Sealey SMS01 Drill Bit Sharpener Grinding Attachment

Product Information

An alignment system this secure means that you will have no problems maintaining accurate bit geometry without damaging your tools' integrity of your tools. An eccentric was added and calibrated to allow setting the primary relief angle easily by tilting the trunnion table. The 4 facet sharpener works well for drills from 1/2" down to about 0.060=#53; smaller drills can be sharpened with 2 facets ( see below). On the left is an 0.080 test pin ground to evaluate alignment of the wheel to the trunnion table axis; here the primary facets (silver) don't meet properly in the center - the wheel needs to be a couple thou farther from the table to correct this. D" bits can be sharpened or even produced in the fixture. Generally, it takes a while to remove much metal by hand with a stone so where possible rough the shape on a bench sander or grinder first then finish to the desired angles in the HoneDrill.

I now use the powered 4/6 facet sharpener described above for most drills although I continue to use the hand powered sharpener for drills under 1/16". SPA's are added to drills larger than 1/8" using the motorized 4 facet sharpener so the HoneDrill isn't used much any more. You’ll find that the best drill sharpener will use a diamond wheel. These wheels are heavy-duty and can easily handle tough carbide bits. Alternatively, if you use a lot of carbide bits, you can look for a bench grinder attachment. This means that you can make sure that your grinder uses a diamond wheel. The Stability of the SharpenerMy understanding of drill point geometry and drill sharpening improved considerably from reading Mazoff's article and especially from using the HoneDrill fixture. Adjusting and using this fixture is effectively a mini-tutorial on drills and their geometry. Plus, it allows experimenting with relief angles, easily allowing four facet and six facet sharpening of drills, for example. Derek Brown's sharpener is much easier to build and use but doesn't illustrate drill geometry variables as well since they are fixed during construction. Hand powered drill sharpening is practical for very small drills but for drills greater than 1/16" I eventually designed and built a powered 4 facet sharpener (to implement some of Mazoff's notions) which I prefer to all other powered sharpeners I've tried.

On the less bright side, the model is a tad too loud for our taste. It's not necessarily deafening. You won't need earbuds. But the engine is a little too loud considering that it is not that powerful in the first place. The relatively low maximum RPM means it will take some time to sharpen larger drill bits. Another thing to consider is whether the sharpener has an adjustable angle. A good sharpener will let you adjust the sharpening angle to suit each individual drill bit. Drill point angles can vary from 118 to 135 degrees.With some machines, like those made by Drill Doctor, you turn the drill bit over and repeat the process. Keep in mind that some drill bit sharpeners work as an attachment to your bench grinder. You can still use your grinder, but the attachment takes the guesswork out of getting the right angle. What Should You Look For When Choosing a Sharpener? Another thing to consider is the cost of the drill sharpener and whether you’re going to get the best value for money. To determine whether buying a benchtop sharpener will be worth it, you should ask yourself how often you’ll be using it. If you’re constantly sharpening your bits, then this could definitely be a good investment. It will save you money because you won’t have to replace your dull or broken bits constantly. These specialized sharpeners are the easiest to use; once set up, they need minimal adjusting before they are ready to go. Their specialized function and ease of use make them a good option for beginners and professionals alike. If you don’t need the versatility to sharpen other tools, this is a good way to go. Most bits use either a 118-degree angle or a 135-degree angle. You will find that there are drill bits that might use a different angle, but these two are the most common ones. Is it possible to sharpen Titanium bits? Different drill sharpeners use different types of grinding wheels. The best one for you should reflect what your bits are generally made from, as not all grinding wheels are suitable for all bit types. The Type of Drill Bits

The model's pretty versatile too. You'll be able to work with HSS titanium, cobalt, and carbon steel bits. In fact, you'll be able to work with just about any drill bit ranging from 3 to 13 millimetres (3/32 to 1/2 inches). Allied UK Delta_HTR is the most versatile machine on the list. Just like every other sharpener here, the model is able to work with any drill bit ranging from 3 to 13 millimetres (3/32 to 1/2 inches). At the same time, this machine will sharpen straight-edged knives scissors, plane irons, and many other blades between 6 and 51 millimetres.

Plus, there are slots on the bottom that you can use to mount the machine to just about any workbench. This way, you'll be able to reduce vibrations and make this sharpener much more practical since you won't have to support its frame with your second hand.

Drill Bit Sharpener Plans

Infeed moves the drill along its axis relative to the trunnion line to allow grinding more material from the drill (on planes parallel to the previously ground facets). Development Make sure that you store your sharpener in a dry environment. This will stop the tool from becoming rusty or corroded. You might also notice chips or dents on your bits that need to be smoothed out. A bench grinder is often best for this purpose but it can be done on a Drill Doctor DD500X; it will just take a little longer. The sharpener will have no issues re-grinding chisels and plane blades up to 50-millimetre wide. You can adjust its bevel between 15 and 50 degrees, meaning you should be able to work with/access just about any sharp tool in your toolbox.
