ENGINEERING DATA

Selection data for a technical quotation.

Use the published chart and series attributes where available. For a safe recommendation, send the fields below; BOFA will return the matching geometry, insert and cutting-condition card for your machine.

Decision field	What to provide or verify	BOFA quotation output
Published series attributes	BT40 / BT50 · FMB22-FMB40 · Face Milling · 45-200 mm	Confirm the exact model and size chart row
Workpiece material and hardness	Exact grade plus measured HRC or HB; include stainless, cast iron, aluminium or mould-steel condition	Recommended grade, geometry and coating
Speed, feed and depth	Target RPM or cutting speed, feed units / fz / Vf, axial ap and radial ae	Condition card for the selected diameter and operation
Geometry and reach	Diameter or ball radius, flute count, cutting length, overall length, helix and coating	Compatible standard or custom configuration
Insert and interface	For indexable tools: body model, insert code, screw and wrench. For solid tools: spindle taper, shank, holder and gauge length	Compatibility check before ordering
Tolerance and runout	Required tool-tip runout and diameter / length tolerance	Achievable value confirmed on drawing or datasheet
Cooling and maximum engagement	Dry, air blast, MQL or flood coolant with pressure / flow; state required machining depth	Safe engagement guidance; do not infer a limit from cutting length alone
