Precision Twist Drill 20925/32 209 Taper Shank Jobber Drill

Description

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 tool-holder. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. The friction between the surfaces provides a secure holding systems and accurate placement of the tool. Black oxide also helps to prevent buildup and welding of material on the tap’s cutting edge when working with iron and steel. Drilling, or hole making, is the most common metalworking operation in the world. A drift pin is knocked into the slot at the tang to remove the tool. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards. Twist drill bits are the most common type of drill bit used. The longer length offers more flexibility in thicker materials or hard-to-reach locations. These drill bits have a right-hand twist that brings chips up and away from the cutting edge. Black oxide improves lubricity, resists corrosion, and will not chip or flake off. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole.
