CrazyMill Chamfer - four complementary
chamfering and deburring tools

• Quick machining through high cutting speeds and feed rates
• No unclamping for back chamfering or deburring

• Special tungsten carbide: high fracture toughness and thermal shock resistant
• Protection against wear due to high-performance coating

• Clear defined and simple deburring or chamfering process

• Highest surface quality of the chamfer because of a positive cutting geometry and high number of cutting edges
• Clean deburring because of sharp cutting (no secondary burrs)

CrazyMill Frontchamfer for chamfering and deburring

• Diameter d1 of 1.0 mm to 6.0 mm (.0393" to .236")
• Allows the forward deburring of holes from 0.4 mm (.0157") (d2 min = 0.3 mm (.118"))
• Chamfer of 90°
• 4 to 6 teeth (depending on the diameter) for good surface quality
• The tool does not have a pointed tip but a blunt cone shape and can therefore deburr the smallest offsets
• Also suitable for thread deburring
• Positive cutting geometry guarantees excellent surface quality

CrazyMill Backchamfer – back edge deburring and hole deburring

• Diameter d1 of 0.36 mm to 5.7 mm (.0142" to .224")
• Suitable for back deburring of holes with a diameter of 0.4 mm – 6.0 mm (.0157" to .236") and higher
• Chamfer of 90°
• 3 to 6 teeth (depending on the diameter) for good surface quality
• Back hole deburring, deburring of edges and difficult-to-access locations without unclamping of the part (thread deburring as well)
• Two versions: for deburring depths of 3 x d and 5 x d
• Positive cutting geometry guarantees excellent surface quality

CrazyMill Doublechamfer – front and back deburring in a single clamping

• Diameter d1 of 0.9 mm – 5.7 mm (.0354" - .224")
• Suitable for back deburring of holes with a diameter of 1.0 mm – 6.0 mm (.0393" to .236") and higher
• Chamfer of 90° front and back
• 4 to 6 teeth (depending on the diameter) for good surface quality
• Front and back deburring and deburring in difficult-to-access spots as well as edge deburring – in one single clamping
• Two versions: for deburring depths of up to 3 x d and up to 6 x d

CrazyMill Radiuschamfer – use in complex shapes in hard-to-reach locations

• Diameter d1 of 1 mm– 6 mm (.0393" to .236") (ball diameter)
• 3 to 6 teeth (depending on the diameter) for good surface quality
• Usable cutting range of 300° for high accessibility
• Positive cutting geometries for a good sharp cut even in viscoplastic materials prevents secondary burrs
• For front and back deburring
• Can replace thermal deburring or explosive deburring

• Four different, complementary milling tools for chamfering and deburring: unlimited possibilities for specific applications
• Suitable for deburring of metals such as low-alloy and high-alloy steels, stainless steels, structural steel, titanium and titanium alloys, cast iron, copper, aluminum and hardened steels up to 55 HRC.
• All chamfering and deburring tools are made of tungsten carbide and have high-performance coating
• For the smallest machining in the highest quality
• High feed rates possible
• Best surface quality of machining guaranteed
• Diameter ranges are matched to the CrazyDrill drilling program
