Collection: Straight Flute End Mills

Straight Flute End Mills feature parallel cutting edges that minimize upward or downward cutting forces during machining. This helps reduce material lifting, tear-out, and delamination in softer or layered materials such as wood, plastics, laminates, and composites.

Best used for:

• Wood, plastics, laminates, and composite materials
• Thin workpieces where clean edge quality matters
• Operations where spiral-induced thrust could distort the part

Why choose it

• Reduces upward or downward thrust compared to helical flutes
• Helps prevent lifting, chipping, and edge tear-out
• Works well in abrasive or brittle materials where straight cutting forces are preferred
