Replacement Carbide Inserts and Fasteners for 1" Insert Surfacing Bit (2 Pack, 10 Pack)

Keep your CNC surfacing bit performing like new with replacement carbide inserts and fasteners designed for the IDC Woodcraft 1" Insert Surfacing Bit (1/4" Shank).

This product is available in three replacement options:

• 2-Pack FK08 Carbide Inserts
• 10-Pack FK08 Carbide Inserts
• 2-Pack Replacement Fasteners (M4x6 T20 Button Head Screws)

Instead of replacing the entire cutter when it dulls, simply rotate or replace the insert and keep cutting.

Designed for CNC Surfacing Performance

These replacement inserts and fasteners are engineered specifically for CNC spoilboard resurfacing, slab flattening, epoxy cleanup, and surface preparation applications. Sharp inserts help maintain clean finishes while allowing efficient material removal.

Perfect for:

• CNC spoilboard resurfacing
• Slab flattening
• Epoxy surface cleanup
• Removing uneven or warped material
• Surface preparation before carving

FK08 Carbide Grade – Built for Clean, Consistent Cuts

The replacement inserts are manufactured using FK08 carbide, a wear-resistant grade engineered for smooth cutting performance and extended edge life.

FK08 carbide is ideal for CNC surfacing applications where finish quality and consistency matter most.

Why FK08 carbide performs well:

• Excellent wear resistance for longer cutting life
• Produces smooth, clean surface finishes
• Maintains a sharp edge over repeated use
• Consistent performance across spoilboard resurfacing jobs

Important Note:
FK08 carbide is optimized for smooth, controlled cutting—not heavy shock loads or aggressive abuse. For best results, use appropriate feeds, speeds, and stepovers during surfacing operations.

Carbide Insert Specifications

Why Keep Extra Inserts & Fasteners On Hand?

Spoilboard resurfacing is routine CNC maintenance. Keeping spare inserts and replacement hardware available means you can refresh your cutter instantly and continue working without interruption.

When the insert edge dulls, simply rotate or replace the insert and get back to cutting.

Backup fasteners also help:

• Reduce downtime
• Maintain proper insert retention
• Support safe cutter operation
• Keep CNC workflows moving efficiently
