Tungaloy Key Bits Improve Drill Body Service Life

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

The DrillMeister exchangeable-head drill system is said to combine the precision of solid carbide drills with the flexibility of modular tooling. According to the company, for users to reap the full 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 enable 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 (0.236″ to 0.340″), while KHS-TID20-25.99 from 20.0 to 25.9 mm (0.787″ 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.
