Case Study: Real Business, Real Results

Seattle, WA – Upgrading to a router that could handle abrasive circuit boards more efficiently.

"Switching to the 6PR extended length router cut our clean-up time by 30% thanks to its down cut action. The durability on glass-reinforced materials is impressive."

Jill Harper – Production Manager

Boosted routing efficiency and reduced equipment wear significantly.

Why the Diamond Cut Makes a Big Difference on Tough Materials

Diamond cuts are specially designed to withstand the wear and tear that abrasive materials can dish out—think of it like wearing out your favorite shoes on rocky terrain. The diamond-cut edges keep the router bit sharp longer because they’re essentially coated or made from materials tougher than traditional carbide. This means less downtime swapping out dull bits and more consistent, clean cuts. For working on things like glass-reinforced PCBs or epoxy composites—which can be rough on tools—it’s a smart choice that keeps your workflow smooth.

Installation and Maintenance Guide

Setting It Up

  • Ensure your router is unplugged before installation.
  • Clean the collet and bit shank to secure a solid fit.
  • Insert the router bit fully into the collet, leaving minimal shank visible.
  • Tighten the collet firmly but don’t overtighten to avoid damage.
  • Check that the cut direction matches your project needs (down cut for clean edges).

Keeping It Going

  • Clean the bit after use to remove debris and resin buildup.
  • Use a soft brush or mild solvent for thorough cleaning.
  • Inspect the bit regularly for dullness or chips.
  • Store in a protective case to prevent damage during downtime.
  • Replace the bit once you notice reduced cutting performance.

Buying Guide: Choosing the Right Extended Length Router

  • Need help Selecting? Consider the type of material you’ll cut most often—some bits are better for abrasive composites.
  • Not sure on the cut style? Down cut bits reduce breakout on delicate materials, while up cut provides faster chip removal.
  • Size matters—choose the correct head diameter and length to match your project depth and detail.
  • Look for durability when working with reinforced materials like phenolic-epoxy or glass-filled plastics.
  • Check router compatibility with the shank diameter and overall length of the bit.
  • Think longevity—investing in a diamond cut bit can save you money over time due to reduced wear.

Frequently Asked Questions
