22 Button Bit Face Designs Button Bit Face Designs 19 Standard button bit Soft rock button bit Heavy duty button bit Retrac skirt button bit General purpose button bit, for use in medium to hard rock ( Rock hardness MPa). It normally has these characteristics: Flat face, parabolic or hemispherical button. For use in soft rock ( Rock hardness < 150MPa). Compared with standard button bit,it normally has these characteristics: smaller button, bigger flushing hole and groove, better wear resistance, drop center, parabolic or ballistic button. For use in extremely hard and abrasive rock ( Rock hardness > 250MPa). Compared with standard button bit, it normally has these characteristics: more buttons, bigger button, better impact resistance and wear resistance, spherical or hemispherical button. Because of more buttons, its cost is higher than that of standard button bit. The Retrac skirt button bit has cutting edges at the rear of the bit, which facilitates the bit removal from the hole. This is an important feature when drilling in loose, broken or fissured rock, where it can be difficult to retract the drill string due to hole collapse. In addition, the Retrac skirt button bit has deep grooves milled along the bit body for efficient cutting removal. The good guidance of this bit gives straighter holes.1-3 designs of bit are available in a retrac skirt. 69 Creek Street, Drury, Auckland, New Zealand

23 Button Bit Insert Types Parabolic Hemispherical Semi-ballistic shaped, more aggressive than the spherical carbides, for use in soft to medium consistent rock. Hemispherical shaped, more aggressive than the spherical button, for use in medium to hard rock, with fractured or seamy applications Button & Body 20 NOTE: Generally, the larger the number of gauge buttons the better overall performance, especially in hard rock.

52 Quality Warranty Warranty Conditions and Procedures of Claim Settlement (Threaded Button Bit) In order to make customers familiar with our warranty and claim settlement, we indicate the conditions and procedures in details as below. 1. Full compensation for the following two situations: a. Steel body breakage when lifespan of the bit used is less than 1/3 of its normal in comparison to the average lifetime of JSI bits delivered to the same client under the same working condition. b. Carbide button breakage or popping-out when the wearing of the button is less than 1/7 of its original height out of the steel body. 2. Partial compensation for the following conditions: Steel body breakage or Carbide button breakage or popping out when lifespan of the bit used is between 1/3 and 1/2 of its normal in comparison to the average lifetime of JSI bits delivered to the same client under the same working condition, JSI will provide partial compensation. 3. In principle, compensation will not be made for pure fracturing of carbide button as the reasons resulting to fracturing are complicated (such as improper operation, drilling concrete with steel wire rods). 4. Generally compensation will not be made for breaking & cracking of steel body and breaking & dropping-out of carbides under the condition that they have been over worn-out. 5. Reasonable compensation shall be made in accordance with the degree of wearing of the threads and buttons, if the bit body or carbide is broken, fractured or drops out under the condition of being used in weathered rock, limestone or other soft rocks. 6. Should the same problem occur for initial bits out of any bulk order when customer starts using the bits (i.e. first five pieces of bits prematurely damaged in the same way), please contact us or your suppliers immediately and stop using the remaining products, we will provide timely service and settlement (such as replacing the bits). Otherwise, we will not bear the responsibility. 7. Procedure: should the above-mentioned situations take place, please send the damaged bits in time to our technical department. Our reply shall be given in one week in compliance with our service commitment and handling standard. Distributor or Agent must offer written quality problem report issued by end-user for return shipment of goods In case other disputes happen, please send the remains of the drill bits to our company, and we both parties shall solve the issue by friendly negotiation. 9. Limitation on Liability.

The liability limitations shall apply even if JSI has been notified of the possibility or likelihood of such damages occurring and regardless of the form of action, whether in contract, negligence, strict liability, tort, products liability or otherwise. The parties agree that these limits of liability shall survive and continue in full force and effect despite any termination or expiration of any Contract. Any action by Purchaser against JSI must be commenced within one year after the cause of action has accrued.

If the related piston is chipped too and the order of failure between shank adaptor and piston can not be measured, we do not offer compensation. 4.
