Rotary Drill Bit Series

1.CN 25 – CN 31 Series Very Soft Formation Rotary Drill Bits

Design features: Large diameter and widely spaced chisel
or sharp conical carbide insert with high projection.
Small flat inserts placed in between, on gage and inner rows to prevent cone shell erosion. Laser hard faced spot deposits to arrest steel erosion. Additional flush space on shirttail for quick evacuation of cuttings.

Benefits: Vibration free drilling resulting in maimum penetration rates in very soft formation.
Applications: suitable for Sand, Mudstone, Sandstone type sedimentary formations with low compressive strenghs of 20 to 60 Mpa

Rotary Drill Bit Series

2.CN 37 – CN 44 Series Soft Formation Rotary Drill Bits

Design features: Large diameter and widely spaced chisel or sharp conical carbide inserts with high projection. Small flat inserts placed in between, on gage and inner rows to prevent cone shell erosion. Hard faced cone shell to delay erosion and exposure of active inserts.

Benefits: High penetration rates in soft formation along with vibration free drilling.
Applications: Suitable for Shale, Lime stone, Sandstone, Gravel – Soft formations with compressive strengths of 50 to 110 Mpa.

Rotary Drill Bit Series

3.CN50 – CN 60 Series Medium Hard Formation Rotary Drill Bits

Design features: Moderately spaced conical inserts with medium projection. Doublerow gage protection inserts. Hard metal deposit on nose area to protect against cone shell erosion.

Benefits: Good penetration rates and longer life in medium hard and moderately abrasive formation. Longer bearing due to Smooth Drilling.
Applications: Suitable for Granite, Marble, Hard Sandstone – Medium Hard formations with Compressive Strengths of 90 – 150 Mpa.

Rotary Drill Bit Series

4.CN 64 – CN70 Hard Formation Rotary Drill Bits

Design features: Closely spaced conical or spherical Inserts with medium to low projection. Hard metal deposit on nose area to protect against cone shell erosion.

Benefits: Good penetration rates in hard, consolidated and very abrasive formation. Longer bearing due to Smooth Drilling.
Applications: Suitable for Dolomite, Granodiorite, Quartzite, Magnetite, Banded Hematite Quartzite. Formation of 150 to 250 Mpa. and banded iron and abrasive consolidated formations with compressive strengths of above 200 Mpa.

Rotary Drill Bit Series

5.CN 74 – CN 80 Very Hard Formation Rotary Drill Bits

Design features: Closely spaced conical or spherical medium to low projection crack resistant tough carbide Inserts. Load balanced layout of inserts.

Benefits: Stable penetration rates in very abrasive formation. Longer bearing life due to smooth drilling.
Applications: Quartzite, Taconite, Banded Iron. Very hard grade formations of 260 to 400 Mpa.

Rotary Drill Bit Series

6. Milled Tooth – Soft, Medium and Hard Formation

Design features: Aggressive and robust teeth protected with Tungsten carbide hard facing for extended performance.

Benefits: Good penetration rates in unconsolidated and unfavourable rock conditions.
Applications: Clay,Sand,Sandstone, Gravel,Silt stone, Mud Stone formations Compressive strengths upto 100 Mpa.

Air to Bearing Bit features & Sealed Bearing Bit features

Bearing Types

1. Open bearing – Air Circulation

In this configuration an air passage is provided to the bearing area. The compressed air cools and lubricates the bearings and blows away any drilling debris extending the life of the bearing.
This bearing configuration is commonly used in Blasthole Mining applications

Bearing Types

2. Open bearing – Air, Mud or Foam Circulation

The standard open roller bearings are without a seal or an air passage. They are ideal for drilling shallow holes, in the hundreds of feet with either foam or mud circulation. These bearing configurations are commonly used in Water Well applications.

Bearing Types

3. Semi-Sealed bearing – Air Circulation

Semi-Sealed bearings for air circulation are similar to Open Air bearings, only difference being the bearing pack protected with an O- Ring Seal. The lubricant is filled into the bearing and sealed off. This prevents ingress of dirt into the bearing system and leakage of grease. This configuration is used for Mining applications with heavy water injection and ground water conditions.

Bearing Types

4. Sealed Journal bearing – Air & Mud circulation

In Sealed Journal bearing the Rollers inside the cone are replaced by a Floating Bush made out of special alloys which is silver plated. The bearing Pack is protected with an O-Ring Seal. The bearing lubrication and pressure compensator system is built in. The Floating Bush is highly resistant to heat and galling. Consequently these bearings are very durable and suitable for Mining, Raise Boring, HDD applications

Bearing Types

5. Sealed friction bearing – Mud circulation

In bearings for Small Diameter Bits instead of the Floating Bush the internal surface of the Cone is silver plated using a special process. This design enables bearing size to be increased in relation to the diameter of the Bit enhancing its durability. This bearing design finds application in Reverse circulation and Waterwell drilling applications

Bearing Types

6. Sealed roller bearing – Air & Mud Circulation

While sealed roller bearings have some of the features of Open to Air bearings, the bearing pack is protected with an O- Ring Seal and has lubrication and pressure compensator system built in. This prevents ingress of dirt into the bearing system and leakage of grease. This configuration is used for Mining, Exploration applications
