Serie 8 MT cutters

Series 8 shaft cutters are commonly used for 24” to 27” diameter bores. They are the smallest saddle mounted cutters manufactured by Atlas Copco Secoroc and have random cutting structures to optimize the machine drilling and cleaning capabilities.

Features and benefits
• Pressure compensated system to reduce stress on the sealing elements, during deep drilling.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Manufactured with high durability hardfacing material to prolong the service life of the cutters.
• Mounting system is compatible with MT cutters for field interchangeability to match any drilling formation.
• Random cutting structures allow a single cutter type to be used in all position s to minimize inventory.
• Load pin retention system that acts a fail-safe mechanism to prevent the loss of cutters down the hole.

Serie 12 MT cutters

Series 12 cutters are used for drilling holes 48” to 120” in diameter. They feature a high capacity bearing roller-ball-roller design, with a sealing system designed for maximum protection. The MT cutters are used in soft to medium formations such as siltstone, chalk, and shale. These cutters are paired as required to optimize the cutting structure.

Features and benefits
• Pressure compensated system to reduce stress on the sealing elements, during deep drilling.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Manufactured with high durability hardfacing material to prolong the service life of the cutters.
• The mounting system is compatible with the TCI cutters for field interchangeability to match any drilling formation.
• Load pin retention system that acts a fail-safe mechanism to prevent the loss of cutters down the hole.
• Special hardfacing material on teeth to improve wear properties.

Serie 12 TCI kerf cutters

Series 12 cutters are used for drilling holes 48” to 120” in diameter. They feature a high capacity bearing roller-ball-roller design, with a sealing system designed for maximum protection. Kerf cutters are ideal for drilling in hard ground where machine capabilities are limited.

Features and benefits
• Pressure compensated system to reduce stress on the sealing elements, during deep drilling.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Manufactured with high durability hardfacing material to prolong the service life of the cutters.
• Mounting system is compatible with the MT cutters for field interchangeability to match any drilling formation.
• Kerf cutters generate larger cuttings to maximize the load capabilities of the machines.
• Load pin retention system that acts a fail-safe mechanism to prevent the loss of cutters down the hole.

Serie 13 MT cutters

Series 13 cutters are used for drilling holes 47” to 120” in diameter. MT cutters come in pairs to maximize the cutting radius profile of the bit. The bolt on system makes them easy to replace during field operation, to reduce down time during cutter replacement and to increase production.

Features and benefits
• Integral seal retainer for fewer moving parts for increased reliability.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Bolt-on mounting system to make it easier to remove more maintenance of the cutter.
• Compatible with the TCI cutter mounting system for field interchangeability to match any drilling formation.

Serie 13 TCI random cutters

Series 13 cutters are used for drilling holes 47” to 120” in diameter. Specially designed random cutting structure designed for the toughest conditions.

Features and benefits
• Integral seal retainer for fewer moving parts for increased reliability.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Bolt-on mounting system to make it easier to remove more maintenance of the cutter.
• Compatible with the MT cutters for field interchangeability to match any drilling formation.
• Random cutting structures allow a single cutter type to be used in every position to minimize inventory.

TCI center cutters

Center cutters are used to cover the center of the shaft. Their greater cone angle allows them to cut rock at the center of the shaft with maximum rolling efficiency.

Features and benefits
• Pressure compensated system to reduce stress on the sealing elements, during deep drilling.
• Sealed roller-ball-roller to protect bearings for maximum performance.
• Manufactured with high durability hardfacing material to prolong the service life of the cutters.
• Mounting system is compatible with the MT cutters for field interchangeability to match any drilling formation.
• Random cutting structures allow a single cutter type to be used in all position s to minimize inventory.
• Load pin retention system that acts a fail-safe mechanism to prevent the loss of cutters down the hole.
