EAP300R / EAP400R Indexable Cutter Bar

BOFA EAP series cutter bars use replaceable indexable inserts for reliable shoulder milling, slotting, contour machining and other practical milling operations. Choose the matching EAP300R or EAP400R configuration according to the required diameter, shank and insert type.

Series configuration

Series	Compatible insert	Diameter range	Shank range	Edge count
EAP300R	APMT1135	D10-D30 mm	C10-C25 mm	1T-4T
EAP400R	APMT1604	D25-D40 mm	C20-C32 mm	2T-3T

Applications and insert selection

The EAP cutter bar range supports roughing, finishing, cavity machining, concave-groove machining, step surfaces and profile-style operations. Matching inserts are selected according to the workpiece material; the cutter bar and inserts are supplied separately.

Model and size charts

Complete product models, insert codes, shank diameters, cutter diameters, overall lengths and edge counts are provided in the EAP300R and EAP400R specification charts below. Contact BOFA with the material, operation and required dimensions for a compatible recommendation.

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	EAP300R / EAP400R · APMT1135 / APMT1604 · D10-D40 mm · 1T-4T	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
