KEO ZErO flute countersink and deburring tools are simple, all-purpose tools made of Cobalt that provide flawless countersinking and deburring. The chatter-free cutting action requires minimal power. The microsmooth CNC precision ground construction produces clean, smooth cutting without smearing on a variety of materials. The tool especially excels in countersinking or deburring holes in aluminum, plastics and other nonmetallics. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. 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. 82 degree angle.

Union Butterfield 4603 Series High-Speed Steel Single-End Countersink, Uncoated (Bright) Finish, Single Flute, 60 Degrees, 1/4" Shank Dia, 3/8" Body Dia.

Model: 4710790   |    Mpn: 46033/8X60   |    Ean: 0698464074776   |    PartNumber: 46033/8X60   |   Asin: B003JY6WCO

The Union Butterfield 4603 series high-speed steel single-end countersink with an uncoated (bright) finish creates a 60-degree conical opening that can be used for holding material between machine centers. The single flute quickly cuts through material and has reduced vibration at higher speeds compared to multiple flutes. It is suitable for cutting small holes. High-speed steel (HSS) provides hardness for wear resistance. The uncoated finish has no additional surface treatment or coating. The tool has a single cutting end and a round shank that accommodates most drill chucks.

Countersinks are fluted cutting tools that cut a conical or gradually widened opening for a hole into the surface of a workpiece, which provides a seat for a screw or rivet head. They are also used to create center holes for a machine center, deburr surfaces, and enlarging existing holes. The countersink's body diameter should be the same size or larger than what is being countersunk.

Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.

Features

  • Creates a 60-degree countersink, which can be used for holding material between machine centers

KEO 55794 Solid Carbide Single-End Countersink, Uncoated (Bright) Finish, 6 Flutes, 82 Degree Point Angle, Round Shank, 1/4" Shank Diameter, 3/8" Body Diameter

Model: 55794   |    Mpn: 55794   |    PartNumber: 55794   |   Asin: B00947W3DW

KEO 6-flute line of countersinks are companions to our single flute countersinks and our 3- and 4-flute center reamer line. As a rule, the more edges per revolution, the greater amount of material that may be removed. We have designed the 6-flute tools with staggered cutting edges. 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. 82 degree angle.

KEO 55816 Solid Carbide Single-End Countersink, Uncoated (Bright) Finish, 6 Flutes, 100 Degree Point Angle, Round Shank, 1/4" Shank Diameter, 3/8" Body Diameter

Model: 55816   |    Mpn: 55816   |    PartNumber: 55816   |   Asin: B00947XUP2

KEO 6-flute line of countersinks are companions to our single flute countersinks and our 3- and 4-flute center reamer line. As a rule, the more edges per revolution, the greater amount of material that may be removed. We have designed the 6-flute tools with staggered cutting edges. 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. 100 degree angle.
