Precision Twist Drill HX High Speed Steel Jobber Bits

The Precision Twist Drill brand has been around since 1952. The brand’s quality and consistency are illustrated with the HX series of High Speed Steel jobber drills. Recognized throughout the cutting tool industry for its unique purple/bronze oxide finish, users can easily identify this drill as their “Go-To” jobber drill.

Combining the toughness of HSS substrate with a 135° split point design reduces thrust requirements and eliminates walking while providing greater strength and rigidity than general purpose drills. Users achieve increased efficiency and better tool life resulting in reduced cost per hole.

Compared to other high speed steel, heavy duty jobber drills, the PTD HX can deliver up to 70% more holes in moderate conditions. The versatility of the industry’s “Go-To” jobber drill extends beyond medium strength materials, delivering 18% more holes in heavy conditions and up to 30% more holes in light conditions.

With optimal flute geometry for effective chip evacuation and its unique purple/bronze oxide coating for increased wear resistance, the PTD 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 PTD HX jobber drill and make it your “Go-To” jobber drill.

The Precision Twist Drill HX is also available in a 29 piece fractional set (sizes 1/16” – 1/2” x 64ths). Find out more online at
