Dedicated Key Bits Optimize Fatigue Life Prediction of DrillMeister Drill Bodies

Tungaloy has increased its size options of KHS key bits that are developed for easy management of DrillMeister drill body service life.

DrillMeister exchangeable-head drill system combines the precision of solid carbide drills with the flexibility of modular tooling. For users to reap the maximum benefits of this innovation, accurate management of the drill body service life is vital. Conducting release torque tests for the drill bodies is an effective way to predict the fatigue life while eliminating the risk of loose connections and losing the drill heads in the machines. The KHS key bits enable easy measuring of the drill head release torque: the bits can simply be attached to commercial torque screwdrivers equipped either with manual adjustable preset torques or with a digital display, which allow accurate torque measurements.

Two new key sizes have been added: KHS-TID6-9.99 covers the drill diameter range from 6.0 to 9.9 mm (.236″ to .340″), while KHS-TID20-25.99 from 20.0 to 25.9 mm (.787″ to 1.020″). In addition to the key size that already exists for 10.0 to 19.9 mm (.394″ to .783″), these three key sizes cover the diameter range from 6.0 mm to 25.9 mm of the DrillMeister drill heads.

Related Glossary Terms

  • fatigue

    fatigue

    Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.

  • fatigue life

    fatigue life

    Number of cycles of stress that can be sustained prior to failure under a stated test condition.

  • modular tooling

    modular tooling

    1. Tooling system comprised of standardized tools and toolholders. 2. Devices that allow rapid mounting and replacement of tools. Commonly used with carousel toolchangers and other computerized machining operations. See toolchanger; toolholder.
