Certain ground conditions can be difficult for drillers, so customized drilling equipment and tools are the key to improving drilling performance. The HERO™ Abrasive series was developed to address the challenges of drilling in abrasive rock types. This line arises from the very popular HERO™ series, introduced in 2008 and renowned for its excellent penetration/lifetime ratio. The line’s Abrasive version gives you the same benefits in a new variety of grounds.
Â
This specialized line features core bits with redesigned components that provide increased resistance to abrasion. Their reinforced diameter helps preserve the internal and external diameters. When used with a recommended drilling additive program, drilling performance in abrasive ground is optimized.
Â
The series includes four hardness levels (5, 7, 9 and 11) covering a range from medium hard abrasive ground (between 5.0 and 6.5 on Mohs scale) to very hard abrasive ground such as iron ore (6 to 7.5 on Mohs scale)..
Â
HERO 5 Abrasive
The HERO 5 Abrasive matrix is suitable for a wide variety of grounds and can withstand very abrasive rock formations. Like other core bits in the Hero Abrasive line, it offers excellent reliability, versatility and the same excellent penetration/lifetime ratio as the popular Hero line of core bits. The Hero 5 Abrasive provides consistent cutting ability in changing ground conditions.
Â
- Ideal for ground conditions with a high level of variability
- Works best in soft to medium hard abrasive grounds (between 4 and 6 on Mohs scale)
- 13 mm standard diamond height, also available in 16 mm
HERO 7 Abrasive
The HERO 7 Abrasive matrix is an ideal choice for a wide variety of grounds and will withstand the most abrasive rock formations. It is an all-purpose product that offers great reliability and versatility. It provides the same excellent penetration/lifetime ratio as the popular HERO line of core bits.
Â
- Ideal for abrasive rock formations containing different hardness levels
- Optimizes performance in medium hard to very hard abrasive grounds (between 5.0 and 6.5 on Mohs scale).
- 13 mm standard diamond height, also available in 16 mm and 26 mm Vulcan
HERO 9 Abrasive
Specifically developed to withstand highly abrasive rock formations, the HERO 9 Abrasive matrix is an excellent choice, especially in iron ore. These ground conditions are perfect for keeping this winner sharp in even the toughest areas.
Â
- An excellent choice for abrasive rock formations that include high iron ore content
- Optimizes performance in hard to very hard abrasive ground (between 6.0 and 7.5 on Mohs scale).
- 13 mm standard diamond height, also available in 16 mm and 26 mm Vulcan
HERO 11 Abrasive
The HERO 11 Abrasive is a long lasting and free cutting core bit. It features a special, softer matrix that allows the diamonds to come into contact with the ground very quickly for quicker penetration.
Â
- To optimize its penetration rate and lifespan, regular sharpening with a high pressure feed is recommended.
- Optimizes performance in very hard to extremely hard abrasive ground (between 6.5 and 7.5 on Mohs scale)
- 13 mm standard diamond height, also available in 16 mm and 26 mm Vulcan
