Drill Bits
1.Tighten the bits when screw on. 2.When the bit lower down to the bottom , Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling. 3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay. 4.When drill jammed, withdraw first, should not to force the rig start. 5.Drill could not without water, to ensure that the bit will be too hot. 6.Use the bits in right order , big size first, then small one . 30*35*40cm 45kg
The used tricone bits are much more cheaper than the new ones because of the cost is low, but the quality is promised. 30*35*40cm 45kg
PDC Drill Bits are equipped with Hardened Alloy Steel base material;High performance PDC-Cutters;Carbide and Diamond gauge protection;Carbide/Diamond Shock Studs;Threaded or Plain Carbide Nozzles for Flushing
LAKE offers crown impregnated height segments of 9mm, 12mm, 15mm, 16mm, 18mm, 20mm, and 25mm Diamond Core Drill Bits. Roschen also can supply different kinds of diamond core bits in different size, which are used in shale, sandstone, limestone, marble, dolomite, schist, granite, quartz, ironstone, chert, abrasive rock etc. Which including impregnated diamond core bit, surface-set diamond bit, reaming shells, casing bit, casing shoe bit, core lifter, core lifter case, core barrel assembly, inner tube head assembly, over shot, hoist plugs, drill rod, casing pipe etc. Advantages: Surface-Set diamond bits are primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. They are also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations. Notice: To select the right bit: 1) Please assess the speed and power of your drill for the size and depths of the holes 2) Please assess ground conditions (such as Stone / Granite / Concrete ) and down-hole conditions. Size: 1) LAKE have all standard size of Diamond Core Drill Bits (Surface-Set) . 3) Different customers have different requests, we can make customize Diamond Core Drill Bits. Crown Height: LAKE offers crown impregnated depths of 9mm, 12mm, and 16mm Diamond Core Drill Bits. The taller crown heights can improve bit life time, have better stability and performance, reduce vibrations. Specially about Waterways: Diamond impregnated bits are suit for various waterways. Diamond Core Drill Bits suit better flushing in various ground conditions and drilling systems. Threads: 1) Standard WL threads 2) As well as thread types required by clients are available.
