Tricone Bits
Tundra is an exclusive distributor of Cenerg Global Tools for open pit mining and construction applications. Cenerg has been a leading manufacture of rotary bits since 2012 and is the fastest-growing bit manufacturer globally. At an output of 2500 bits per month, Cenerg has a strong customer base spread across 20 countries. Tundra and Cenerg are well equipped to respond to our customer's unique drilling challenges by offering a wide range of products with short delivery times.
Ranges of rotary drill bits cover blast hole, water well, raise boring, construction, oilfield, workover, exploration and directional drilling applications. Bit sizes range from 2 3/8" (60 mm) to 17 1/2" (444 mm) in milled tooth and tungsten carbide insert types. The selection of cutting structures we stock range from steel tooth for soft formations and tungsten carbide for hard rock formations. Either cutting structure is available in mud rotary and open air bearing packages.
​
In addition to ISO9001:2015, API Spec 7-1 Certifications, Cenerg's 97,000 sqft manufacturing facility is certified by the American Petroleum Institute for quality management system conforming to API Q1. In-house forging and heat treatment reduce supply chain issues. Only German and North American tungsten carbide impacts and inserts are used.​Cenerg holds the #1 market share for mining in Australia and Chile.
Blast Hole Bits
For use in less abrasive softer formations with compressive strength ranging between 90 – 150 Mpa, such as shales, limestones, carbonates and most metamorphic formations. Cutting profile: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.
For use in moderately abrasive consolidated formations with compressive strength ranging between 120 – 200 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic formations. Cutting profile: These bits are characterized by moderately spaced wedge chisel or conical inserts with medium projection. This configuration promotes good penetration rates in medium hard and moderately abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.
For use in abrasive consolidated formations with compressive strength above 200 Mpa such as taconite, quartzite and banded iron formations Cutting profile: These bits are characterized by closely spaced conical or spherical inserts with medium to low projection. This configuration promotes good penetration rates in hard, consolidated and very abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance
Industrial Bits
Water Well Drilling, Construction & Geotechnical
These tooth bits are designed for optimum performance in formations of low compressive strength ranging below 70 MPA Cutting profile: These soft formation bits are designed with long, slim, strong, widely spaced teeth with intermittent deletions to permit deep penetration in the formation with comparatively light weight on bit.
These tooth bits are designed for medium to hard formations with compressive strength ranging between 70 - 100 MPA Cutting profile: These bits have higher capacity bearings, more closely spaced teeth with increased tooth angles and more gage surface for resisting wear to allow the use of heavier weights required to effectively drill hard formations.
