Bearing on the single cone bit, teeth, cone dorsal and disposal flow was enhanced and improved, according to the cbn grinding wheels construction of various problems. Improved single cone bit in the application of slim hole drilling was a great victory, overcoming the previous single cone bit various defects, eliminating the single cone bit teeth easily fall dorsal easily pierced, too more from the drilling and drilling higher interest rates and other issues, field application is effective and can improve the sidetrack drilling speed, shorten the drilling cycle, thereby reducing drilling interest, can be applied by oblique drilling, more suitable for steady oblique drilling, more suitable for slim hole drilling.
Now commonly used in small-size drill mainly tricone bit, PDC drill bits and single cone bit, PDC drill bit due to the sds plus drill bits structure and working principle of limitation. Among them, three cone bit bearing most obvious disadvantage is small in size, mainly by the impact, crush and squeeze a small way from scraping rock breaking, drill teeth touch bottom number changes, dental discontinuity, short bearing life .
Not only work when torque is large, the cutting tools teeth washing and cooling difficulties, and its strong sensitivity of lithology, stratigraphy and is not suitable for drilling hard and soft gravel staggered formation; single cone bit more applicable than three cone drill in both strength and ductility are large formations, while for PDC bit difficult to deal with hard interlayer and other complex formation, and the structure is simple, bearing a large space, the use of safe, reliable, easy to drill size miniaturization field use to good effect.

alloy blades
(2) The equipment shall be equipped with safety devices, such as: protective cover, power brakes, overload protection.
3 There are professional operators to sds drill bits install and use, and wear work clothes, wearing goggles, earmuffs and so on.
4 operator can not wear gloves, long hair work to be placed inside the cap, and pay attention to ties and cuff, to avoid any danger.
5 away from the fire source and humid environments.
Installation Requirements
1, the equipment in good condition, spindle no distortion, no track jump, fixed solid, no vibration.
2, check the blade for damage, tooth is complete, sawn board is flat and smooth, and the presence of other anomalies, in order to ensure safe use.
3, the assembly, make sure the blade spindle rotation direction of the arrow with the device in the same direction.
4, the blade installed to keep the axis of the circular saw chuck and clean flange, flange diameter of the blade diameter, ensuring that the blade flange closely integrated, installed dowel pins, tighten the nut. Flange size should be appropriate, outside diameter shall be not less than the blade diameter of 1/3.
5, the device before starting, to ensure safety in the case, a single person to operate the equipment, jog idling, check the device rotation is correct, with or without vibration, blade installed idling after the first few minutes, without slipping, swing or normal after beating work.
Requirements
1, work, work should ensure that fixed profile positioning in line to eat cutting direction to avoid abnormal cut, do not exert side pressure or curve cutting, feed to a smooth, avoid contact with the stone drill bits workpiece edge impact resistance, resulting in damage to the blade, or workpiece flying out of an accident.
2, the work, and found abnormal sound and vibration, cutting surface roughness, or odor, you must immediately terminate the job, timely inspection, troubleshooting to avoid accidents.
3, at the beginning and stop cutting cutting, do not feed too fast to avoid broken teeth and damaged.
4, if the cutting aluminum or other metal, to use special cooling and lubrication fluid, to prevent overheating of the blade, resulting in tooth paste, and other damage, affecting the cutting quality.
5, flutes and suction equipment to ensure smooth flow of slag device to prevent slag accumulation into blocks, affecting production and safety.
6, dry cutting, do not long continuous cutting, so as not to affect the life of the blade and the cutting effect; wet sheet cutting, water jet cutting should be added, to guard against leakage.
