The R220.88 face milling cutter family from Seco features eight-edged cutting inserts and optimized geometries for extended tool life and reduced cutting forces. The 88-degree lead angle enables smaller inserts to cut larger depths compared to 45-degree lead angle face mills. As a result, these tools can machine close to workpiece side walls and part-clamping systems.

Designed for roughing and semi-finishing applications, the cutters are ideal for cast iron and steel parts. They are made of Idun, a corrosion-resistant stainless steel that offers longevity and durability.

The cutter body’s size-12 insert is available in diameters ranging from 2.00" to 6.00" (50 to 160 mm). The size-16 insert is available from 3.00" to 6.00" (63 to 160 mm). Each diameter is offered in standard and close-pitch variants. The size-12 insert’s maximum depth of cut is 0.35" (9 mm), while size 16 provides a 0.51" (13 mm) maximum depth of cut. Right-hand versions of the cutter body are standard, and left-hand versions are available for systems with dual spindles performing simultaneous milling operations.


  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

  • Rigid Tapping--Sometimes You Need A Little Float

    One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.

  • Taking The Fear Out Of Hard Turning

    To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
