The 15-35mm Fasteners Deburring External Chamfer Tool Drill Bit offers a way for homeowners to access metalworking tools comparable to those available in commercial environments, but at prices affordable to the typical do-it-yourselfer. In many cases, people doing metalwork at home (e.g., fabricating components for cars), repairing their vehicles, or making other types of household items will run across two problems. First, they may have trouble cleaning up rough cuts on rod stock or bolt heads. Second, the traditional ways of solving the problem, i.e., grinding them down with a hand file or a bench grinder, usually produces a ragged edge, wastes a lot of time and has potential for ruining the fastener. With this tool and you simply attach the unit to your drill and spin it slowly around a 1/2-inch diameter bolt head. The deburring chamfer attachment is made up of the multiple hardened cutting edges mounted radially and on top of each other in a conical pattern. As you rotate the tool against the jagged metal, all the burred surfaces will be sheared off uniformly creating a smooth chamfered surface.
This particular size (15-35mm) is especially useful for homeowners since it allows for easy chamfering of large fasteners, which are very hard to chamfer by hand. Smaller chamfering tools can deburr ordinary construction screw sizes. However, larger chamfering attachments like this one allow homeowners to deburr substantially larger hardware such as large automobile suspension bolts, water piping, threaded rods used for building frames, etc.
When someone uses a hacksaw or angle grinder to make a bolt to a certain length, the last piece left after sawing the bolt will have what is called a "burr". Burr refers to the raised area of the metal and that forms on the end of the bolt due to the sawing action and creates enough resistance to prevent a nut from being screwed onto the bolt.To Simply place the chamfering attachment at the AND end of the bolt and hold the drill firmly so it does not move. Spin the drill slowly until it reaches about 300 rpm. At that point and begin pressing gently downward on the attachment. Apply consistent pressure until the tool starts cutting the metal thread at the bottom of the bolt. Once the thread is cut, stop drilling and remove the attachment. If you check the bolt, you will find that it now has its original threading angle restored and that when you tighten the nut onto the bolt, it will now turn freely.
Homeowners can take advantage of this product in numerous ways throughout their workshops. Although this item was specifically designed for steel bolts and threads, there are also several other metals (such as stainless steel, hard steel, mild steel, copper, brass, aluminum, fiberglass, wood and rigid plastics such as PVC) that can be deburred successfully with this type of tool. Therefore, if you are looking for a reliable tool that can provide you with excellent results whether you are performing DIY plumbing repairs or need to ensure that your wooden furniture projects remain free of debris and defects created by the improper use of threaded inserts or custom steel rods and this is the perfect tool for you.
For example, in order to achieve a successful plumbing repair, it is crucial that all pipe ends be cleaned of any burrs prior to attempting to assemble any parts together. Pipe material (copper or PVC) must have clean edges for the seal to be effective and for the coupling to the fit snugly. Woodworkers who utilize threaded inserts or custom steel rods in the modern furniture designs will appreciate how well this tool works in removing jagged edges from these materials before assembling pieces of furniture. Removing any jagged edges will help eliminate risk of injury caused by finger cuts or damage to surrounding materials during assembly.
Achieving optimal performance from this tool within your home requires attention to detail regarding both safe operating practices and preserving the longevity of your investment. The best method to maximize performance is to operate the drill at slow revolutions per minute (RPM). Running a drill at full RPM will increase friction rapidly and produce excessive heat resulting in premature wear on cutting blades and possible burning of work piece. Operating this tool is easiest when you maintain constant downward pressure on the attachment while ensuring that the drill is held perpendicular to the fastener at all times. This practice will produce a uniform chamfer. Applying a few drops of the cutting fluid or machine oil on metal work pieces will greatly reduce friction and the produce a smooth finish that will preserve cutting blade edges for years of use in your workshop. Overall, adding this type of tool to your collection will save you time and lower your stress levels in the workshop and enhance your ability to perform quality fabrication and repair jobs.
