Drilling (or sawing) of neodymium magnets is absolutely not recommended. First of all, the material is brittle and fragile. Secondly, drilling causes combustible dust and, thirdly, the heat caused by the drill can possibly demagnetise the material. Specialists can work with the magnets with specialised diamond-tipped tools and constant water cooling. However, this normally occurs prior to magnetisation of the material.

Smallest achievable hole size (and largest achievable hole size) is dependent on the material, material thickness and laser used. It is possible to drill 1 micron holes through thin material at aspect ratios of up to 100 to 1. It must be remembered, however, that there will usually be taper associated with the holes and the entrance diameter will be larger than the exit. We normally specify EXIT diameters.

Zinc provides sacrificial protection to steel with steel beginning to corrode once there is no zinc present. Applying a zinc-rich paint over a drilled or exposed area will provide corrosion protection. See similar questions...

Use a carbide-tipped masonry bit or diamond drill bit; Fegular twist-drill bits can't cut through the fire-hardened glaze. Not necessarily. Porcelain tile is no different in temperature than anything else in the room except that it holds its temperature better because of its mass. Of course, cool is good in warm weather climates and it's easy to warm things up with an area rug or two. See similar questions...

We recommend the hole be a factory supplied option. What we do is actually disassemble the valve, indicate the ball dead center on 1 side, drill deburr, reassemble and then test the valve. This way we are certain that if the valve is installed following the manufacturers instructions, there will be no problems. See similar questions...

We recommend securing the model on a survey table. Then prepare the drill hole in the model using a drill press (available from any hardware store). Freehanded drilling is not recommended. See similar questions...

The wood at the center of the piece has almost a  “Zero” velocity across the tip of the tool, and that can make it difficult to turn. Sometimes this is a problem, and sometimes it isn’t. Sometimes I drill into the center, and sometimes I don’t. Sometimes I don’t, then change my mind, and drill later.  Sometimes I do when I didn’t need to, and then it was a wasted effort.  I don’t think it matters. See similar questions...

No. The system can be installed differently depending on your needs. We recommend drilling a hole to allow the camera to be mounted on an angle, which gives you depth perception and a wider viewing area. See similar questions...

No. Although some offices use this technique to acquire better adaptation, we at ChicSmiles do not recommend drilling a hole. With no hole drilled, you can easily remove this crystal without further procedures to cover the hole. See similar questions...

Open the hood and look at the firewall, all the way towards the driver side fender, below the driver's windshield wiper. You will see a large black 2" x 3" wiring harness that passes through the firewall which is secured by a nut along the top edge. You can drill a hole just off the lower left corner of this connector from the inside of the car. See similar questions...

Porcelain is very hard and has to be cut using a diamond drill under running water to keep the sample cool. Any excessive heating would interfere with the TL. A hollow core drill is the safest way of doing this. The core is cut into thin slices using a fine, water-cooled diamond blade and the slices used for TL (pre-dose) measurements.

quot;On-Glass" antennas are easy to install and do not diminish a vehicle's value by drilling a hole. Care must be taken during installation to ensure that the antenna is mounted high up on the glass and not over defogger wires or on reflective window tint and this could impede performance. quot;Rear-Dash" is also another option, however performance losses will occur.

Yes, excellent traction BOTH wet & dry. In fact, better than wood. This is due to a combination of product formulation and our embossed grain surface. See similar questions...

For the first time EZ Stent user, we recommend passing your pilot drill through the drill sleeve once prior to surgery to ensure no obstruction. The pilot drill sizes of different brands may vary slightly (Ø2.0mm to 2.3mm). Tip: A pilot drill from Straumann (Ø2.2mm short or long) fits particularly well in the EZ Stent, and can be used to substitute the pilot drill of any other brand. See similar questions...

Slate can be drilled with a normal electric drill or better yet is to use a drill press. The drill press will drill the hole straight without it going from side to side. Use a masonry drill bit. This bit is used to drill stone, brick and motar. Always use a new sharp bit and plenty of water to keep your drill bit cool. Keep your slate wet all times, this makes it easier to drill and remember to clamp your slate down to the table or drilling plate. See similar questions...

We do not recommend spraying foam into areas that you cannot actually see. Foam expands in every direction. FOAM DOES NOT EXPAND IN THE PATH OF LEAST RESISTANCE. Expanding foam may bow, buckle or burst the area. If high-pressure expansion is a concern, you may be interested in our No-Warp Low-Pressure Window & Door Gun Foam, or our Quick-Cure Reduced Expansion Cylinders. See similar questions...

You will have to drill a hole, and the diameter is critical, we can advise with orders if requested. For a clean hole in plastic we advise the use of an electric drill with metal cutting drill bit. Information sheets provided give details of the procedure. See similar questions...

ANSWER: Don't be afraid of this mod. It's really pretty simple and I'm pretty sure I could have done it w/ a 3/8 drill, a good 1/2 x6" bolt and a hammer (but the drill press and arbor press made it a piece of cake). See similar questions...

Do not drill holes into the cabinet to install a padlock. The condenser coils welded inside the cabinet will likely be punctured. The refrigerant gas will then leak out and the unit will require major repairs. Frequently clean the door gaskets and the mating refrigerator surface. Any sticky buildup will put added stress on the gasket material and lead to premature failure. Apply a thin layer of Vaseline or use some silicone spray on seals when clean every 12 months.

If a check valve is being used we recommend drilling a vent hole. This hole is located in the basin between the pump and check valve usually a few inches above the pump "on" level but below the pit cover. The vent hole will prevent air locking from occurring (pumps runs but will not remove fluid from tank or basin). See similar questions...
