Key Features

  • Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
  • Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications
  • Round shanks allow use with a wide variety of toolholding systems
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • Standard length

Product Description

The Precision Twist D33F jobber-length, uncoated, heavy duty, round shank drill bit drills holes into a wide variety of metals and synthetic materials. It can drill to a depth up to three times the diameter of the drill size. The shank diameter is the same as the drill size.

The D33F series has a type N flute form, with a standard spiral (21- to 34-degree helix angle) have best performance for drilling into copper and synthetic materials. The uncoated finish helps increase chip flow in soft materials. Round shanks allow use with a wide variety of tool holding systems.

Made of carbide, a metallic carbide composite with binder material, many times harder/stiffer than high-speed steel (HSS), will hold an edge longer, and will deflect less than HSS. These are also more resistant to heat than HSS. These qualities allow it to run at higher speeds and feeds. They are made to ANSI (fractional sizing) industry standards, which ensure that drill bits around the world conform to the same specifications.

Drilling, or hole making, is the most common metalworking operation in the world. Twist drill bits are the most common type of drill bit used. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. These drill bits have a right-hand twist that brings chips up and away from the cutting edge.

Precision manufactures machine tools under the following brands: Precision Twist, Precision Dormer, and Union Butterfield. They have locations around the world, and provide tools adhering to ANSI, NAS, and DIN standards.
