Cat-4 1/4" Compression End Mill

1/4" Compression End Mill
Tungsten Carbide • Nano Blue Coated

Overview
Built for clean, chip-free edges on both the top and bottom of sheet goods. The compression geometry combines up-cut and down-cut flutes to pull fibers inward and reduce tear-out, making it ideal for plywood, laminates, and veneered materials on spindle-driven CNC machines.

Best For

• Plywood
• MDF
• Laminated sheet goods
• Veneered panels

Why Choose It

• Clean top and bottom edges in one pass
• Great for sheet goods and laminates
• Nano Blue coating reduces heat and friction
• Stable cutting at higher spindle RPMs

Starting Parameters
Conservative starting values for spindle-driven CNC machines.

• Spindle: 16,000–18,000 RPM
• Feed: 120–180 IPM
• Plunge: 40–60 IPM
• Cut Strategy: Run deep enough to fully engage the compression zone

Specifications

• Tool Type: Compression End Mill
• Flutes: 2
• Cutting Diameter: 1/4"
• Cutting Length: 1.5"
• Shank Diameter: 1/4"
• Overall Length: 2.75"

Notes

• Best performance comes at full or near-full material thickness
• Shallow passes will not produce clean edges on both faces
• Proper dust collection improves cut quality and tool life
