Seco 17003872 Compression Spiral Router Bit 0.25in Solid Carbide

Product Description

The SECO 17003872 is a compression-style spiral router bit designed for routing carbon fiber, composite, graphite, and green ceramic materials. Built from solid carbide with a diamond finish coating, this bit delivers clean cuts in demanding machined applications where surface delamination or fraying is a concern. It features a 30-degree helix angle and a chipbreaker router style, combining upcut and downcut geometry to shear material cleanly from both faces simultaneously. The 0.25-inch cutter diameter and 0.75-inch length of cut make it well suited for precision routing of thin-to-medium-thickness composite panels and sheets. Installation and use are intended for experienced machinists and CNC routing technicians.

This router bit is used in CNC routing operations involving advanced composite materials such as carbon fiber reinforced polymer panels, fiberglass composites, and graphite substrates. The compression flute geometry is particularly effective in production environments where top and bottom surface finish quality must both be maintained without secondary finishing. It is appropriate for use in vertical machining centers and dedicated CNC routing tables equipped with a 1/4-inch collet. The diamond coating extends service life when cutting abrasive materials that would rapidly wear standard carbide tooling.

Key Features

• Compression flute geometry shears material from both faces to reduce delamination in composite and carbon fiber workpieces
• Solid carbide construction provides rigidity and wear resistance in abrasive material applications
• Diamond coating extends tool life when routing highly abrasive substrates such as carbon fiber and graphite
• 30-degree helix angle with chipbreaker style promotes efficient chip evacuation and heat management
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Tight cutter diameter tolerance of -0.002 to +0.000 inches supports dimensional accuracy in close-tolerance routing

Compatibility

Designed for use in CNC routers and machining centers with a 1/4-inch collet; rated for carbon fiber, composite, graphite, and green ceramic material applications.

Installation Notes

This bit should be installed and operated by qualified CNC machinists or tooling technicians familiar with router bit handling and collet torque procedures. Always power down and lock out the spindle before changing tooling. Inspect the collet and collet nut for wear before seating the shank, and ensure full shank engagement per the machine manufacturer's minimum insertion depth guidelines. When routing carbon fiber or composite materials, use appropriate respiratory protection and dust collection, as fine particulate from these materials presents a health hazard.
