Universal Engineering Works manufacture non core diamond bits. These bits are also known as Bull Nose Bit.
As the name suggest these non core bits are manufactured for Non Core Drilling where core is not required.
Thin wall diamond core bits are designed for drilling through reinforced or plain concrete, masonary drilling, marble, granite, concrete drilling and other hard materials to fulfill the needs of engineers, builders etc. These bits are ideally suited for extraction of test cores in concrete, highways, runways, concrete columns, reinforced concrete walls and floors etc . Test core of various diameters can be obtained using UEW thin wall diamond core bits.
Thin wall diamond core bits or concrete core drilling bits are designed for drilling through reinforced concrete, masonary drilling, bitumen, marble, granite, concrete and other hard materials to fulfill the needs of engineers, builders etc. These bits are ideally suited for extraction of test cores in concrete, highways, runways, concrete columns, reinforced concrete walls and floors etc .
Test core of various diameters can be obtained using Universal Engineering Works thin wall diamond core bits.
Both surface set diamond core bits and impregnated diamond core bits are available. Both surface set diamond core bits and impregnated diamond core bits are available.
These thin wall core bits are also know as masonary diamond core bits. The narrow kerf of these bits gives a fast rate of penetration.
Sufficient coolant must be circulated to remove cuttings and keep diamonds cool while drilling. Thin wall diamond concrete drilling bits can also be supplied with extension core barrels to suit customers requirements.
Standard sizes of core bits which are available are: 1" (25mm) , 2" (50mm) , 3" (76mm) , 4" (100mm) , 6" (150mm).
Universal Engineering Works do not manufacture, but can supply Tricone Rock Roller Bit:
Both Milled Tooth Rock Roller Bits and Tungsten Carbide Rock Roller Bits (TCI Bit)are available.
Commonly known as R R Bits, we have bits of all sizes viz. 2 7/8" , 3 7/8", 4 " , 5" , 6", 9 7/8" , 11 ", 12 " , 13 " , 15" , 17 " etc.
We keep in stock new, used, old and fully reconditioned Rock Rock Roller Bits of various make.
For Diamond Core Drilling smaller sizes upto 5 (approx) are used for non coring.
For Tubewell drilling larger bits are used like: 8 , 12 1/4 , 17 etc
Impregnated Diamond Drilling Bit consist of small diamonds or diamond powder, distributed throughout the bit crown to a specified depth. During use, the matrix, in which diamonds are impregnated is worn out constantly, ensuring the new, sharp diamonds become active. The diamond size of these bits are very small, thus these diamond drilling bits are used in medium hard to very hard and broken formations.
UEW manufactuer standard 8mm matrix depth of impregnation. Greater depth of impregnated core bits are also manufactured.
| MATRIX | FORMATION | BIT COLOUR | BIT TYPE |
|---|---|---|---|
| EXTRA HARD MATRIX | For drilling in abrasive formations | GREY | For Surface Set Core Bits and Diamond Impregnated Core Bits |
| MEDIUM HARD MATRIX | General purpose matrix bits for medium hard rock | RED | For Surface Set Core Bits and Diamond Impregnated Core Bits |
| SPECIAL MATRIX | General purpose bits for hard to very hard ground | BLUE | Diamond Impregnated Core Bits |
Tungsten Carbide Core Bits (T C Bits), like diamond core bits, drills for cores but use tungsten carbide as its cutting medium. It cuts the same size core as that by a diamond bit & fits into the same size core barrel.
These bits have octagonal tungsten carbide inserts as cutting edge. The quality of tungsten carbide tip has been specially chosen for rotary core drilling to give high wear resistance.
UEW T.C. Bits can be used in soft to medium hard or comparatively less abrasive formations. These can be used as tools for cleaning out casing. These bits can replace the more expensive diamond drill bits when used for drilling in non consolidated formations.
UEW manufactures complete range of following TC Bits as per DCDMA / BRITISH / WIRELINE Core Drilling Standards
