Extra rigidity in deep pockets – Choose short flute length with neck relief.
Medium-to-deep cuts – Order standard, long or extra-
long flute length and reach.
Finishing passes – Order extra-long flute length.
Neck relief – Better clearance in deeper cavities,
easier machining against tight walls.
M706
For hardened steels and general finishing applications. The first-generation
Omega-6 design offers reliable tool life in hardened steels.
The M706 is a proven winner in wet or dry machining of materials up to 62 HRC.

A half-century of know-how from our hands to yours.
Any machinist worth his salt will tell you: there’s no substitute for the deep knowledge that comes with decades of making tools that do the job right.
Sure, we use the same advanced technologies and CNC precision to make all our cutting tools. But it’s that know-how that makes IMCO burs
work harder and many times longer than burs made by anyone else. Some call it craftsmanship. We call it knowing what we’re doing.
Bur Shapes
IMCO carbide burs are offered in an array of shapes,
fluting patterns and lengths suitable for all types of deburring
applications. Choose the shape that conforms to your work
piece using the diagram below as a guide.
