the M525 series is extremely versatile. It optimizes tool performance in many materials and in many application environments,
from short runs in job shops to long production runs.
Helps prevent corner chipping.
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.

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.

BUR SETS
Convenient sets with varying assortments of our most popular burs. Double Cut and Standard Cut sets available.
End-cut options:
Plain End
Plain end – Also called “safe end” tools.
Use for edge routing or when the end of
the router will not come in contact with the work piece.
Bur End Cut
Use for bottom cutting to leave a smooth,
even surface with a square corner.
End Mill End Cut
Use for bottom cutting for a smooth
bottom surface with a square corner
Drill Point End Cut
Use before the routing operation to
plunge through the work piece.
NOTE: Take special care while plunging
that the router end does not come in
contact with the workholding apparatus.
