Secoroc MH – extra long life in medium hard rock formations
Conical or chisel shaped carbide buttons and very little cone offset allow this bit to drill fast for long hours in medium hard rock formations, including hard limestone, dolomite and shale.
Secoroc H – for hard rock formations
Tough, fracture-resistant, ovoid, and ogive-shaped carbide buttons and reduced offset make this bit ideal for heavyweight, hard rock applications. Good load distribution thanks to heavy cutter set and full bottom hole coverage.
Secoroc VH – for very hard formations
Tough ovoid carbide buttons, zero offset and full bottom hole coverage combine to allow long hours of drilling in weighty hard rock applications. Positioned to cover the bottom of the hole, the nose and inner row button of the hole are ovoid-shaped with low projection.
Designed for very hard, abrasive drilling
Advanced research and development has lead to new proprietary carbide grades that provide greater wear resistance than previous grades – leads to longer time drilling. We also improved the cutting action on the bottom of the hole through greater efficiency of forces to crush and fracture the rock. Combined these features lead to longer hours of drilling in hard-rock, in high weight-on-bit applications.
Sealed bearing journal
The PrimO is an advanced, double-seal, bearing system that maximizes grease retention during long hours of high loading. Tucked shirt tail reduces heat generation near seal, extending seal life. Excluder protects seals from cutting debris, making this bearing system the most reliable of its kind.
Maximum gage protection
Hard, round top carbide inserts on gage and wear resistant inserts on bevel slow down gage wear.
