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.
