Measuring Big: Lessons From The Oil Industry
 In the world of oil drilling, there are some pretty big things. It's not just the rigs anchored out in the ocean that are huge: Everything that goes along with them seems to get supersized, including the need for gaging.

Air-Actuated Boring Tool Offers In-Process Gaging
An air-actuated boring tool semi-finishes cylinders on the down stroke and finishes on the up stroke. In-process gaging compensates for tool wear to maintain bore accuracy.

Dual-Carbide Technology Addresses Basic Drilling Challenge
A dual-carbide-grade drill has a micro-grain carbide core blended to provide toughness to prevent chipping at the drill's point. Surrounding the core is a second carbide grade that provides hardness needed for wear resistance at the drill's outer edges.

Repetitive Part Cutting: Improve Productivity by Learning Path Error
Significant improvements in speed and accuracy are now possible by using a CNC system that can learn and correct for its path error. Expanding the functions of learning control past specialized machines into general machining is the next step in the evolution. Now learning functions can be applied to free profile machining, drilling and tapping. The benefits of applying learning control come from its ability to correct for path and synchronous error seen in repetitive cycles. Once learning is complete reduced cycle times and increased accuracy result.

Dealing With A Spot Drill’s True Point Position
A spot drill has a 90-degree point angle, which makes it easy to calculate the depth of a hole to be spot-drilled. You simply divide the diameter of the spot-drilled hole.
