SC-3L Cylinder Shape Radius End PremiumTungsten Carbide Burr

Everything I hoped for

This works exactly as I hoped. I used this to port cylinder heads and it has good reach. Doesn’t jump on you but can really dig into some cast iron

Bought these to massage som oiling holes in an engine block. Worked flawlessly.

Good value

These work great. Good value for the money. I would recommend
