Diameter (mm) Diameter (mm) Cutting Condition Selection Control cutting force for low rigid machine The following table shows the relation between edge treatment width and cutting force. If a problem caused by
cutting force occurs, reduce either the feedrate or the edge treatment width.

High speed machining
recommendation When there is surplus capacity with enough machine power and rigidity drilling at normal recommended cutting conditions, we recommend higher drilling speeds. Wear example
f Flank face g Margin f Rake face Vc=60m/min Vc=120m/min Work material: C50 (230HB) Cutting data: f = 0,3 mm/rev d = 50mm oc Tool life: 600 holes (Cutting length : 30m)
Explanation of Margins (Difference between single and double margins)
Single Margin (2 guides: circled parts) D Double Margin (4 guides: circled parts)
Technical Guidance Shape used on most drills 4-point guiding reduces hole bending
and undulation for improved stability and accuracy during deep hole drilling.
