Q:What is the four hole five hole hammer: Actually, what's the difference?:1: four pit is now the longest on the market with better match. Five of the pits will not fit the drill bit.2: the five pit is usually large with a hammer, more than 38, because the big hammer torque, relatively the five pit stress structure more reasonable.

Q:Do you have any special drill for aluminum alloy?: Aluminum alloy, copper, stainless steel, the hardness of these materials are not high, aluminum alloy, copper soft, frequent drilling process, easy to cut, and there will be a lot of burr. The best choice for some Aluminum Alloy drill bits for different materials when drilling drill main cutting edge angle will be different, the best selection of aluminum cutting angle of 120-135 degrees, the feed is not too high, due to the low, if the best friend can understand the material selection of M42, M35 or 6542, not bad bit a few drill does not move. The bit is divided into a rolling bit and a full grinding drill, and the whole grinding drill is 30% more expensive than the rolling mill, but the effect is much better than that of the rolling mill.

Q:What kind of drilling bit is good for stainless steel?: The characteristics of stainless steel is high toughness, easy to stick a knife. So the drill hardness is high, surface finish better than ordinary bits, the bit angle large (130--135 degrees). At the same time to the full amount of feed and cooling. More than 0.15mm as much as possible without cutting in cold hardened layer. The cutting speed is as low as possible to reduce the cutting temperature. The cutting fluid is made of concentrated emulsions. Commonly used stainless steel drills are: high cobalt bit (M35 bit, M42 bit), in which the M42 bit is the most cost-effective, and carbide drills are also available.

Q:What drill can be used to break through high strength stainless steel plates?: Diamond bit, absolutely good, it depends on you do not have to use up

Q:Is it OK to drill holes on tiles with an ordinary bit? Will the tiles crack?: But my home is cheap tiles, give you a weapon:I use the impact hammer drill, not too big eyes when drilling, I only through the 6-8 (i.e. 6-8mm diameter) of the eye;

Q:What chisel drills are used for building water utilities?: Now is the use of play slot machine, before impact drill plus pointed and flat chisel and hammer.1, can use the slotted line pipe cutting machine, can also use the shovel,2, the most simple and practical way to slot the box is to use diamond in the groove where the direct drilling,3. The diameter of the hole is determined by the size of the wire box. For example, 86 of the wire boxes can use 100 of the drill bits.4. The depth of the wire box is the depth of the borehole.5, knocking out a hole in the middle of bricks and then trimming.6, such open line box groove position standards, size appropriate, also easy to use mortar filling fixed.

Q:What drill is drilled after quenching?: Quenching: a heat treatment process for quenching of metals and glass. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above the temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms ISOTHERMAL MARTENSITE () or bainite) heat treatment process transformation. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process.

Q:My drill iron chuck is missing. How else can I take the drill bit off?: The drill bit comprises a cutter rod, a cutter rod, a tip, tip two is located in a main plane (C - C) on the cutting insert (5, 5 '), the cutting blades (5, 5') have in common second planes (E - E) on orientation short cutting edge center. The blade forms a point like center, the cutting edge is used to enter the workpiece, and thereby the bit is aligned. Two chip grooves (6, 6 ') are arranged on the cutter bar, and the chip removing slots (6, 6') extend from the tip to the end.

Q:M3 threaded hole. The bottom should choose large diameter drill bit: What do you not know about screw diameter reduction? M3 the pitch is 0.5, that is, 3-0.5=2.5.. If it is a piece, it can be larger. Choose 2.55 to 2.6 of the drill bit. All other materials are 2.5.

Q:How big is the drill bit for the 7mm hole?: If the big point is OK, use 6.5 bit to drill a hole, and then use 7 bit reaming, we can get 7.0-7.1 hole, directly use 7 bit drilling, the hole error is the biggest. Hope to be helpful to you, please adopt.
