Kreg® 口袋孔鑽頭 XL

The etched markings on the collar are perfectly clear, so I can set my depth in seconds without squinting. Used it for a full weekend of cabinet frames and the hex shank never slipped once in my drill.

The hex shank fits my standard drill chuck without any adapter fuss, and the sight window makes depth setting embarrassingly easy even for a weekend warrior like me. Drilled maybe 40 holes through hardwood for a workbench and the stop collar never slipped once.

The etched markings on the collar are dead-on accurate, so I set the depth in seconds without even checking a ruler. The hex shank locks into my drill without any wobble, and the sight window made it easy to see exactly where I was cutting.
