Q:Why not hammer drill iron: The characteristics of the electric hammer drill:1, a good shock absorber system: allows the operator to hold comfort, relieve fatigue.The way to realize is realized by vibration control system;Through the soft handle increased comfort grip;2 、 accurate speed control switch: when the touch switch is lower, it can help the machine to drill smoothly (for example, drilling on the smooth surface of tile, not only prevents the drill from slipping, but also prevents the hole from breaking. High speed can be used during normal work to ensure efficiency.3, stable and reliable safety clutch: also known as the torque limiting clutch, avoid large torque during use due to seizure caused by the reaction of bit transfer to the user, this is a kind of safety protection of users. This feature also prevents the gears and motors from stopping rotating.

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 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:Which material, gb1436 and 6542, has a good drill?: 6542 is a high speed tool steel.Most of the drilling holes for high-speed processing, so the majority of small drill bit is 6542, this is the must choose.Most drilling holes are low speed processing, and the manufacturing cost is considered, so most of them do not use 6542.GB1436 "straight shank twist drill", this is a standard, is a straight shank twist drill specifications, size, not material.

Q:What drills are used in stainless steel drilling?: We can also use stainless steel chip breaker, S carbide drill, four bit drill bit and indexable carbide drill.

Q:What is the geometric angle of the drill bit?: The commonly used bit, roughly divided into rolling twist drill, full grinding drill, is divided into straight shank drills, taper shank drill and 1/2 drill, double auger, single head, short drill center drill, six angle shank drill, electric hammer drill, impact drill, the material can be divided into 4241# and 4341#. 9341#, M35, M42, 6542#, and alloy etc..

Q:Impact drill and electric hammer drill is what is the difference: Impact drill and electric hammer drill bit is different: the impact drill used, need to tighten the special key. Is the electric hammer drill for electric hammer, electric hammer drill with locking clip assembly, simple, without any tools.

Q:Drill bit specifications: No, because the diamond drill bit and drill, impact drill bit ordinary regardless of specifications, size and shape are inconsistent, on the one hand can not install the clamping key is no guarantee of safety and accuracy.

Q:Do we need drill bit for cast steel drilling?: In the drilling of concrete materials and stone materials, the use of percussion drill, with masonry drill, cutter material is generally hard alloy. Ordinary household, do not drill holes in cement wall, use ordinary 10mm specification flashlight drill.

Q:How long the hand-held electric hammer drill: Hammer is portable!Electric hammer drill know there are 1.2 meters, the longest not seen don't know
