Seco 17004994 Square End Mill 0.5 in 4 Flute Cvd Diamond Carbide

Product Description

The SECO 17004994 is a single-end square end mill designed for precision milling of CFRP (carbon fiber reinforced polymer) and other composite materials. Built from micrograin solid carbide, it carries a CVD diamond coating that delivers the wear resistance needed to cut abrasive composite fibers without rapid edge degradation. The tool measures 0.5 inches in diameter with a 1-inch length of cut and a 3-inch overall length. Its 4-flute, 30-degree right-hand spiral geometry promotes chip evacuation while maintaining a smooth cutting action. CNC machinists and toolroom operators in aerospace, automotive composites, and advanced manufacturing install this tool in machining centers and CNC milling equipment.

The 17004994 belongs to SECO Series DIA430, a line engineered specifically for composite and CFRP machining. It is centercutting, allowing plunge entry, and features a straight 0.5-inch shank for standard collet or end mill holder compatibility. The right-hand cut and right-hand flute configuration suits conventional and climb milling in horizontal or vertical CNC machining centers. No extended reach or coolant-through capability is present, making it best suited for dry or mist-assisted cutting strategies typical in composite work.

Key Features

• CVD diamond coating optimized for abrasive CFRP and composite materials
• Micrograin solid carbide substrate for rigidity and edge integrity
• 4 spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design permits direct plunge entry
• Single-end configuration with straight shank for standard toolholding
• Tight mill diameter tolerance of -0.0010 / +0.0010 inches for dimensional accuracy

Compatibility

Designed as an OEM-style solid carbide end mill replacement for CNC machining centers and milling machines using standard 0.5-inch straight-shank toolholders or collets. Primary workpiece material rating is CFRP (material code C) per Series DIA430 specifications.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machining center spindle before changing tooling. Seat the straight shank fully into the collet or end mill holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout does not exceed the rated TIR maximum of 0.0005 inches before beginning a cut; excessive runout accelerates edge wear on diamond-coated tools.
