Carbide Core Modular Extensions

Our universal carbide core modular extensions are ideal for standard inch end mill holders.

• Cylindrical inch shanks, providing adaptation for end mill holders, milling chucks and heat-shrink holders
• 3 sizes to accommodate modular head sizes from 3/4" to 1-1/2"
• Carbide core for enhanced vibration dampening capability, reduced deflection and improved rigidity
• Optional add-on extensions for additional 2" reach – screw on to base extensions (for 3/4" to 1-1/2" modular heads)
• Thru-coolant for delivery of air or coolant right at the cutting edge

Extensions feature a cylindrical shank, with no Weldon flats. Hold with high-performance milling chucks or heat/mechanical shrink holders, or mill Weldon flats and use a short-length solid end mill holder.
