Description

Precision Twist 209 High Speed Steel Taper Shank Drill Bit, 1 5/8"
Size:1-5/8" The Precision 209 drill bit is a long-length, black oxide-coated,
Morse taper shank drill bit. It can drill to a depth up to four times the
diameter of the drill size. The longer length offers more flexibility in
thicker materials or hard-to-reach locations. The 209 series has a type N
flute form, with a regular helix angle (21 to 34 degrees) and a conventional
point design that is the most commonly accepted standard for drilling holes in
a variety of materials, 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 tool-holder. 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.
