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).

- high-speed steels ( HSS)
high-speed steels ( HSS)
Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.
- twist drill
twist drill
Most common type of drill, having two or more cutting edges, and having helical grooves adjacent thereto for the passage of chips and for admitting coolant to the cutting edges. Twist drills are used either for originating holes or for enlarging existing holes. Standard twist drills come in fractional sizes from 1¼16" to 11¼2", wire-gage sizes from 1 to 80, letter sizes A to Z and metric sizes.
- wear resistance
wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
