Hello Chuck, This is Helical EDP# 59406 which is a 1/2″ diameter end mill with a 1-1/4″ length of cut. We ran this tool at 7,639 RPM, 344 IPM and 1,000 SFM with 1/2″ ADOC and 15% RDOC.

In this video we did not use it for demonstration but to prolong tool life, in a real-world situation, we would have used coolant. We recommend using coolant when available and when chip packing and heat are a possible issue.

Fully stocked and ready to ship today, Helical’s 5 Flute Variable Pitch Chipbreaker Rougher End Mills are offered in a variety of end profiles, neck designs, and sizes.

Dec 14, 2008 — Your best bed might be a carbide tipped drill bit. Go slow, use plenty of coolant/lube, and have a couple spare bits on hand just in case.

I’m having a hard time believing that’s a 1/2″ cutter also… that looks like a cat50 on a Haas and proportion wise….that looks like a 3/4″ tool

Great question! When running both conventional and climb milling the tool life would decrease but since you are able to machine faster, your end mill should perform the same. If you want to run both styles at the same time we suggest weighing out the benefits, do you need longer tool life or do you need to machine faster?

How does running the tool both directions (climb and conventional) affect the tool life? It certainly does make the operation faster.
