超硬合金製 3刃エンドミル
Compare solid carbide 3-flute square end mills by cutting geometry, chip evacuation requirements and tool reach. Explore 3E and U-flute 3U options across HAL, HAS and HAX families.
These product families are primarily intended for aluminum cutting. Choose by slotting or profiling operation, cutter geometry and required tool dimensions.
2 vs 3 vs 4 Flute End Mills
Different flute counts offer different combinations of cutting edges and flute space. Compare chip evacuation, engagement and cutting conditions rather than selecting a cutter by flute count alone.
Fewer cutting edges generally leave more flute space, which can be useful when chip volume is high.
2刃エンドミルを見る →Three cutting edges combine a different edge-count and flute-space balance for slotting, side milling and profiling.
Current CategoryMore cutting edges may be useful for certain cutting conditions, provided chip clearance and machine rigidity are suitable.
4枚刃エンドミルを見る →3E vs 3U: Choose the Right 3-Flute Geometry
Compare the two available three-flute cutting geometries before selecting a model family and length variant.
3E — Square End Mill
A three-flute square-end profile for flat-bottom features, slots and profiles. Select the HAL, HAS or HAX family and cutter length to match the operation.
- Available families: HAL-3E, HAS-3E, HAX-3E
- Standard and selected extended-length variants
3U — U-Flute Square End Mill
U-flute geometry supports chip evacuation in aluminum cutting. Assess chip flow, engagement and the required cutting length when comparing HAL and HAS variants.
- Available families: HAL-3U, HAS-3U
- Standard, extended and extra-extended length variants

Slotting, Side Milling & Profiling with 3-Flute End Mills
Three-flute cutter selection depends on the type of cut, chip evacuation, cutter engagement and tool reach. Use the operation to narrow down the appropriate geometry.
Slots & Channels
For full-width slotting, consider chip removal and available cutting length. Compare 3E and 3U flute shapes rather than relying on flute count alone.
Flat-Bottom Pocket Milling
Square-end geometry can create flat pocket floors. Select a suitable cutting length and maintain chip clearance for the cavity geometry.
側面フライス加工およびプロファイリング
Check radial engagement, tool overhang and machine rigidity to balance cutting stability and the required wall finish.
For broader cutter selection by workpiece material, including ball nose and other end mill types, see アルミニウム用エンドミル.
3 Flute End Mill Dimensions & Length Options
Use the cutting and shank dimensions to specify a suitable tool. Match the family variant to the reach needed for your part.
The cutting length H is not automatically the maximum machining depth; actual usable reach depends on tool design and setup.
| Length Group | Model Suffix | Selection Consideration |
|---|---|---|
| スタンダード | 3E / 3U | Choose for the required dimensions and accessible features. |
| Extended | 3EL / 3UL | Check required reach, setup rigidity and cutting conditions. |
| Extra Extended | 3EX / 3UX | Review overhang and deflection risks in longer-reach applications. |
3-Flute End Mill Selection Checklist
Start with the machining operation and chip evacuation needs; then confirm the available three-flute geometry, family and cutter dimensions.
Define the Cutting Operation
Identify slotting, pocket milling or profiling, and note the cutter engagement and required finish.
Review Chip Evacuation
Consider chip concentration and flute space, then compare 3E square-end and 3U U-flute options.
Choose the Available Family
Review HAL economical, HAS high-performance and HAX high-precision series; 3U models are listed for HAL and HAS.
Confirm Size & Reach
Specify D, d, H and L, the selected family, and the required quantity for your quotation.
