Your Go-to Jobber Drill - the Precision Twist Drill HX

The Precision Twist Drill HX delivers quality and reliability. 
​The Precision Twist Drill brand has been around since 1952 and its quality and consistency continues with the HX series of High Speed Steel jobber drills. Recognized throughout the cutting tool section for its unique purple/bronze oxide finish, users can easily identify their go-to jobber drill.

Combining the strength of HSS with a 135° split point, users achieve increased efficiency with reduced cost per hole. The unique HX design reduces thrust requirements, resulting in improved cutting action and reduced walking.

Compared to other high speed steel, heavy duty jobber drills, the Precision Twist Drill HX delivers up to 70% more holes in medium strength materials. The versatility of the industry's "Go-to Jobber Drill" extends beyond medium strength materials, delivering 18% more holes in high strength materials and up to 30% more holes in low strength materials.

With optimal flute geometry for effective chip evacuation and its unique purple/bronze oxide coating for increased wear resistance, the Precision Twist Drill runs faster and more efficient. The HX is available in HX10 (fractional sizes),HX15 (letter sizes) and HX18 (wire gauge sizes).

Join those who already experience the reliability of the Precision Twist Drill HX jobber drill and make it your "Go-to Jobber Drill".
