead people don’t sue. In reality average people have a much higher regard for life. An ideal drill guide for all the rotary tools in the market today. The easy to use guide has a lever to adjust height and is heavily preferred in the manufacturing industry. This jig really is a two parter, depending on what you're planning on doing. If you already have some sort of jig you've rigged up for your drill press, Part 1 is all you need. You will, of course, need to create a channel in your jig so that you can slide your jig below the Part 1 clamp. The tool is perfectly suited to Dremel rotary tool models 400, 398, 395, 300, 285, and 275. Since Dremel is such a popular brand, consumers will want specific accessories that work perfectly with their Dremel power tools.

No banging on the clamps, please!

Usually the safety clamp is used until sufficient weight is reached in the string. This will vary according to tubular specs. Small drill guide that is ideal for medium sized workshops. The stand weighs 2.5 ounces and is comparatively quite light, the guide can be used for precise holes and is perfect for wood crafters. The safety clamps basically come in three different types, and are manufactured by various companies around the globe. The most common name on the drill floor is “Dog Collar”.
