1-1/2" x 6" 扁鑽頭

Picked up this spade bit for a fencing job, and the 6-inch length was perfect for getting through those thick posts without swapping to an extension. The cut stayed clean all the way through, no grabbing or splintering on the exit side like my old bits did.

I was drilling through some thick oak beams for shelving, and the 1-1/2 inch diameter cut through cleanly without binding. The 6-inch shaft gave me enough reach to work in tight spots.

The longer 6-inch shaft gave me great reach for boring holes through thick framing lumber, which saved me from constantly swapping bits. It held its edge well through a full day of drilling.
