سنفرة كربيد شكل شجري بنهاية نصف قطرية 1/4 × 5/8 بوصة

The radius end makes this burr glide smoothly into tight corners, and it cuts through hardened steel like butter without chattering. I’ve been using it for die grinding, and the 1/4” shank holds steady in my rotary tool. Exactly the tree shape I needed for detailed work.

Used it to hog out some aluminum this weekend and the 1/4" shank ran true with no wobble in my die grinder. The radius end left a smooth transition without needing to switch tools. This thing really saved me time.

The radius end on this tree burr really helps get into tight fillets without digging in like a straight one does. Cut through some mild steel smoothly and held its edge the whole session, so the 1/4" x 5/8" size feels just right for detail work.
