Technical information and advice about mine drills and tools
CANUN’s technical representatives and engineering staff offer consultation services on mining drill equipment and machinery. The company’s library of drill technical information is extensive and includes the Drill Doctors Handbook, a manual of established practices and practical suggestions for maintenance and repair of jackleg, stoper and sinker rock drills.
CANUN also delivers training courses in drill repair and maintenance, so on-site staff can undertake work reducing costs and downtime.
Drill repair and refurbishment services for mines

As well as repairing CANUN 260B drills, the company also services all Boart S250 and Gardner Denver S83 rock drills.
High-quality materials for a long drill life
As part of CANUN’s commitment to manufacturing durable drills with a longer wear life, all CANUN products are made using the best material available and to the highest quality standards in the industry.
Major components such as cylinders, backheads, frontheads, handle adapters and clevis body sections are made from high-grade forged steel. For parts that require heat treatment, methods are employed to produce the optimum combination of toughness and wear-resistance.
Bronze materials are used for certain applications due the metal’s quality and strength, and CANUN manufactures specialised and oversize parts for specific applications, to extend the life of the high-cost components.
CANUN is committed to providing drill quality and longevity, which is evident in the following examples:
- The cylinder is made from an alloy steel forging and heat-treated so the internal bore is highly wear-resistant and the body is dent-resistant. The cylinder lug bushing of a CANUN cylinder is also thicker than standard models, to prevent cracking
- A unique feature of CANUN cylinders is that they are used for the jackleg, stoper and sinker drills. By changing the position of the exhaust plug, a jackleg cylinder can be converted into a stoper cylinder, and vice-versa. This flexibility reduces inventory requirements
- Oversize cylinder lug bushing for both the jackleg and stoper cylinder prolong the life of the cylinder
- CANUN jackleg backheads are strengthened in the tapered area to reduce cracking. The high-quality alloy steel used in the forging resists denting and increases service life due to its greater wear resistance
- CANUN a697 handle adapters have a thicker section in the retract valve area for improved dent resistance
- CANUN’s shop repair tools are available to assist in drill repair and refurbishing of parts
- CANUN offers a cylinder re-chroming service, with quotes available upon request
CANUN rock drills and service parts was founded in 1981 and has grown to be one of the major suppliers of equipment to the Western Hemisphere. This achievement and excellent reputation came from providing drills that increase production and lower operating costs.
CANUN drills and parts are shipped worldwide to countries that include Canada, US and South America.
