Precision Twist 209 High Speed Steel Taper Shank Drill Bit, Black Oxide Finish, Morse Taper Shank, Spiral Flute, 118 Degree Point Angle, 1 5/16" Feature

• Long length drill bits (also called taper length), have longer flutes and overall lengths than Jobber drill bits
• Morse taper shank, for a secure and accurate tool-holding system
• 118-degree conventional point angles for general drilling applications
• Black oxide finish, improves lubricity, resists corrosion, and will not chip or flake off
• High-speed steel (HSS), for use on a wide variety of materials

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. They are made to DIN 1897 industry standards (metric sizing), which helps ensure that drill bits around the world, conform 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.

The Precision Twist R56 Jobber-length, uncoated, general-purpose, round shank drill bit drills holes into a wide variety of metals and synthetic materials with best performance with steel, stainless steel, cast iron, titanium, and nickel. It can drill to a depth up to four times the diameter of the drill size. Flute length is three inches, overall length is six inches, with a half inch, reduced shank.

Combination black oxide and bright finish improves lubricity, resists corrosion, and will not chip or flake off. Black oxide also helps to prevent buildup and welding of material on the cutting edge when working with iron and steel.

Reduced shanks are smaller than the drill diameter, so they can drill holes larger than the typical chuck capacity. These are sometimes called Silver & Deming drills; they used to be made by Silver & Deming in the late 1800’s, but nowadays, it’s come to mean any reduced shank twist drill bit.

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 can be used in hand operated drills, standalone drill presses or a machine tool called a lathe, to drill a hole. 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 the chips up and away from the cutting edge. They are made to ANSI standards, which ensure that drill bits around the world, confirm to the same specifications.

Together, the Precision and Dormer brands represent a new, streamlined organization that provides a strong North American tool brand for high productivity Carbide and HSS drill and tap products. Precision was founded in 1952 in Crystal Lake, Illinois. Dormer tools, was founded in 1913 in Sheffield, England, is known worldwide for innovative metalworking products.

Precision Twist M40CO Cobalt Steel Stub Drill Bit, Gold Oxide Finish, Round Shank, Spiral Flute, 135 Degree Point Angle, 1/8" (Pack of 12)

Precision Twist M40CO Cobalt Steel Stub Drill Bit, Gold Oxide Finish, Round Shank, Spiral Flute, 135 Degree Point Angle, 1/8" (Pack of 12) Review

Precision Twist M40CO Cobalt Steel Stub Drill Bit, Gold Oxide Finish, Round Shank, Spiral Flute, 135 Degree Point Angle, 1/8" (Pack of 12) Feature

• High-speed steel (HSS) containing cobalt is a good combination of toughness and hardness, for use on drilling through hard substances
• Gold oxide, retains cutting fluid and prevent chip to tool welding
• 135-degree split point angle is self-centering, reduces walking, good for hard material and reduces pressure on cutting edges
• Short-length, for better rigidity and increased strength
• Round shanks, for use on a variety of tool-holding systems

The Precision Twist M40CO jobber-length drill bit is a 135-degree split-point, heavy-duty, round shank drill bit made of high-speed steel and cobalt with a gold oxide finish. For best use drill with hardened, tempered alloy steel, stainless steel, nodular graphite, malleable cast iron, titanium, nickel and hard material-cemets. It is suitable for drilling to a depth up to two-and-a-half times the diameter of the drill. The shank diameter is the same as the drill size.

The M40CO series has a type N flute form (a regular helix angle of 21 to 34 degrees). The gold oxide is a low temperature heat treatment which reduces grinding stress within the tool, and has an appealing, easy-to-identify gold color. Gold oxide is commonly used to identify cobalt steel tools. Spiral flutes act as a passageway for chip extraction from the hole and for coolant to enter the hole. Right-hand twist brings chips up and away from the cutting edge.

Made of HSS with cobalt, which is many times harder/stiffer than 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.
