Q:What drill holes are used in stainless steel basins?

Crazy, what do you want to do?. If the drill or two eyes, ordinary bits, slow speed can. If you drill it into a sieve, choose a high temperature resistant steel bit. To the hardware store to ask, buy a professional drill stainless steel twist drill, it can save effort point.

Q:I want to be in the stainless steel frame and fixed drill a few screws, with what bit and screw

It is the best to drill stainless steel with carbide drills, and if you do not have a carbide drill, you can drill with an ordinary bit;

Q:Why is the drill angle 118 degrees?

Standard angle has 118, 120, 130, 135, 140, processing material is different, drill top angle is not the same.

Q:What causes the drill bit to break at the end of the hole?

When the speed is low, the feed is too large.If the cutting resistance is greater than the twist strength of the drill, the bit can be broken when the speed is low.

Q:What drill is drilled after quenching?

Carbide coated tools can handle around HRC50 of materials, such as Mount Vickers 840, and material 1220

Q:What is the four hole five hole hammer

Four: refers to the pit slot number is four at the handle of hammer drill hole, two key and two ball groove, used in the four pit on the hammer. This drill is usually used in the medium electric hammer.

Q:How do you drill a sharpening bit?

The drill shaft is slanting out of the front angle.." Here is the relation between the axis of the drill bit and the surface of the wheel. "Frontal angle", that is, the vertex angle of 118 degrees + 2O half, about 60 degrees, this position is very important, directly affect the top of the drillAngle size and main cutting edge shape and cross edge angle. To remind students to remember a commonly used 30 degrees, 60 degrees, 90 degrees triangular plate angle of 60 degrees, students easy to master. A formula and formula two refers to the relative position of the grinding beforeThe two should take overall consideration, and don't neglect to set the oblique angle in order to settle the edge of the blade, or ignore the edge of the blade in order to set the oblique axis. These errors are often present in actual operations. At this point the drill is in the correct positionPrepare the contact grinding wheel.

Q:What bit is hard, not easy to wear and punch?

Stainless steel drilling bit, not the problem, of course, is not Never mind, is to buy a bottle of vinegar, vinegar, vinegar is vinegar can be, not tried.

Q:Grinding the drill bit, how can grinding, and the method of quick crash is what ah?

By the back edge grinding behind. This is the slow grinding of the entire flank from the edge of the bit. It is easy to dissipate heat and grind. Based on the stability of the consolidation of one or two of the formula, the drill can be gently contact for a relatively small amount of grinding wheel, grinding, grinding to observe the uniformity of the spark, to adjust the size of the pressure, and bit cooling. When the cooling start again after grinding, to continue to set the formula to the one or two position, it is often in the beginning is not easy to grasp, often can't help to correct change their positions.
