AI Review Summary:

Across major retailers, buyers praise the HOLE DOZER’s durability and clean cutting in wood and light metals, noting quick plug removal via the open‑side slots. Many highlight the pre‑installed arbor and pilot bit as convenient and time‑saving. Common positives include long tooth life, smooth performance with cordless drills, and reliable sizing for recessed lights. Neutral/mixed feedback mentions slower progress in thick steel and the need to clear chips in deep cuts. A recurring complaint is occasional pilot‑bit wear or breakage under aggressive use and that cutting thick stainless or cement board is better suited to the carbide‑tooth version. Representative quotes: “Cuts wood with nails without missing a beat,” “Plug Jack slots make cleanout easy,” and “Works, but heavy-gauge steel pushes its limits—consider carbide for that.”
