	Drill bit sizes - Wikipedia, the free encyclopedia
		Drill bits of the less routinely used sizes, such as 2.55 mm, would have to be ordered from a specialist drill bit supplier.
		This is appropriate, because the tolerance of the diameter of drilled holes is closer for smaller drill bits.
		Center drills are available with two different included angles; 60 degrees is the standard for drilling centre holes (for example for subsequent centre support in the lathe), but 90 degrees is also common and used when locating holes prior to drilling with twist drills.

	Knowing your drill bits (Site not responding. Last check: 2007-10-15)
		To drill a satisfactory hole in any material, the correct type of drill bit must be used; it must be used correctly and be sharpened as appropriate.
		Good quality drill bits can be expensive, so take care of them, keep them in a case or box if possible, rather than allowing them to roll around loose in a toolbox where the cutting edges may be damaged.
		These bits are used to drill fairly large holes and they give a flat bottomed hole (with a central point) so are ideal where the head of a screw/bolt needs to be recessed into the timber - always use this bit before drilling the clearance hole for the bolt.

		Selecting the proper drill bit is critical for an exact fit between the copper tubes and the wood.
		When we choose a drill bit to use with a kit we test all drill bit that are slightly over the actual OD of the pen kit tube.

	Continuous Drill Bit Sizes - English Measurement

		Where the number 1 drill bit leaves off the letter A (smallest) begins and continues through the letter Z (largest).

		One of the more annoying things about living in a non-metric country is that small drill bits are not given sizes in any human dimension.
		Instead, size numbers are used instead (here, as with wire "gauges," bigger numbers equate to smaller bits).
		Following is a table giving drill bit size conversions for those bits most likely of interest to BEAMers (namely, bit sizes of use for building PCBs).

	GeoGem - Oilfield PDC Drill Bits
		The PDC cutters are mounted on the bit face and gauge area which assists in reducing gauge wear in abrazive formations.
		These drill bits are used in soft to medium formations typically shales, sands, soft limestones and some dolomites with medium to low compressive strengths.
		PDC bits produce large volume of cuttings due to the speed of penetration and operators should ensure that flush volumes are adjusted to keep the bit face clean and cool.

		My reasoning is that I've got a garage full of litterally hundreds of drill bits and several friends and family members with the same situation as me, I was sure that I could find the correct size drill bit.
		After comparing a couple of bits, it seemed like 9/32" drill bit fits the best but it didn't fit exactly right, the first hole I drilled with it, the start of the thread was wierd.
		There are fractional drill bits 1/4 3/8 1/2, there are letter drill bits that follow wire sizes 1-80, and there are letter drill bits A-Z and then there are Metric drill bits.

		For metalwork, this is countered by drilling a pilot hole with a centre drill.
		However, due to its high cost and brittleness, it is more frequently used only used in smaller pieces screwed or brazed onto the tip of the bit.

	Hex based drill bits
		If drill sets with hex bases are not available perhaps a hex base could be bought separately into which the standard bit could be inserted and permanantly fastened by solder or some sort of epoxy glue.
		I have had drill bits snap many times and the resulting failure has never resulted in shrapnel - merely a broken drill end which had to be removed with a pair of pliers.
		Drill bits with hex bases are commonly available as are the quick change type chucks to which the author refers.

	Diamond Drill Bits
		Core drill bits have a hollow center and cut a circle in the material to create a hole.
		This results in a hole the size of the drill and a smaller "plug" or "core" which comes from the center.
		However, since Blunt Nose bits drill out the complete hole, they also drill more slowly than the Core bits and they are generally not used on the super hard abrasive materials such as ceramic or porcelain tile, floor tile, limestone, slate, marble, granite or other stones.

	Technical Tip Working With Sheet Metal
		The drill stop is a little spring thing that fits to the drill bit, and stops the bit shooting through the hole when it breaks through, preventing you drilling your or somebody else’s finger, the underlying structure etc., etc. The other is the 90-degree cup jig.
		You fit various collars into this hole depending on the size of drill bit you are using, and once the cup is seated on the work, you drill down through the cup at exactly 90 degrees.
		A reamer cuts metal in a different manner to a drill bit (you don’t need to remember that) and is more precise, does not snatch the work and produces a cleaner hole (you do need to remember that).
