Product Description

The Precision Twist S209 drill bit is a long-length, black oxide coated, small Morse taper shank drill bit. It can drill to a depth up to four times the diameter of the drill size. The shank diameter is the same as the drill size. The longer length offers more flexibility in thicker materials or harder to reach locations.

The S209 series has a type N flute form, with a regular helix angle of 21 to 34 degrees and a conventional point design that is the most commonly accepted standard for drilling holes in a variety of material, such as metal, wood, and synthetics, with best performance in steel and cast iron. Black oxide improves lubricity, resists corrosion, and will not chip or flake off. Black oxide also helps to prevent buildup and welding of material on the tap’s cutting edge when working with iron and steel.

The Morse taper is a shank that is tapered from one end to another. The taper of the tool fits into the taper of the toolholder. The friction between the surfaces provides a secure holding systems and accurate placement of the tool. A drift pin is knocked into the slot at the tang to remove the tool.

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. They are made to ANSI (fractional sizing) industry standards, which ensure that drill bits around the world, confirm to the same specifications.

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.
