    • A good buy at their current price point.
Size: 1/4" DIA - 7/8" CL - 1/4" SHK Number of Items: 5
When buying endmills I've been buying on a budget but have recently realized that it simply isn't always worth it because endmills that come out of the box dull will melt of burn material. Not only do these come sharp but retain that sharpness for quite a few jobs.

I used this spiral router bit to cut thru a thick aluminum manifold on my small block chevy motor. It cut flawlesssly and stayed sharp. I was pleasantly amazed at how well it worked and how durable it was.

Used it like I would on hardwood. Cut flawlessly on polycarbonate with a plunge router. 1/8" at a time, raising it to flush out the chips. Highly recommend.
