🔧 Bosch 85152 Advanced Straight High Speed Construction Tool Review

With proper use, cleaning and resharpening these bits will last a long time. If used incorrectly, I can destroy any attachment in seconds without turning on the router.

I usually take breaks and let cool after each cut. But this one broke anyway. I'm not sure if the cool down period was too short or if it's just a little weak. So take your time if you need to use it frequently.

Recently used in a Dewalt DWP611PK to carve a custom Jolly Roger red oak for a brass insert. This was necessary to bring out small nooks and crannies (like his crooked teeth). The depth was 2.5mm and I cut through 10 square inches of solid material relatively quickly. I've had other milling heads that cracked in the heat and went fast, but this guy held up well to my abuse. After creating the outline I replaced it with a larger one to remove most of the wood for the inlay.
